I would like to share learning-related tips and tricks for lifelong learners
Physics is a subject based on different formulas. It mainly contains the concepts of speed, velocity, acceleration, and distance. Everything you see in your surroundings works as per the formulas of Physics. Speed, velocity, and acceleration are the three basic concepts in Physics and every object works on these three concepts. They are the basic physics formulas which you should know for mastering the subject. Let us discuss in detail the relation between Speed, velocity, and acceleration.
Speed
Meaning
You may think that Speed and velocity are similar terms, but they are not actually. Speed is the measurement of how a thing moves. You can divide the speed into fast and slow. It has a numerical value.
Formula of speed
We have been learning the average speed formula since the school days.
It is Speed= Distance/ Time.
Average Speed
The average speed of the thing is the distance that the object travels divided by the time taken to travel that distance. It is defined by magnitude. Further, the average speed is the change of distance with time.
Ways to calculate the average speed
Constant speed is an important concept in this formula. If an object moves at a constant speed, the formula for speed will be as under:
Speed= total distance/elapsed time
Mostly, the object travels at different speeds at a particular distance. For example, the speed of the car does not remain the same throughout the journey. It changes on the trip. There are some reasons why the speed of the car changes in the trip such as red light, speed breakers, and other obstructions on the road. These hurdles slow down the car’s speed. Then the formula of the average speed of the car will be as under:
Average speed= total distance/ elapsed time
Average speed is measured in units of distance such as miles per hour, meters per second or feet per second.
Examples of average speed
A freight train travels a distance of 160 miles in 4 hours. Calculate the average speed of this train.
Average speed= Total distance/ elapsed time
160/4 hours = 40 miles per hour
A boy drove 50 miles trip to his aunt’s house in 2 hours. His return trip took 3 hours. Calculate the average speed of this trip.
Average speed = Total distance/elapsed time, Rate=distance/time
Rate(mph) | Time (hr) | Distance(miles) | |
To | 50/1=50 | 1 | 50 |
Return | 50/2=25 | 2 | 50 |
Average speed= 50(1) + 25(2)/ 1+2 = 50+50/3
100/3= 30.34 mph
Velocity
The next important concept is velocity. It is the rate at which the thing or object changes its position. It can be defined both in numerical value and direction.
The average velocity formula is the distance covered divided by speed + direction of travel.
Let us have a look at the problems of velocity.
A person walked 6 km in just 2 hours and 3 km in just 1 hour in the same direction. Calculate the man’s average velocity for the journey.
Average velocity= distance/time= 6 km+ 3 km/2 hours + 1 hour= 9km/3 hours = 3km/h
A man begins to walk from a point on a circular field of radius 1.5 km and after 2 hours you are at the same point. Calculate the average velocity for this journey.
Average speed= distance/time= circumference/time= 2*1.5*3.14/2 hours= Pi km/h= 3.14 km/h.
If you walk in a circular area and come back to the same point where you began walking, the displacement will be zero. Then the average velocity will also be zero.
A car goes to the east direction for 120 meters in 6 seconds and then turns towards the west direction for 60 meters in 2 seconds. Calculate the average velocity.
Distance= 120 meters + 60 meters= 180 meters
Displacement= 120 meters – 60 meters= 60 meters, to east
Elapsed time= 6 seconds + 2 seconds= 8 seconds
Average velocity= Displacement/ time elapsed= 60 meters/ 8 seconds= 7.5 meters/second.
Acceleration
The third important concept in Physics is Acceleration. Acceleration is the measurement of the change in velocity of a particular object at a certain time. The time is normally 1 second. Further, the velocity of the object may increase or decrease at a certain time.
Acceleration Formula
It is measured in meters/second squared.
When an object changes velocity by time, it is known as constant acceleration. When an object changes the velocity by decreasing, it is known as Negative acceleration.
There are 2 equations for acceleration. The first formula includes force, mass, and acceleration which is as under:
F=ma
The second formula is as under:
Acceleration= change in velocity/ change in time
Examples
Calculate the acceleration of the object moving with uniform velocity.
When there is uniform velocity, the initial and final velocities are equal to V. The formula is as under:
Average acceleration= change in velocity/ change in time.
So, the acceleration of the object traveling at a constant velocity is zero.
The speed of the car decreases from 75 km/h to rest in 30 seconds. Calculate the acceleration of the car in m/s2.
The initial velocity of the car is 75km/h and the final velocity is 0.
Average acceleration= 0-75 km/h/ 30 seconds=
We should now convert 75 km/h into m/s as under:
75 * 1000m/ 3600 s= 20.83 m/s
Average acceleration= -20.83m/s / 30 seconds= -0.69 m/s2
A car has a constant velocity of 60 km/h accelerates for 36 seconds at 1.5 m/ s2. Calculate the velocity of the car at the end of 36 seconds of acceleration.
Solution: The initial velocity of the car is 60 km/h.
Average acceleration= 1.5 m/s2= V- 60 km/h/ 36 seconds
The equation is as under:
V – 60km/h= 1.5m/s2 * 36 seconds= 54 m/s
We have to now convert 54 m/s into km/h
54 m/s= 54 m *(1km/1000m) / (1s * 1h/3600s)
= 54 * 3600 / 1000 km/h= 194.4 km/h
V = 194.4 km/h + 60 km/h= 254.4 km/h.
Interesting facts you may not know about speed, velocity, and acceleration.
The first scientist to measure the speed was Galileo.
Gravity is related to acceleration. The object falling towards the earth has increasing acceleration and low speed. It is because of earth’s gravity.
The speed of the light is fastest in the universe.
Newton stated that the Kinetic energy of a traveling object is linear and the square of the velocity. The velocity of the thing is changed by the mass of the thing.

Write a compelling and catchy introduction. Mention an interesting fact related to your topic into the intro.
How to write the middle part of the essay?
The primary focus is on the 1st body, this paragraph need not be as catchy as the previous stages. So, here you can mention some weak points in order to elaborate on the essay further.
The first paragraph - Write the strongest points or essential facts in the first paragraph
The second paragraph - Tries to elaborate of an essay further and adds more intriguing points.
The third paragraph - Cite some exciting examples with catchy tone related to the topic in the third paragraph
Who do not understand how to conclude an essay without sounding abrupt. Even though the conclusion is supposed to be short and sweet, it is an underrated part of an essay, and most of the students seem to be ignorant of how they should end an essay.
You need to persuade the reader with your arguments and ideas put forward by you in the essay and make your readers care about your ideas.
The majority of the students fail to understand is the fact that a proper link between the introduction and the conclusion of an essay can prove to be extremely fruitful.
If you have stated an idea in the intro, you can add a line or two elaborating that point in the conclusion. Expand the theme that you introduced in the intro without making it seem like you are merely repeating a certain fact to fill up pages.

Research work helps in knowing how to prepare for an exam or assignment. It will further help you to learn concepts on your own and develop self-learning skills. You can answer even the most difficult question out of your syllabus. This will further increase the self-confidence in the exams and assignments.
Exercise is as important as a healthy diet. Exercise improves blood circulation and focus. Kids love to play and to add up little fun workouts. Stretching would help them relax their muscles and concentrate better. There have been studies concluding that stretching helps in blood circulation and therefore helps in focusing. Few exercised would help in unclogging the mind and stay fresh.
The fresh air would be good for their brain circulation. This improves brain functioning. Specific exercises can also help build concentration. You can do them with the child to set an example. Yoga is also one of the ways the kids can stretch themselves. The exercises in yoga can also help in concentration building.
Breaks are as important as sitting down and focussing. We usually make the mistake of allotting the time for each activity by the kids. For instance, the time of playing football would be fixed from 5 pm to 6 pm and after that homework and studies. We do not allot time for breaks between studies. Parents need to understand the fact that kids need planned breaks between the studies.
For instance, if your kids have finished homework of the day, then it would be better to give him stretching or water break in between for 10 to 15 minutes. This would refresh his mind and help him concentrate better. Further, sitting for a long time is as injurious to health. It has the same effect as smoking. Sitting for long periods slows down metabolism. This causes weight gain. The slow metabolism also slows down the thinking power. This usually results in lethargy. You would definitely not want your kid to gain weight and become a house of different diseases related to weight.
