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.

Best ways to learn Physics easily

10 steps to effective listening

Here are the ten steps that can help you to have effective listening:

1.) Face the speaker and always maintain eye contact.

2.) Pay attention, but be relaxed.

3.) Have an open mind and listen to them without judging them.

4.) Carefully listen to the words and try to understand what the speaker is saying.

5.) Never interrupt the speaker, nor impose your thinking on them.

6.) When the speaker takes a pause only then ask a question.

7.) Never ask things unnecessarily, only ask to have a better understanding.

8.) Try to feel what the speaker is feeling and communicating.

9.) Try to give simple and regular feedback to the speaker.

10.) Focus on non-verbal cues like facial expressions and gestures.

How many types of listening skills

Basically, there are two types of listening skills:

Discriminative listening

This type of listening is developed in the initial stages. This is the most basic kind of listening and does not require any effort as such in understanding the meaning of words or the phrases but just different sounds are produced.

For example, in early childhood, a distinction can be made between different sounds that get improved as the child grows up. As we move from childhood towards adulthood this distinction increases with the capacity to distinguish between different sounds.

Comprehensive Listening

Comprehensive listening is a broad term and it basically includes understanding the messages being communicated to the other person. It is also fundamental to all listening sub-categories.

For a person to develop comprehensive listening the listener first has to have an appropriate vocabulary and other language skills. This kind of listening gets more complex as the same message given to two people might result in understanding it with different meanings.

Comprehensive listening is also complimented by sub-messages through non-verbal communication like the tone of the voice, body language, and gestures. This kind of non-verbal signals can help immensely in communication and comprehension but might also confuse and might lead to misunderstanding.
