Question

Give 2 examples each of uniform and non-uniform acceleration.

Answer 1

Uniform motion:

When a car is moving at a constant velocity of 50Km/hr in a straight line, the car is covering equal distances in equal intervals of time irrespective of the length of time. Then we can say that the car is in uniform motion.

For example:

1. Uniform circular motion:

1. When a table fan rotates at a constant speed then it can be described as a uniform circular motion.
2. As it is rotating in a circle in which at all instances change of direction is taking place and movement is uniform.

2. Uniformly accelerated Motion:

1. When a body falls freely, then it accelerates uniformly with a magnitude of acceleration due to gravity. Thus the velocity of the body increases by equal amounts in equal intervals of time.
2. Hence it can be referred to as an example of uniformly accelerated motion. also circular.

Non-Uniform motion:

When a race car constantly accelerates to win the race, then the car travels unequal distances in equal intervals of time. Hence such an instance can be referred to as an example of non-uniform motion.

For example:

1. Non-uniform circular motion:

1. The motion of a table fan when it is switched off till its stops, can be referred to as an example of non-uniform circular motion.
2. As the rotation of the fan is not constant and it is changing with time.

2. Non-uniformly accelerated motion:

1. When a feather falls in a heavy storm, then the velocity of the feather decreases sometimes and sometimes it increases in unequal amounts in equal intervals of time.
2. Thus it can be referred to as an example of non-uniformly accelerated motion.
