Question

17. Which of the following is an
example of non-uniform
acceleration?
*
(a)The motion of a bicycle going down
O the slope of a road when the rider is not
pedalling
O (b) The motion of a freely falling body.
O
(c) The movement of a car in a crowded
road.​

Answer 1

Answer:

(c) the movement of a car in a crowded road

Explanation:

the object travels unequal distance and speed in equal interval of time.so, car moved in a road with unequal distance and speed in equal interval of time.

Answer 2

The movement of a car in a crowded road (option c) is an example of non-uniform acceleration.

• Acceleration is described as a change in velocity with respect to time, according to the physics concept. However, an object's acceleration might vary based on the external force exerted to it.
• When velocity changes at equal periods of time, this is known as uniform acceleration.
• The motion of a freely falling body, for example, and the motion of a cycle travelling down a slope without a rider. Because the only force at work is gravity, which produces an object's uniform motion.
• When velocity changes unequally in an equal interval of time, this is known as non-uniform acceleration.
• Consider the movement of cars on a crowded road, where the vehicle's velocity varies at all times in the traffic conditions. The rate of acceleration is not constant.
• As a result, the correct response is for the car to move down the crowded road.
