Question

mention the type of motion in each of the following
1) A ball moving vertically upward

2) A child moving down a slide

3) Movement of player in football ground

4) motion of wheel

Answer 1

Answer:

motion of a wheel

Explanation:

Answer 2

The type of motion in the following cases:

1. A ball moving vertically upwards : This is an example of accelerated linear motion in which the ball travels along a straight line and gravity acts in a direction opposite to that of displacement.

2. A child moving down a slide: A slide can be considered as an inclined plane. The child follows accelerated linear motion. Here a component of the the weight vector moves the child along a straight line on the inclined plane.

3. Movement of player in football ground:

A footballer follows accelerated non linear motion while playing in a football ground because he moves haphazardly and his velocity vector changes very often.

4. Motion of wheel:

Motion of a wheel can be described as rolling motion. Rolling motion is a combination of rotational motion and translational motion of the wheel
