Give exa

Answer 1

In physics, motion is a change in position of an object over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, time, and speed. 

Examples (i) Motion of a vehicle on a straight line.

(ii) Motion of a train on a straight railway track.

(iii) Motion of an object dropped from a certain height from the ground.

(iv) A man working on a straight path etc.

Answer 2

Here motion means when force applied to a body then it start to move according to newton's law every body having some motion whether it rotational, straight, rectilinear motions. it depends upon apply the force on a body.Example:

If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one. This means that more force is required to push the full shopping cart.
