Question

Give two examples each of situations in which you push or pull to change the state of motion of objects.

Answer 1

Hint – In this question use the basic definition of push or pull. Push means to exert force away from the source of force, whereas pull means to exert the force towards the source of the force. Using these concepts to think of the examples keeping one thing in mind that we need to change the state of the motion of objects.

Complete step-by-step solution -
As we know the state or position of the motion of an object is changed when the position of the object is changed while moving w.r.t. to the previous position.
Example of pushing:
$\left( 1 \right)$ Pushing the trolley – when we push the trolley towards opposite to our side we have to apply the force called pushing force when this force is greater than the mass of the trolley than the trolley moved to opposite to our side.
$\left( 2 \right)$ Pushing the heavy rectangular box to change its original position – working of this is the same as above.
Examples of pulling:
$\left( 1 \right)$ Picking up a glass of water so that its initial position is changed – when we pick up a glass of water we have to do a work so that the glass of water changes its initial position, which is equal to the pulling force.
$\left( 2 \right)$ A magnet pulling metals towards itself – Just remember the case when we are kids any playing with some magnets when we placed the magnet in front of the metals it exerted a force called pulling force or attraction force so that metal and the magnet stick together this is called as pulling force.
So this is the required answer.

Note – There can be other examples of push or pull force that can change the state of motion of the ball, one can be that while playing football the player pushes the football to change its state of motion. Example of pull force includes when a rope is pulled from a well in order to draw water from it.
