Question

Identify the type of motion for each number

Answer 1

A :-) 1.) 3rd law of motion.

2.) 2nd law of motion ( law of inertia ).
- 2nd law states that if an object has more mass then it has more inertia ( mass = inertia ).
So , here the empty shopping cart is easier to push compared to loaded one.

3.) 1st law of motion.
- 1st law states that a object in rest will stay at rest , if a object is in motion it will stay at motion until a unbalanced force is applied on it.
So , here the baseball was in motion then , an unbalanced force ( bat ) was applied on it , so the was thrown up into the air.

4.) 3rd law of motion.
- 3rd law states that every action force has an equal and opposite reaction force.
So , here when your walking , your foot pushes the ground backwards ( action force ) , and the ground pushes your foot forward ( reaction force ).

5.) 1st law of motion.
