Explanation:
The objects can be different, or their surroundings.
For example, if you push a ball down a hill, and a box down a hill, with the same force, they will obviously have different outcomes.
Plus, if you throw a ball through a window, and then throw another one straight through the hole (with equal force!), they won't go the same.
I hope this helps :) if so, brainliest would help me out a lot <3
