Final Answer:
1st Law: An object at rest stays at rest, and an object in motion stays in motion unless acted on by a force.
Examples: A book on a table doesn’t move until you push it. A rolling ball stops because friction (a force) slows it down.
2nd Law: Force equals mass times acceleration (F = ma).
Examples: Pushing a shopping cart lightly makes it move slowly; pushing hard makes it speed up. A heavy box needs more force to move than a light one.
3rd Law: For every action, there is an equal and opposite reaction.
Examples: When you jump, you push down on the ground, and the ground pushes you up. When you row a boat, the oar pushes water back, and the water pushes the boat forward.
