1661 - What are Newton's three laws of motion
Newton's three laws of motion are simple rules that help us understand how things move. Here's a brief explanation:
First Law (Law of Inertia): An object at rest stays at rest, and an object in motion stays in motion, unless it's pushed or pulled by a force.
Example: Imagine you're sitting in a car. If the car is moving, you'll keep moving too, unless the brakes are pressed (a force that stops the car) or you push the door open to get out (another force).
Second Law (Force and Acceleration): The more force you apply to an object, the faster it will move. But, if the object is really heavy, it's harder to make it move.
Example: Think of pushing a toy car and a real car. If you push a toy car gently, it'll move pretty fast. But, if you try to push a real car gently, it won't move much at all because it's really heavy.
Third Law (Action and Reaction): When you push or pull something, it always pushes or pulls back on you with the same amount of force.
Example: If you throw a ball, the ball not only moves away from you, but it also pushes back on your hand with the same amount of force that you used to throw it.
