First Law (Law of Inertia)
An object that is not moving will stay still.
An object that is moving will keep moving at the same speed and in the same direction.
This will happen unless something else, like a push or pull, makes it change.
For example, if a car is going 60 miles per hour, it will keep going at that speed until the brakes are applied. Brakes are a force that stops the car.
Second Law (Law of Acceleration)
How fast something speeds up (acceleration) depends on two things:
You can remember this with the simple formula:
Force (F) = mass (m) × acceleration (a).
For example, if you push a 2 kg object with a force of 10 Newtons, it will speed up at 5 meters per second squared.
Third Law (Action and Reaction)
For every action, there is an equal and opposite reaction.
This means whenever you do something, like pushing or jumping, there is always a reaction against it.
For instance, when someone jumps, they push down on the ground. At the same time, the ground pushes back with the same strength, helping them go up.
Importance
Newton's laws are very important in science.
They help us understand how things move and work.
These laws have been used for over 300 years and are essential in engineering, space travel, and many other fields of science.
They provide the basic understanding needed to develop new technologies and explore our world.
