CH3 S2 Newton's laws of motion
Newton's first law
It states that an object moves at a constant velocity unless an unbalanced force acts on it. And if an object is in rest the velocity is 0 until an unbalanced force acts on it.
Example:
When a car stops and your body still keeps moving to the front.
This law can also be known as law of inertia.
Newton's second law
F = ma
Mass and acceleration
The acceleration of an object depends on its mass and the force acting on it. All force, mass, and acceleration are related
The law describes how the mass of an object, the force acting on it, and acceleration are all related.
Example: When you throw a ball it has more acceleration when it leaves your hand than when it is falling to the ground.
Newton's third law
When an object exerts a force on other object and vise versa with the same strength, they cancel eachother.
For every action there is an equal and opposite reaction
Example: if you push a wall, the wall is not going to move it returns the force. Another example is when you are in a pool and push the wall with your legs you obtain acceleration
Inertia and mass
Mass is the amount of matter of an object.
Inertia happens when an object is moving and it stops. because the nature of the object is to keep moving.
Example: there are two boxes and one has more mass than the other, the one with less mass will be easier to move.
