Newtons laws and Forces

What is Newtons first law?

An object at rest will remain at rest and an object moving at constant velocity will remain moving at constant velocity unless a resultant force acts on it to change its state of motion. (Inertia)

What is Newtons second law?

The rate of change of momentum is directly proportional to the applied force and takes place in the direction of which the force acts. F= ma

What’s Newtons third law?

If object A exerts a force on object B, then object B will exert the same force on object A but in the opposite direction.

What is a force?

Force is the push or pull on an object

What is Weight?

The force an object experiences due to gravity

What is the SI unit for Weight?

Kgms^-2 / N

What is the Formula for Weight?

Weight = mass × acceleration due to gravity

What is Inertia?

The property of objects to resist changes in its state of motion
