Force changes motion
Newton's 3 laws can be used to describe the motion of objects
An object will remain at rest or in straight line motion unless acted on by a force
The change in movement of the object (acceleration) is proprtional to the amount of force applied (F= ma)
Every action has an equal and opposite reaction
Interestingly, because the force of gravity is proportional to the mass of an object and the acceleration of an
object is inversely proportional to the mass of the object(inertia), the net result is that everything falls at
the same rate under gravityNear the surface of the Earth, all objects fall at a rate of 9.80ms-2
