What is inertia?

• An object that is accelerating

• Gravitational force

• An objects tendency to stay at rest or in motion

• An unbalanced force

Newton's second law states.....

• If there is more mass then there is more acceleration

• An object at rest wants to be in motion

• Force = Mass x Acceleration

• The force exerted on an object is not related to mass or acceleration
