Force- any push or pull on an object

Inertia- the tendency of an object to resist change to its state of motion

Greater mass=greater inertia

An object in motion will stay in motion unless another force is applied to it

Friction is a force that acts against moving objects

Force is measured in Newtons

Greater force=greater change in motion

Net force-the amount of force that is making the object change direction or motion

Force and motion

Speed=distance/time

Speed describes
