Inertia affects all objects.
When the flicked coin struck the stack of coins, inertia caused the new coin to move.
Inertia causes an object that is stopped to stay stopped.
Inertia causes an object that is moving to stay moving.
Forces can cause an object to move.
Friction causes something to stop moving even if it doesn’t hit something.
For every action there is a reaction.
The stack of pennies remained motionless at the beginning of our activity because of friction, gravity, and inertia.
Forces can be transferred between objects.
Wearing a seat belt uses inertia because when the car stops, you stop.
