Inertia is an objects ability to resist a change in motion... Which of the following best represents Inertia?

• When paddling a canoe, you push the oar backward and the canoe moves forward.

• A balloon playing around the room when the air is let out of it.

• A motorcycle requires less force to accelerate than a truck.

• Moving forward when your bicycle suddenly stops moving due to hitting a curb.

An objects acceleration depends on the objects mass and the amount of force applied.
