Forces Review

What is inertia?

• Inertia is the speed of an object in motion.
• Inertia is the energy stored in an object at rest.
• Inertia is the resistance of an object to changes in its motion.
• Inertia is the force that causes an object to move faster.

When a force is applied to an object, that object will ____________
