What is inertia?

• The force exerted by gravity on an object.

• The tendency of an object to resist a change in motion unless an outside force acts on it.

• The constant velocity of a falling object when air resistance equals gravity.

• The motion of a body when only the force of gravity is acting on it.

What does weight measure?

• The path of a projectile.

• The velocity of a falling object.

• The gradulated force exerted on an object.

• The mass of an object.

What is free fall?

• The motion of a body when only the force of gravity is acting on it.

• The tendency of an object to resist a change in motion.

• The product of mass and velocity.

• The curved path of a projectile.

What is terminal velocity?

• The tendency of an object to resist motion.

• The force exerted by gravity on an object.

• The constant velocity of a falling object when air resistance equals gravity.

• The velocity of an object when it is launched.

What is projectile motion?

• The tendency of an object to resist a change in motion.

• The curved path that an object follows when a thrown launched or otherwise projected near the surfaces of earth.

• The constant velocity of a falling object.
