The property of a moving object to continue moving is what Galileo called:

• Velocity

• Speed

• Acceleration

• Inertia

According to Newton’s First Law of Motion,

• An object at rest eventually begins to move

• An object in motion moves in a parabolic trajectory unless acted upon by a net force.

• An object at rest always remain at rest.

• An object at rest remains at rest unless acted upon by a net force.

If an object is moving, then the magnitude of its ____ cannot be zero.

• Velocity

• Speed

• Acceleration

• A and B

A body drop in free fall a vacuum,

• Will drop the same distance during each second of its fall.

• Will have the same average speed during each second of its fall.

• Will not be accelerated during its fall.

• Will have the same acceleration during second of it fall.

• It will hit the ground in less than three seconds at a speed greater than 12 m/s.

• It will hit the ground in more than three seconds at a speed less than 12 m/s.

• It will hit the ground in less than three seconds at a speed less than 12 m/s.
