The formula for velocity is V=D/T, which stands for?

• Volume=displacement divided by time

• Velocity=displacement divided by time

• Velocity=distance x time

• None of the above

If a ball was dropped at 6feet and took 3 seconds to hit the ground what is the Velocity

• 2feet/second

• 9feet/second

• 3feet/second

• None of the above

What is friction?

• strength or energy as an attribute of physical action or movement

• the force that attracts a body toward the center of the earth, or toward any other physical body having mass

• is a force that resists the motion of one object against another.

• None of the above

Newton's 1st Law of Motion?

• says that acceleration (gaining speed) happens when a force acts on a mass (object)

• An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• states that for every action (force) in nature there is an equal and opposite reaction.

• None of the above

• None of the above
