Multiple Choice

What is the definition of a characteristic of a moving object that is related to the mass and velocity of the object?

• Momentum

• Velocity

• Speed

• Force

Multiple Choice

How can you calculate momentum?

• Mass x Speed

• Mass x Velocity

• Weight x Speed

• Weight x Velocity

Multiple Choice

What is the unit for measuring momentum?

• kg x m/s

• f x m/s

Multiple Choice

When describing momentum you always use what two things?

• Speed & Direction

• Speed & Force

• Force & Direction

Multiple Choice

What does the law of conservation of momentum state?

• The total momentum of objects that interact does not change (not counting outside forces)

• The total momentum of objects that interact does change because you count outside forces

Multiple Choice

The state that exists when the only force acting on an object is gravity is called

• free fall

• inertia

• acceleration

• momentum

Multiple Choice

The acceleration due to gravity near the surface of Earth is equal to

• 9.8 m/s

• 9.8 kg x m/s

• 9.8 N

• 9.8 m/s²

Multiple Choice

Any object that travels around another object in space is a satellite.

• True

• False

Multiple Choice

Satellites in orbit around the Earth travel in almost circular path because Earth is

• centripetal

• free falling

• curved

• massive

Multiple Choice

An object traveling in a circle is accelerating because it is constantly changing

• speed

• velocity

• direction

• force

Multiple Choice

The force that causes an object to move in a circle is called centripetal force?

• True

• False

Multiple Choice

If you could turn off a centripetal force, ___________ would cause the object to fly off in a straight line.

• inertia

• momentum

• Earth

• force

Multiple Choice

______________ is the centripetal force that causes a satellite to move in a circle.

• String

• Space Shuttle

• Gravity

• Helicopter
