Force and Motion

What is friction?

• Friction is the force that opposes motion.

• Friction is the force that causes motion.

• Friction is the force that accelerates motion.

• Friction is the force that supports motion.

What is the force that pulls objects towards the center of the Earth?

• magnetism

• friction

• electricity

• gravity

Which of the following is an example of a non-contact force?

• Friction

• Magnetism

• Tension

• Gravity

What is inertia?

• Ability to change motion easily

• Tendency to remain in motion

• Speed at which an object moves

• Resistance to changes in motion or rest

What is the SI unit of force?

• Newton (N)

• Kilogram (kg)

• Meter (m)

• Second (s)

Which of the following is an example of a force?

• A push or pull

• Color

• Temperature

• Gravity

A force that acts on an object to slow or stop its motion

• speed
• friction
• gravity
• unbalanced forces

the amount of matter an object has is its

• velocity
• mass
• inertia
• momentum

An increase in speed or a change in velocity is

• force
• momentum
• acceleration
• balanced forces

The change in the position of an object is

• direction
• momentum
• friction
• motion
