Force and Motion Test Review

How does friction affect speed?

• more friction decreases speed
• more friction increases speed
• less friction decreases speed
• less friction doesn't affect speed

Friction is a force that acts in an ___________ direction of movement.

• similar
• opposite
• parallel
• west

 What is the unit called that measures force?

• weight
• meter
• Newton
• kilogram

The friction that occurs when a liquid or a gas opposes the motion of an object describes

• fluid
• rolling
• sliding
• static

The friction that keeps non-moving objects in place describes

• fluid
• rolling
• sliding
• static

The type of friction that occurs when two solid surfaces slip past each other describes

• fluid
• rolling
• sliding
• static

The distance traveled by an object per unit time is called:

• Velocity
• Speed
• Momentum
• Acceleration

Motion is:

• An increase in the speed of an object
• A decrease in the speed of an object
• The stopping of an object relative to a frame of reference
• A change in position relative to a frame of reference

Find the speed of any object that covers 400 km in 5 hr.

• 40 km/hr
• 80 km/hr
• 2000 km/hr
• 800 km/hr

Velocity is:

• The same as speed
• The same as acceleration
• Speed in a specific direction
• The same as momentum
