Motion

What does the term displacement mean?

• The direction of motion

• The distance traveled divided by time

• The change of position of an object

Which of the following is the closest match to the definition of motion?

• An objects change in position relative to a reference point
• The change in position of an object
• Constant speed

What is the definition of velocity?

• A force that opposes motion
• Uniform circular motion
• The speed of an object in a particular direction

What is the definition of speed?

• Distance/Time
• Change in velocity/Time
• A change in momentum

How is velocity different than speed?

• Speed opposes velocity
• Velocity is speed with a direction
• None of the answers are correct

Which of the following represents the equation for acceleration?

• a = ƒt/v
• a = Δt/f
• A = Λd/t
• a = Δv/t

The graph shows

• positive velocity that's getting faster

• negative velocity that's getting faster

• negative velocity that's getting slower

• positive velocity that's getting slower

The graph shows

• positive velocity that's getting faster

What is a system of objects that are NOT moving with respect to one another?

• displacement

• a van traveling in the lane next to your car

• frame of reference

• relative motion

Movement in relation to a frame of reference is called

• distance

• relative motion

• motion

• displacement
