Kinematics Vector

On a graph showing distance versus time, a horizontal line represents an object that is

• moving at constant speed
• decreasing its speed
• increasing its speed
• not moving

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

A change in velocity over time is known as:

• acceleration
• constant speed
• average speed
• displacement

Velocity is both ____ and _____. 

• speed , direction 
• direction, mass
• volume, density 
• direction, magnitude 

What is this graph representing?

• Constant Speed
• Acceleration (speeding up)
• Deceleration (slowing down)
• No motion

At 60 seconds, how far had this object traveled? 

• 0 m
• 10 m
• 20 m
• 40 m

What is happening at D?

• Stationary
• Accelerating
• Fast steady speed; moving away from the starting position
• Slower steady speed; moving away from the starting position

An object can be moving for 10 seconds and still have zero displacement.

• True
• False

A quantity that is has magnitude and  direction is referred to as a

• vector quantity
• scalar quantity

A car slows down from +32 m/s to +8 m/s in 4 s. The acceleration is 

• 6 m/s/s opposite the motion
• 2m/s/s in the direction of motion
• 8 m/s/s opposite the motion
