Motion class 9

This is a velocity-time graph.  What is the object doing in segment C?

• Positive acceleration
• Negative acceleration
• Constant Velocity
• Not moving

What is the rate of change in velocity known as?

Speed =

• distance / time
• time / distance
• distance * time

The area under a velocity-time graph represents the...

• ...acceleration.

• ...distance travelled.

• ...displacement.

• ...average speed.

Acceleration is

• increasing speed
• decreasing speed
• changing direction
• all of the above

An object is _____ if its position changes relative to another object.

• in motion
• at reset
• a frame of refence
• magical

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

You walk 10 meters to math class in 20 seconds. Your average speed is

• 2 m/s
• 0.5 m/s
• 200 m/s
• 5 m/s

You walk 10 meters to math class in 20 seconds. Your average speed is
