Speed, Velocity, Acceleration Review

What is the equation to calculate time?

• time = speed/distance
• time = distance/speed 
• time = speed x distance 
• time = distance x speed

What is the equation to calculate distance?

• distance = speed/time
• distance = time/speed
• distance = speed/distance
• distance = speed x time 

Dave runs a 400 m race with a speed of 4 m/s. What time will it take him to finish the race?

• 400 minutes

• 100 minutes

• 100 seconds

• .25 seconds

A runner races in the 100 meter dash.  It takes her 10 seconds to finish.  What is her average speed?

• 10 m/s
• 1000 m/s
• 100 seconds
• 10 seconds

What is velocity?

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

A roller coasters accelerates from an initial velocity of of 6.0 m/s to a final velocity of 70 m/s over 4 seconds.  What's the acceleration?

• 24 m/s²
• 18 m/s²
• 16 m/s²
• 16 m/s

A car starts from rest at a stop light and reaches 20 m/s in 3.5 s. Determine the acceleration of the car.

• 2.2m/s²
• 7.0m/s²
• 5.7m/s²
• 70m/s²

Speed=

• T/D
• D/T
• S x T
• D x T

Which is an example of VELOCITY?

• A dog running at 3 m/s
• A deer sprinting at 4 m/s
• A migrating bird headed south for the winter at 3 m/s
• A person not moving at all

• Object not moving
• Object accelerating
• Object slowing down
• Object staying at a constant speed
