A train travels 142 miles in 2 hours.  What is its speed?

• 284 mph
• 1420 mph
• 71 mph
• 213 mph

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

What is the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d

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

A train covers a distance of 480 miles in 8 hours. If it is traveling at a constant speed, how fast is it going?

• 0.02 miles per hour

• 488 miles per hour

• 60 miles per hour

• 240 miles per hour

What is velocity?

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

When a car goes around a corner at 20 mph, why do we say it  accelerates?

• The car is accelerating because of the velocity is constant
• The car accelerates because it's going 20 mph
• Cars always accelerate when they are in motion
• The car is accelerating because it's changing direction

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• distance divided by the time interval 
• velocity divided by the time interval

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

A dog runs with an initial speed of 7.5 m/s on a waxed floor.  It slides to a stop in 15 seconds.  What is the acceleration?

• -7.5 m/s
• -7.5 m/s²
• -0.5 m/s²
• 7.5 mi//hr
