Which of the following is NOT an example of acceleration?

• Driving at a steady speed and turning left.

• Driving at a steady speed and then slowing down.

• A change in velocity from 40km/h to 65 km/h

• A car moving at a steady speed of 60 km/hr.

What is motion?

• the location of an object

• the change in position over time

• distance divided by time

• the velocity of an object

How do you calculate average acceleration of an object?

• Subtract the final velocity from the initial velocity and divide by time

• Subtract the initial velocity from the final velocity and divide by time

• Add the the two distances and divide by the total time

• Divide distance by time

In a race, Taylor ran the first 50 meters in 33 seconds and the second 50 meters in 32 seconds. What is his average speed during the race?  

Speed = distance / time 

• 1.54 m / sec

• 1.53 m /sec 

• 1.52 m / sec 

• 0.65 m / sec 

A measure of how far something moves in a given amount of time is called?

• distance

• acceleration

• speed

• motion

Speed in a specific direction is called

• velocity

• motion

• speed

• position

A correct measure of velocity would be

• 300 m/hr

• 7,800 m/sec

• 40 kn/hr north

A negative acceleration means that your object is _____. 

• not accelerating
• not moving
• speeding up 
• slowing down 

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

• 24 m/s²

• 18 m/s²

• 16 m/s²

• 16 m/s
