Physics Review #1

10 m/s is an example of

• velocity

• position

• acceleration

• speed

7 m/s north is an example of

• speed

• velocity

• position

• acceleration

What is the difference between the velocity and the speed of an object?

• Velocity is the change in distance over time, while speed is the change in velocity on time

• Velocity has a direction associated with it, while speed has no specific direction

• Velocity has no direction associated with it, while speed has a specific direction

• Velocity is the change in speed over time, while speed is the change in distance over time

Which of the following describes the velocity of an object?

• 45 m/s

• 35 m east

• 45 m/s east

• 35 km

Which of the following best describes the speed of an object?

• 30 m/s

• 30 m west

• 30 m/s east

• 30 m/s²

Which of these describes an object with the largest acceleration?

• an object with a small change in velocity over a small change in time

• an object with a small change in velocity over a large change in time

• an object with a large change in velocity over a small change in time

• an object with a large change in velocity over a large change in time

Which BEST describes the difference between speed and velocity?

• Velocity is instantaneous

• Speed is a vector quanity

• Speed includes rate of change and direction

• Velocity includes rate of change and direction

What is motion?

• Change in time

• Change in position

• change in velocity

• change in force

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down.

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
