Linear Motion Vocab

If you know how far an object travels in a certain amout of time you can calculate

• displacement
• speed
• acceleration
• momentum

Because velocity has both a magnitude and a direction it is a 

• distance
• speed
• scalar
• vector

Velocity is:

• speed and a specific direction
• the same as speed
• just a direction
• acceleration and a specific direction

Speed is:

• a measure of how fast something is moving
• the distance covered per unit time
• measured with a unit of distance divided by a unit of time
• all of above

Total distance over total time

• average speed
• constant speed
• acceleration
• gravity

Speed that doesn't change 

• constant speed
• average speed
• acceleration
• density

When you look at the speedometer in a moving car, you can see the car's

• average distance traveled. 
• average speed.
• instantaneous speed.

What is speed?

• speed=distance/time
• speed=distance*time
• speed=distance-time
• speed=distance+time

What is the average speed of a runner that goes 48 m in a total time of 6 seconds? 

• 6 m/s
• 7 m/s
• 8 m/s
• 9 m/s

meters per second (m/s) is a unit of:

• speed
• distance
• acceleration
• gravity
