03 Speed, Velocity, and Acceleration PRE-assessment

LT#1: What is the difference between velocity and the speed of an object?

• Velocity is the distance over time with NO direction; speed is the change in velocity over time.

• Velocity has direction; speed has NO specific direction associated with it

• Velocity has no direction; speed has a specific direction

• Velocity is speed over time; speed is distance over time

LT#1: Distance divided by time (ex: 60 miles/hr) is an example of...

• speed
