Questions for Discussion: Virtual Car: Velocity and Acceleration
What is the difference between speed and velocity?
Define acceleration. What does it mean besides an increase in speed?
What if the graph showed acceleration rather than speed? Where would the line be when the car was continuing at a constant speed of 40 mph in the same direction? Where would the line be if the speed were continually increasing? Decreasing?
An object, such as a planet, circling another object, such as the Sun, at a constant speed is said to be accelerating. Explain why this motion is an example of acceleration.
