The equation for speed is:

• distance x time
• distance/velocity
• time/distance
• distance/time

The formula for calculating acceleration is ____________________

• time / final velocity - initial velocity
• initial velocity - final velocity / time
• final velocity - initial velocity / time
• time / initial velocity - final velocity

A ball thrown at 30m/s N is an example of

• speed
• velocity
• acceleration
• all of the abaove

Slowing down to keep from running a red light at an intersection is best defined as an example of

• speed
• velocity
• acceleration
• none of the above

Motion is

• an increase in an object's speed
• a decrease in an object's speed
• a change in position relative to a reference point
• the stopping of an object relative to a reference point
