On a distance vs. time graph, the steeper the slope _____

• the slower the speed
• the faster the speed
• less acceleration
• greater acceleration

Speed is different from velocity because

• Velocity has a direction
• Speed uses Distance /Time
• Velocity doesn't include time
• Velocity doesn't include distance

What is motion?

• the stopping of an object to a frame of reference

• a change in position relative to a frame of reference

• the middle ground between light and shadow, between science and superstition, and it lies between the pit of man's fears and the summit of his knowledge

• a change in the time in which it takes to get an office referral
