Speed and Velocity and Motion

Intro to 1-Dimensional Motion: Vectors

Velocity and Displacement

Multiple Choice

What is a difference between distance and displacement

• Distance is measured in seconds and displacement is measured in meters

• Distance is always shorter than displacement

• Displacement can be equal to zero if the object ends in the place it began in

• Distance can be equal to infinite when only a small distance has been travelled

Multiple Choice

30 m/s

• speed

• velocity

• -1.2 m/s

• -0.2 m/s

• 0.2 m/s

• 1.2 m/s

Multiple Choice

What is this graph representing?

• Acceleration (speeding up)
• Deceleration (slowing down)
• No motion
