Speed velocity distance and displacement practice test
What is the difference between distance and displacement?
Distance vs. Displacement • You drive the path, and your odometer goes up by 8 miles (your distance). • Your displacement is the shorter directed distance from start to stop (green arrow). • What if you drove in a circle?
What is the difference between velocity and average speed?
• Speed (v) – how fast you go • Velocity (v) – how fast and which way; the rate at which position changes • Average speed ( v) – distance/time • Acceleration (a) – how fast you speed up, slow down, or change direction; the rate at which velocity changes Speed vs. Velocity
What is the symbol for velocity on the speedometer?
• The symbol for velocity is type written in bold: v or hand written with an arrow: v Speed vs. Velocity • During your 8 mi. trip, which took 15 min., your speedometer displays your instantaneous speed, which varies throughout the trip.
What is the distance an object moves in?

Average speed = distance / elapsed time Is the average speed of the red car 40.0 mi/h, more than 40.0 mi/h, or less than 40.0 mi/h? Could average speed ever be negative? 18 Average Velocity • Say takes time ∆t for an object to undergo a displacement • The average velocity is rate at which the displacement occurs • SI Unit: m/s
