Unit 5 Review: Motion PS

Scott drives a Jeep 12 km east, then 4 km north, then finally 3 km west. He traveled a total distance of:

• 5 km
• 10 km
• 13 km
• 19 km

A ping-pong ball rolls forward 6 meters, and bounces backward 3 meters. It traveled a total distance of:

• 9 meters
• 6 meters
• 3 meters
• 0 meters

Liza is swimming laps from one end of a 50 meter pool to the other. Going from one end to the other is considered one lap. If she swims four complete laps, which statement is TRUE?

• Her distance and displacement are both zero.
• Her distance is zero, but her displacement is 200 meters.
• Her distance is 200 meters, but her displacement is zero.
• Her distance and displacement are both 200 meters.

Ivan walks 10 meters west to the water fountain, then runs 2 meters east to his class to avoid a lockout. His displacement would be:

• 8 meters
• 8 meters, east
• 8 meters, west
• 12 meters

During a game of dodgeball, Marina runs 2.45 meters forward to grab a dodgeball, then runs 1.25 meters backward to avoid a opponent's dodgeball. Her displacement would be:

• 3.7 meters backwards
• 1.2 meters backwards
• 3.7 meters forwards
• 1.2 meters forwards

What two measurements are necessary for calculating speed?

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time

What is the speed of an object that travels 60 meters in 4 seconds?

• 240 m/s
• 15 m/s
• 0.067 m/s
• 15 mph

A measurement of how fast an object is moving

• Velocity
• Speed
• Vector
• Acceleration

Can be measured in seconds (s)

• Distance
• Time
• Speed
• Acceleration

What is the speed of an object that travels 20 meters in 4 seconds?

• 80 m/s
• 0.2 m/s
• 5 m/s
• 24 m/s
