An object moving at -5 m/s² is doing what?

• Speeding up

• Slowing down

• Moving at the same speed

• Stopped

The metric unit for velocity is ________.

• m
• m/s
• m/s²
• s

Velocity is different from speed because...

• Velocity is distance/time. Speed is displacement/time.

• Velocity is speed in a certain direction and can be positive or negative.

• Speed is velocity in a certain direction. Both can only be positive.

• Velocity is how much speed changes over time.

If you traveled from Point A to Point B to Point C, what would your DISPLACEMENT be?

• 3 miles

• 4 miles

• 5 miles

• 7 miles

What two measurements are necessary for calculating speed?

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