Velocity relies on what 2 things?

• acceleration

• speed

• distance

• direction

• time

Speed =

• distance / time
• time / distance
• distance * time

You walk 10 meters to math class in 20 seconds. Your average speed is

• 2 m/s

• 0.5 m/s

• 200 m/s

• 5 m/s

Acceleration is

• increasing speed

• decreasing speed

• changing direction

• the amount of inertia in an object

A car driving 100 miles per hour hits the brakes and slows to 50 miles per hour. This is an example of negative acceleration. True or False?

• True
• False

A student jogging at 2 m/s picks up the pace until she is jogging at 4 m/s. This is an example of positive acceleration. True or False?

• True

• False
