Motion#01-05 Speed and Acceleration

Find the speed of a person who covers 20 km in 5 hours. 

• 4 km/hr
• 100 km/hr
• 0.25 km/hr
• 5 km/hr

Suppose you take a trip that covers 180km in 3 hours. Your average speed is...

• 30km/hr
• 360km/hr
• 180 km/hr
• 60km/hr

meters per second (m/s) is a unit of:

• speed
• distance
• acceleration
• gravity

When you look at the speedometer in a moving car, you can see the car's 

• instantaneous speed
• average speed
• instantaneous acceleration
• average acceleration

Total distance divided by total time is

• average speed
• constant speed
• instantaneous speed
• acceleration

What is the speed of a cheetah that travels 112.0 m in 4.0 s?

• 0.0357 m/s

• 28.036 m/s

• 0.036 m/s

• 28.0 m/s

What does this graph represent?

• Constant speed
• Acceleration
• Not moving

If you double distance, what happens to the time traveled with the same speed?

• The duration of the trip is 4x longer. (time squared)

• The duration of the trip is 1/4 the time. (inverse of square)

• The duration of the trip is cut in half.

• The duration of the trip doubles.

At a constant speed what would happen to the distance if you doubled the time?

• The distance traveled is 4x longer. (time squared)

• The distance traveled is 1/4 the time. (inverse of square)

• The distance traveled is cut in half.

• The distance traveled doubles.
