Motion, Velocity, and Acceleration

When you know both the speed and direction of an object's motion, you know the

• average speed of the object
• acceleration of the object
• distance the object has traveled
• velocity of the object

If a bicyclist travels 30 km in 2 hours, her average speed is

• 30 km/h
• 60 km/h
• 15 km/h
• 2 km/h

It took 3.5 hours for a train to travel the distance between two cities at a velocity of 120 miles/hr.  How many miles lie between the two cities? 

• 34 miles 
• 420 miles
• 120 miles 
• 360 miles 

A car accelerates from a standstill to 70 m/s in 10 seconds.  What is the acceleration?

• 0.7m/s2
• 7m/s2
• 14m/s2
• none of the above

You ride your bike in a straight line at a constant speed of 10 km/h.

• Acceleration occurred because speed increased.
• Acceleration did not occur because neither speed nor direction changed.
• Acceleration occurred because you changed directions.
• Acceleration occurred because speed decreased.

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

• 80 m/s North
• 5 m/s
• 5 m/s North
• 24 m/s

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object
