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

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
