Back

speed and direction

Front

Which is an example of speed? A car driving 55 miles per hour south. A bicyclist traveling 10 meters per hour toward the next town. A roller coaster is traveling 10 meters per second. A rocket blasting off at 2,500 meters per second toward space.

Back

A roller coaster is traveling 10 meters per second.

Back

Speed

Front

A train is travelling North 220 km/hr. Is this speed or velocity? Options: Speed, Velocity, Neither, Both

Back

Velocity

Front

Is the following scenario an example of acceleration? A swimmer has 10 meters left in the race and he is neck-in-neck with his competitor. He has a surge of adrenaline and pulls ahead to win.

Back

Yes, this is acceleration since the swimmer starts to speed up to pull ahead.

Front

Is the dancer's action of doing 10 pirouettes in a row an example of acceleration?

Back

Yes, this is acceleration since the dancer is changing direction when she spins.

Front

True or False: You are standing at the bus stop and not moving at all. Since you are not moving, your acceleration would be 0 (zero).

Back

True since you are not speeding up, slowing down or changing directions.
