Speed, Motion, & Energy Review

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

• 50 miles/hr

• 5 miles/hr
• 125 km/hr
• 50 km/hr

A man walks at 10 m/min for 5 min, what distance will he walk?

• 50 min

• 2 m

• .5 miles

• 50 m

A car accelerates as it rounds a corner, even if it is going at a constant speed. Why is that?

• Its direction changes

• It doesn't

• It slows down

• Its speeds up
