Ch. 2 Review: Motion and Forces (Energy)

Define distance

• total distance traveled and the direction you traveled
• total distance traveled
• how long you walk
• how fast you walk

What is displacement?

• total distance traveled and the direction you travel
• total distance traveled
• how long you walk
• how fast you walk

What is motion?

• change in speed
• change in time
• change in position
• change in velocity

Define speed.

• distance divided by time
• distance times time
• time divided by distance
• distance plus time

Define velocity.

• speed and time
• speed and position
• speed and direction
• speed and acceleration

Provide an example of velocity.

• 10 m/s
• 15 m/s
• 20 m/s
• 20 m/s East

Explain how you can travel at a constant speed, but have a changing velocity.

• speed up
• slow down
• change directions
• it is not possible

What is the formula for speed?

• s=d*t
• s=t*d
• s=d/t
• s=t/d

What are the units for speed?

• m
• m/s2
• s
• m/s

Define acceleration

• rate of change of velocity
• speed and direction
• total distance traveled divided by time
• how far you travel
