Unit 1 Motion Review

What equation do I use to calculate distance?

• S = D/T
• T = D/S
• D=TS

What does this graph represent?

• distance vs time (an object moving)

• Acceleration vs time (an object speeding up or slowing down)

• Not moving

What is the equation to calculate speed?

• speed = distance/time
• speed = time/distance
• speed = time x distance 
• speed = speed/time 

What is speed?

• How far you go

• How fast you accelerate

• How much distance is covered over a period of time

• The change in location of an object.

What two measurements are needed to calculate speed?

• mass and time

• temperature and mass

• time and distance

• distance and energy

Distance and direction of an object's change in position from a starting point

• displacement
• distance
• motion
• reference point

A ping-pong ball rolls forward 6 meters, and bounces backward 3 meters. It traveled a total distance of:

• 9 meters
• 6 meters
• 3 meters
• 0 meters

formula used to find displacenemt when an object travels at a right angle.

• subtract

• a2 + b2 = c2

• Add

• Multiply

How to find the total distance an object traveled?

• Add

• Subtract

• Multiply

• a2+b2=c2

How to find the displacement of an object that traveled in a straight line (ex: North to South)

• add

• subtract

• multiply

• a2+b2=c2
