Motion Quiz Review

What is the SI unit for distance?

• second

• meter / second

• gram

• meter

Which of the following BEST describes the difference between "distance" and "displacement"?

• Distance measurements can't be negative, while displacement measurements can be negative

• Distance measures the change of position of an object in motion, while displacement measures the direction in which an object traveled.

• Distance is a measure of the total length of the motion, while displacement is the difference in position between starting and ending positions including direction.

• Distance measurements are recorded in meters, while displacement measurements are recorded in feet.

__________ is defined as the distance an object travels per unit of time.

• Speed

• Displacement

• Acceleration

• Motion

What is the symbol for the SI unit for speed?

• s

• m/s

• m

Speed can be calculated using which of the following equations?

• $s=d\times t$

• $s=d\div t$

• $s=t\div d$

• $s=d\pm t$

On which axis should time be displayed when graphing motion?

• x-axis

• y-axis
