Speed and Velocity

Speed and Velocity

They seem the same but......

The video talks about scalars and vectors a lot...here is a poster to help you see the difference.

Multiple Choice

Which of the following measurements is considered scalar?

• Temperature

• Temperature Change

Multiple Choice

Which of the following measurements is considered a vector?

• speed

• velocity

Multiple Choice

Which of the following is considered a scalar measurement?

• volume

• weight

Multiple Choice

Speed is distance / time. Use the speed equation to solve the following problem... Janet walks 250 meters in 30 minutes. What is her speed in meters per minute?

• 8.3 meters/ minute

• 250 meters/ minute

• 30 meters/ minute

• 10.2 meters/ minute

Multiple Choice

Bill drove 54 miles in 45 minutes. How fast was he traveling in miles/ minute?

• 1.2 miles/ minute

• 55 miles per hour

• 1.2 mph

• 44 miles/ second

Multiple Choice

velocity equals displacement/ time. What is the velocity of a person who took the curviest roads possible to travel all the way west to Los Angeles (2000 miles) and it took them 72 hours to get there?

(velocity= displacement/ time)

• 27.8 miles/ hour

• 55 miles/ hour

• 144000 miles/ hour

• .036 miles/ hour

Multiple Choice

Which of these is considered a measurement of speed?

• 55 miles per hour west

• 55 miles per hour

Multiple Choice

which of these would be considered a measurement of velocity?

• 100 miles/ hour

• 100 miles/ hour south

Multiple Choice

Are distance and displacement the same thing?

• yes they mean the same thing

• No distance is the measurement of how far something has traveled and displacement is the measure of how far it ended up from the beginning point

Multiple Choice

After watching all the slides in this lesson: what is the velocity of a car travelling from Hagerstown to Washington DC (528 miles) if it takes 8.5 hours to get there?

• 62.1 miles per hour

• 62.1 miles per hour east
