Distance, displacement, speed and velocity

Which is true?

• Speed is measured in m/s but velocity is measured in s/m

• Speed is a vector and velocity is a scalar

• Speed and velocity are the same exact thing

• Speed is like velocity but without a direction

What is a difference between distance and displacement

• Distance is measured in seconds and displacement is measured in meters

• Distance is always shorter than displacement

• Displacement can be equal to zero if the object ends in the place it began in

• Distance can be equal to infinite when only a small distance has been travelled

An astronaut travels at a speed of 400 m/s for 250 seconds, what is the total distance he traveled?

• 0.625 m

• 100,000 m

• 1.6 m

• 650 m

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

• displacement
• distance
• motion
• reference point

Velocity is speed with __________________________.

• a unicycle helmet

• direction

• fight

A runner races in the 100 meter dash. It takes her 10 seconds to finish. What is her average speed?

• 10 m/s

• 1000 m/s

• 100 seconds

• 10 seconds

Joe rides his bike from point A to point B and then on to point C. What is the total distance traveled?

• 12 m

• 43 m

• 7 m

• 12 m

What is the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d

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

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction
