Distance vs Displacement and Speed vs Velocity

Select all quantities that are scalars.

• Speed

• Distance

• Displacement

• Time

• Position

The total length of the PATH of motion is best described as____.

• distance

• displacement

• motion

• donkey

The change in an object's position from the final position to initial position.

• displacement

• distance

• motion

• reference point

A man walks 5 miles east, 6 miles west and then 2 miles east. What is his displacement?

• 1 mile

• 13 miles

• 1 mile west

• 1 mile east

What is the main difference between distance and displacement?

• Distance is a vector quantity, while displacement is a scalar quantity.

• Distance is the total path covered, while displacement is the shortest path between two points.

• Distance is always equal to displacement.

• Displacement is always greater than distance.

Sara walks from Point A to Point B. Which is true?

• Distance and displacement are EQUAL

• Distance is less than displacement

Jermaine runs exactly 2 laps around a 400 meter track. What is the displacement?

• 800m

• 400m

• 0

• 200m

Vector quantities need both a magnitude and a _____.

• distance

• displacement

• direction

• velocity

Velocity is different from speed because...

• Velocity is distance/time. Speed is displacement/time.

• Velocity is speed in a certain direction and can be positive or negative.

• Speed is velocity in a certain direction. Both can only be positive.

• Velocity is how much speed changes over time.

The image shows two cars with the same speed moving in different directions. What is true about the velocity of the cars?

• Each car has the same velocity because the speeds are the same.

• Each car has a different velocity because they are going in different directions.
