What is the main difference between a vector and a scalar?

• Vectors have units, scalars do not

• Vectors have direction, scalars do not

• Vectors are always positive, scalars can be negative

• Vectors are always larger than scalars

Which of the following is an example of a scalar quantity?

• 70 mph

• 10 m/s^2 downwards

• 5 N to the right

What is the relationship between distance and displacement?

• They are always the same

• Distance is always greater than or equal to displacement

• Displacement is always greater than distance

• They have no relation

A car travels 25 km on a curved road, but its displacement is 10 km to the right. Why is the displacement less than the distance?

• The car was moving slowly

• The road was not straight

• The measurement was incorrect

• Displacement is always less than distance
