What is defined as motion?

• A change in speed

• A change in position

• A change in direction

• A change in acceleration

Which symbol is used to represent change?

• Σ

• Ω

• Δ

• π

What does Δx represent?

• Change in velocity

• Change in time

• Change in position

• Change in acceleration

Which of the following is a vector quantity?

• Velocity

• Time

• Temperature

• Displacement

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?

• 40 miles East

• 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

If you walk 4m East, 2m South, 4m West, and 2m North, what is your displacement?

• 12 m

• 8 m

• 4 m

• 0 m

In the football coach example, why is the displacement zero?

• The coach did not move

• The coach returned to the starting point

• The field is too short

• The displacement is always zero when running
