What is the main difference between speed and velocity?

• Speed is a vector quantity, while velocity is a scalar quantity.

• Speed has direction, while velocity does not.

• Speed only measures how fast an object moves, while velocity includes both speed and direction.

• Speed is always greater than velocity.

Which of the following is an example of velocity?

• 80 km/h

• 5 m/s west

• 30 m/min

• 100 mph

What is the correct formula for speed?

• Speed = Time / Distance

• Speed = Distance / Time

• Speed = Distance × Time

• Speed = Displacement × Time

How is speed represented on a distance-time graph?

• As a horizontal line

• As the slope of the graph

• As the area under the graph

• As a vertical line
