SPEED and VELOCITY

Multiple Choice

What is the difference between speed and velocity?

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

• Speed describes how fast and which way an object is moving while velocity describes how fast an object is moving.

• Speed describes how fast an object is moving while velocity describes how fast and which way an object is moving.

• Speed has both magnitude and direction while velocity has magnitude only.

Multiple Choice

Is having a constant speed possible during your travel?

• Yes, but only when travelling in straight and curved roads.

• Yes, but very rare because during the travel, the vehicle may speed up or slow down.

• No, that is impossible to happen.

• No, because there is no such thing as constant speed.

Multiple Choice

What do you call the speed shown in the speedometer?

• Average Speed

• Velocity

• Instantaneous Speed

• Constant Speed
