Understanding Speed, Velocity, and Acceleration

How is velocity different from speed?

• Velocity is when an object goes in reverse.

• Velocity is the direction an object moves in, and it has nothing to do with speed.

• Velocity is speed and direction together.

• Velocity is not at all different from speed

Calculate the average speed (in meter/sec) if a cheetah runs 180 meters in 10 seconds.

• 198 m/sec

• 170 m/sec

• 12 m/sec

• 18 m/sec

What is the main difference between speed and velocity?

• Speed includes direction, while velocity does not.

• Velocity includes direction, while speed does not.

• Speed is always greater than velocity.

• Velocity is always greater than speed.
