What is the difference between velocity and speed?

• There is no difference.

• Speed is how fast and Velocity is how far.

• Speed is how fast and Velocity is how fast and in which direction.

• Speed is how fast and which direction and velocity is how fast.

• stop moving

• move in the same direction as the stronger force.

• unpredictable situation
