Which of the following statements about speed and velocity is correct?

Only velocity includes the direction an object is traveling.

Speed and velocity both describe how an object is speeding up.

Speed describes how an object is changing its direction.

when a train increases its velocity its momentum

decreases

remains unchanged

increases

is transfered to its surroundings

increases after the collision

remains the same after collision

decreases after the collision

cannot be determined after the collision
