Which of the following is TRUE about velocity? a if velocity changes the object could be speeding up
b if velocity changes the object could be slowing down
c an object with constant velocity is at rest
d Constant velocity is velocity that doesn’t change
e if velocity changes it is accelerating

D) constant velocity is velocity that doesnt change.

its not a, because if it changes you dont know for sure whether or not its speeding up or slow
ing down. its not always going to be speeding up.

its not b either for the same reason, but because its changing doesnt mean that its just speeding/slowing down

not e either since acceleration is different from velocity, you use velocity to find acceleration but this is just wrong.

hope this helped:)

The answer would be a
