I have a question on my homework that says.... A scooter moving 10km/h has______ kinetic energy than a motorcycle moving the same speed. And for an answer, I put "the same" Is that right?

No! The formula for the kinetic energy a body possesses is:
K E = ½ m v ².
So, given the objects are moving with the same velocity, the more massive object will have more kinetic energy than the other. So, in this case, the motorcycle will have more kinetic energy than the scooter.

I think the answer is "less" a motorcylce is bigger and weighs more than a scooter so I think a scooter would have less kinetic energy even moving at the same speed.

The motorcycle would have more because it has more mass.
