An objects momentum depends on its

mass and it's velocity

Explanation:

Momentum can be defined as mass in motion. All objects have mass, so if an object is moving, then it has momentum which implies mass in motion. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
