Question

multiple choice If an object is moving, the amount of kinetic energy it has directly depends upon which of the following factors?
a the object's shape
b the object's mass
c the object's density
d the object's velocity

Answer 1

hint:
the formula of the kinetic energy KE of an object, is:
\[KE = \frac{1}{2}m{v^2}\]
where m is the mass of the object, and v is its speed

Answer 2

it is a and c am i riiht

Answer 3

I think b, and c since the mass is proportional to the density of the object.
Furthermore, we can say that the KE is a quadratic function of the velocity v

Answer 4

thnx your so awesome

Answer 5

thanks! :)
