A cheetah chasing an antelope increases its velocity to catch the antelope. Assuming the mass of the cheetah stays the same, what happens to the cheetah's kinetic energy as it increases velocity?

• As velocity increases, the cheetah's kinetic energy will increase.

• As velocity increases, the cheetah's kinetic energy will stay the same.

• As velocity increases, the cheetah's kinetic energy will decrease.

• It is impossible to tell because we don't know the mass of the cheetah.

• It is impossible to tell because we don't know the velocity of the cheetah.
