A student is calculating the kinetic energy of a pendulum with different masses. What should the student conclude about the relationship between kinetic energy and mass?
If the mass of the pendulum increases, kinetic energy will decrease.
If the mass of the pendulum increases, kinetic energy will not be affected.
If the mass of the pendulum increases, kinetic energy will increase as well.
A student is calculating the kinetic energy of a pendulum moving at different velocities. What should the student conclude about the relationship between kinetic energy and velocity?
If the velocity of the pendulum increases, kinetic energy will increase as well.
If the velocity of the pendulum increases, kinetic energy will not be affected.
If the velocity of the pendulum increases, kinetic energy will decrease.
