A ball falls from a shelf. Assuming there is no friction, why is the conservation of mechanical energy independent of mass? (1 point)
Mass is eliminated when equating gravitational potential energy with kinetic energy.
• The displacement of the ball is insignificant compared with Earth's size.

Mass is eliminated when equating gravitational potential energy with kinetic energy.
Reason: mgh = 1/2 mv^2, so the mass m cancels, making the motion (e.g. final speed) independent of the ball’s mass.
