She should drop two balls of the same mass from different heights.
She should drop two balls of the same mass from different heights.

She should drop two balls of the same mass from the same height.
She should drop two balls of the same mass from the same height.

She should drop two balls with different masses from the same height.
She should drop two balls with different masses from the same height.

She should drop two balls with different masses from different heights.

Answer 1

The best investigation method for the student to determine the effect of mass on kinetic energy would be:

She should drop two balls with different masses from the same height.

This method allows her to keep the height constant so that the kinetic energy can be compared based solely on mass, eliminating the variable of changing gravitational potential energy due to different heights.
