Question

A student wants to determine the effect of mass on kinetic energy. She will drop two balls of the same size into a pool of water. Which investigation method should the student use?(1 point) Responses 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. She should drop two balls with different masses 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 of the same mass from different heights. She should drop two balls of the same mass from different heights.

Answer 1

The best investigation method for the student to determine the effect of mass on kinetic energy is: **She should drop two balls with different masses from the same height.**

This method allows the student to isolate the variable of mass while keeping the height constant, which ensures that any differences in kinetic energy observed upon impact with the water can be attributed solely to the differences in mass.
