Students are investigating two steel spheres with the same diameter. One sphere is solid and the other is hollow. The students hypothesize that the solid sphere is less likely to dent during a collision
than the hollow sphere. Both spheres must experience the exact same amount of force during the
collision so that the investigation is valid.
Which investigation makes both spheres experience the exact same amount of force during a
collision?
