Question

which piece of evidence collected during class supports your answer to #2. a laser was reflecting off of a piece of glass. when force was applied to the glass, the laser moved. when two spring scales were pushed together, the force reading on both objects was the same. we saw slow motion videos of objects colliding and showing changes in shape during the collision. we applied force to different materials (coffee stirrers and styrofoam) and measured the amount of deformation each material experienced.

Explanation:

The third option about two spring - scales being pushed together with equal force readings on both objects demonstrates Newton's third law of motion (action - reaction forces are equal and opposite). This is a key concept in physics experiments to show balanced forces in an interaction.

Answer:

When two spring scales were pushed together, the force reading on both objects was the same.
