Question

predicting changes in kinetic energy quick check
you are told 3 things...1. that there are two objects with equal masses. 2. both objects are in
motion. 3. one object has a greater kinetic energy than the other. how is this possible? (1 point)
one object has a greater speed than the other object.
one object is blue and one object is red.
one object has a greater volume than the other object.
one object has a greater density then the other object.

Explanation:

Kinetic energy formula is \(KE=\frac{1}{2}mv^{2}\). Given \(m_1 = m_2\), \(KE\) depends on \(v\). If \(v_1>v_2\), then \(KE_1>KE_2\). Color, volume, and density (when mass is same) do not affect kinetic energy in this context.

Answer:

One object has a greater speed than the other object.
