Question

how is the kinetic energy of an object related to its mass?
○ kinetic energy must be less than an object’s mass for movement to occur.
○ kinetic energy decreases as mass increases.
○ kinetic energy increases as mass increases.
○ kinetic energy and mass must be equal for movement to occur.

Explanation:

The formula for kinetic energy is \( KE = \frac{1}{2}mv^2 \), where \( m \) is mass and \( v \) is velocity. Assuming velocity is constant, as mass (\( m \)) increases, kinetic energy (\( KE \)) increases because they are directly proportional. The first option is incorrect (KE and mass aren't about being less for movement). The second is wrong (KE should increase with mass). The fourth is incorrect (they don't need to be equal). So the correct relationship is that kinetic energy increases as mass increases.

Answer:

C. Kinetic energy increases as mass increases. (Note: Assuming the third option in the list is labeled as C; adjust label based on actual option numbering in the original question, but the content is "Kinetic energy increases as mass increases.")
