Which term refers to the body's ability to absorb or reduce the kinetic energy of an object by applying negative force (e.g., catching a ball)?

• A. Streamlined
• B. Body type
• C. Angular velocity
• D. Absorption

Answer: (D)

Absorption is the body's ability to absorb or dissipate kinetic energy by applying a braking force opposite to the motion. When you catch a ball, you act like a shock absorber: you bend the knees and flex the arms so the impact time is longer. By increasing the time over which the ball's momentum is stopped, the peak force you experience is reduced, and the energy is absorbed through muscles, tendons, and joints, turning the moving energy into heat and stored elastic energy in tissues. This helps protect you from a hard jolt and allows you to stop safely. Other ideas describe different things: streamlined refers to a shape that reduces drag, body type describes physical build, and angular velocity is how fast something is rotating. These do not capture the ability to dissipate energy through a braking action like absorption does.
