Question

a collision in which kinetic energy decreases is called a(n) __________. * 1 point energy conservation elastic collision mechanical collision inelastic collision

Explanation:

• Energy conservation is a principle, not a type of collision.
• In an elastic collision, kinetic energy is conserved (does not decrease).
• There is no such standard term as "mechanical collision" in this context.
• In an inelastic collision, kinetic energy decreases (some is lost, e.g., as heat or sound).

Answer:

inelastic collision
