In this Newton's cradle, one metal ball is pulled back, causing the other balls to move. Is this an elastic or inelastic collision and why? (1 point) Responses elastic, because kinetic energy and momentum are conserved within the system elastic, because kinetic energy and momentum are conserved within the system elastic, because all of the balls have the same mass elastic, because all of the balls have the same mass inelastic, because momentum is not conserved within the system inelastic, because momentum is not conserved within the system inelastic, because kinetic energy is transferred into sound and heat energy

Answer 1

The correct response is: elastic, because kinetic energy and momentum are conserved within the system.

In a Newton's cradle, the collisions between the balls are considered elastic because both momentum and kinetic energy are conserved during the interactions, assuming ideal conditions (no friction or energy loss). The characteristic behavior of the cradle demonstrates these conservation principles effectively.
