Question

newtons cradle is a contraption where metal balls hang from a frame. when one ball is pulled and released, the collision causes one ball on the opposite end to be released. which type of force can decrease the total momentum of this system? (1 point) magnetic force friction force electrostatic force strong nuclear force

Explanation:

Momentum is conserved in a closed - system. External non - conservative forces can change the total momentum. Friction is a non - conservative force that dissipates energy as heat and can decrease the total momentum of the Newton's cradle system. Magnetic, electrostatic, and strong nuclear forces are not relevant in this context as they do not act in a way to decrease the momentum of the balls in the typical operation of Newton's cradle.

Answer:

friction force
