Newton’s 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) Responses magnetic force magnetic force electrostatic force electrostatic force friction force friction force strong nuclear force
The correct response is friction force.
is this right
Yes, that is correct. Friction force can decrease the total momentum of the system by acting in the opposite direction to the motion.
The force that can decrease the total momentum of the Newton's cradle system is friction force.
Friction is a force that opposes the relative motion between two surfaces in contact. In the case of Newton's cradle, when the balls collide, there is a transfer of momentum from one ball to the other. However, some of this momentum is lost due to the presence of friction.
Friction between the metal balls and the frame, as well as between the balls themselves, can cause a decrease in the overall momentum of the system. This can be observed as the swinging gradually slows down and eventually comes to a stop. The energy loss due to friction is typically converted into heat.
Therefore, friction force is the type of force that can decrease the total momentum of a Newton's cradle system.
