In what case would momentum be constant
WebQ. If two object collide and one is initially at rest (a) Is it possible for both to be at rest after collision. (b) Is it possible for any one to be at rest after collision. Ans. (a) No, because momentum will not be conserved in that case. (b) Yes, when masses of two object are equal and collision is perfectly elastic.

WebWhen thrown in an upward direction, a ball, during its throw, the ball momentum is first decreased, and then it starts increasing. In the earlier scenario, the ball’s momentum … Web10 mrt. 2012 · Either you need to include the Earth in the system and account for the transfer of momentum from the pendulum to the Earth or you have to consider the Earth as an external force. The former has no external forces and has a constant momentum, the later does not since gravity is an external force.

Web18 okt. 2013 · Professor walter lewin is correct. Let's do the elastic case. The ball momentum changes by -2mv. The momentum of the wall must change by 2mv due to momentum conservation. Assuming that the wall was initially at rest, the speed of the wall will be V w = 2mv/M w. It's kinetic energy will be K w = (1/2) M w V w 2 = (1/2) M w … cannings butcher kewWebMomentum is only conserved if the total external force is zero. If the system you consider is large enough, then any forces will be internal, not external. This is shown in the following cartoon, which is of course not to scale. A car accelerates from rest.
