we were assigned a few to find answers to, the following ones stumped me, hopefully you can help :)
When two objects of different masses collide and the collision is elastic, it is said that the two objects will always move off at right angles to each other.
Is this likely to be true? Explain
Can an object, perhaps in motion, receive an impulse without having work done on it?
Conversely, can an object have work done on it without receiving an impulse?
3) If a satellite in circular orbit around the Earth encounters the outer fringes of the atomosphere, it begins to lose energy through friction. Yet the result is that it increases speed, Why is this?
idea for 3) Is this because it Moves closer to the Earth and has a greater force of gravity acting upon it
