LECTURE 6
questions after lecture
first try these again
now think about these
- Why are direction and mass both necessary components of a quantity of motion which is to be used in analysing collisions?
- What happens when a moving steel ball hits an equal steel ball at rest?
- What happens when a moving steel ball hits a larger steel ball at rest?
- What happens when a moving steel ball hits a smaller steel ball at rest?
- How does the equation which defines momentum (p=mv with arrows over p and v) indicate that momentum shows the flow of motion?
- In a collision, momentum is conserved. Express that in terms of transfer and flow of quantity of motion.
- What is an invariant?
- What is a symmetry law?
