Conservation of Momentum Flashcards
1
Q
Conservation of momentum
A
For a system of interacting objects, the total momentum in a certain direction remains constant provided no external forces act on the system.
2
Q
when two objects collide what happens to momentum, total energy, and kinetic energy?
A
momentum and total energy are conserved.
If the collision was perfectly elastic, then kinetic energy is conserved;
else if the collision was inelastic. then kinetic energy is not conserved

Q
When two or more objects collide, there is a…
A
transfer of both momentum and kinetic energy
