Chapter 1 - Momentum Flashcards
1
Q
Define perfectly elastic collision?
A
A collision is perfectly elastic when kinetic energy is conserved (momentum and total energy always conserved).
2
Q
Define inelastic collision?
A
A collision is inelastic when kinetic energy is not conserved.
3
Q
Momentum = ?
A
Mass x velocity (vector)
4
Q
Define the Principle of Conservation of Momentum?
A
Within a closed system, the total momentum in any specified direction remains constant.
Therefore:
Total momentum before collision = total momentum after collision
