Collisions Flashcards
1
Q
Define a perfectly elastic collision.
A
A collision where both momentum and kinetic energy are conserved.
2
Q
Define an inelastic collision.
A
A collision where momentum is conserved by kinetic energy is not conserved.
3
Q
Define a perfectly inelastic collision.
A
A collision where momentum is conserved and the objects stick together after the collision.
4
Q
Define Linear momentum.
A
A vector quantity. P=mv where P is the momentum (kgms^-1), m=mass (kg), v=velocity (ms^-1).
5
Q
State the conservation of momentum.
A
In a closed system, the total momentum before a collision or event is the same as the total momentum after.
