Momentum (11) Flashcards
1
Q
Momentum, ρ
A
the product of mass and velocity. The unit is kgms-1. Conserved in both elastic and inelastic collisions.
2
Q
Principle of conservation of energy
A
states that energy cannot be created or destroyed, but it can be transferred from one type of energy to another.
3
Q
Impulse
A
the product of force and time. Unit is Ns.
4
Q
Linear momentum
A
the momentum of an object that moves only in one dimension.
5
Q
Conservation
A
the total momentum of two bodies in a collision (or explosion) is the same after the collision (or explosion) as it was before.
6
Q
Elastic
A
in elastic collisions kinetic energy is conserved.
7
Q
Inelastic
A
in inelastic collision kinetic energy is not conserved. Some or all of the kinetic energy is transferred to heat or other types of energy.
