1.7 Linear Momentum & Impulse Flashcards
1
Q
Momentum
A
P= mv:
The product of a bodies mass and velocity
2
Q
The principle of conservation on linear momentum
A
In a closed system, TMB = TMA
3
Q
Elastic Collision
A
Kinetic energy is conserved, total energy is constant
4
Q
Inelastic collision
A
Kinetic energy is not conserved, but total energy is constant
5
Q
Totally inelastic collisions
A
Collisions in which two objects stick together, with a loss in kinetic energy. But total energy is constant
6
Q
Impulse
A
Impulse= F x t
The product of Force and time the force is applied.
7
Q
Define newtons 2nd law in yearns of momentum
A
The rate of change of momentum of a body is proportional to the applied force and acts in the same direction as the force
