Momentum Flashcards
1
Q
Momentum
A
The product of an objects mass and its velocity.
2
Q
Impulse
A
The product of the resultant/net force acting on an object and the time the net force acts on the object
3
Q
Principle of conversation of linear momentum
A
The total linear momentum of an isolated system remains constant (is conserved)
4
Q
Formula showing momentum is conserved in all collisions
A
m1.vf1 + m2.vf2 = m1.vi1 + m2.vi2
5
Q
Elastic collisions
A
Both momentum and kinetic energy are conserved
6
Q
Isolated system
A
A system in which the net external force is zero.
7
Q
Potential energy
A
Ep = mgh
8
Q
Kinetic energy
A
Ek = 1/2 mv^2
