Momentum Flashcards
Linear Momentum
the product of the mass and velocity of the object
Conservation of linear momentum
The total linear momentum of an isolated system remains constant (is conserved)
Elastic collisions
collision in which both momentum and kinetic energy are conserved
Inelastic collision
a collision in which only momentum is conserved
Impulse
product of the net force and the contact time
Newton’s Second law in terms of momentum
The net force acting on an object is equal to the rate of change of momentum.
Newton’s Third law
When object A exerts a force on object B, object B simultaneously exerts an oppositely directed force of equal magnitude on object A.
Gravitational potential energy
The energy an object possesses due to its position relative to a reference point.
Kinetic energy
The energy an object has as a result of the object’s motion.
Mechanical energy
The sum of gravitational potential and kinetic energy at a point.
Law of conservation of energy
The total energy in a system cannot be created nor
destroyed; only transformed from one form to another.
Principle of conservation of mechanical energy
In the absence of air resistance or any external forces, the mechanical energy of an object is constant.
