Momentum and Energy Flashcards
Collision
when two objects come into contact with each other; one or more objects exerting a force on each other
Elastic Collision
a collision in which two objects bounce off each other (momentum and energy are conserved)
Inelastic Collision
a collision in which two objects stick together after colliding (only momentum is conserved)
Elastic
ability for material to bounce back after being disturbed
Energy
the ability to do work
Elastic Potential Energy
the energy available for use when a deformed elastic object returns to its original configuration
Gravitational Potential Energy
the potential energy of an object due to its position in a gravitational field
Kinetic Energy
the energy of an object that is due to the objects motion
Potential Energy
the energy associated with an object because of the position, shape, or condition of the object
Impulse
the product of the force and time over which the force acts on an object
Joule
the unit for work and energy
Law of Conservation of Energy
energy cannot be lost or consumed, but can be transferred or transformed within (or between) objects
Law of Conservation of Momentum
states that the total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects
Linear Motion
motion in a straight line (one dimension)
Momentum
a quantity defined as the product of the mass and velocity of an object
