Impulse
force acting on an object over a period of time (I = F x t)
Impulse-momentum theorem
The impulse acting on an object is equal to its’ change in momentum
Momentum
The product of the mass and velocity of an object
Average force in Impulse
The impulse is equal to the average force multiplied by the time interval (p = Fav x t)
Conservation of linear momentum
The total momentum in an isolated system will remain constant (m1i v1i + m2i v2i = m1f v1f + m2f v2f)
Collision
The result of physical contact between two objects
Elastic collision
A collision where the total kinetic energy and momentum of an object is conserved
An isolated system
A system where no external forces have an influence on objects in the system
Inelastic collision
A collision where the total kinetic energy of an object is not conserved while the momentum of the object is.
