Impulse-Momentum Theorem
The impulse-momentum theorem states
that the change in momentum of an object
equals the impulse applied to it.
-Impulse = (final momentum) – (initial
momentum)
-Impulse is a vector quantity
and has the same direction as
the average force
-Momentum is equal to the
mass times the velocity of the
object
Newton's second law (F

(Momentum and Impulse Connection. (n.d.)).
Covered Concept
Impulse Momentum
from “Sunday Football game”

Linear Momentum and Newton’s Third Law
What is Linear Momentum?
When two or more bodies acts upon each
other their total momentum remains
constant provided no external forces are
acting
Concept covered Linear Momentum
from the movie
“
Hidden Figures
”
(n.d.).

Momentum Conservation Exemplified
Concept covered
Momentum Conservation
“Pro Tennis Game”
The conservation of momentum is
a fundamental concept of physics
along with the conservation of
energy and the conservation of
mass.
(n.d.).

ENERGY
Potential vs. Kinetic
Potential/Not in Motion
Kinetic/In Motion
Energy that is stored and held in readiness
Relation to the Environment
Potential energy is not relative to the
environment of an object
