Newtons 1st law of Motion
Object at rest stays at rest
Newtons 2nd law of Motion
(force)=(mass)(acceleration)
Newtons 3rd law of Motion
For every action there’s an equal and opposite reaction
Formula of Speed/Velocity
S=Distance/Time Unit -m/s / km/h
Definition of Acceleration
The rate at which on object’s velocity changes over time
Formula of Acceleration
A= Vf-Vi/T m/s/s
Uniform vs Non Uniform
Uniform = Acceleration that is constant over time
Non uniform = Acceleration that is not constant over time
Momentum Definition
The measure of how much motion an object has. It depends on mass and velocity
Formula of Momentum
momentum(p)=(mass)(velocity) kg*m/s
Definition of Energy
The ability to do work
Definition of Work
a measure of energy transfer that occurs when an object is moved over a distance by an external force
Formula for Work
(work)=(force)(distance) - Joules
Definition of Mechanical Energy
Energy that is possessed by an object due to its motion or position
Potential Energy Definition
Energy that is stored and held in readiness
Definition of Kinetic Energy
Energy of Motion
Formula of Kinetic Energy
KE= 1/2(mass)(velocity)^2 = Joules
Formula of Gravitational Potential Energy
GPE=(mass)(gravity/9.8)(height) - Joules
