*force = mass x (velocity / time) = (mass x velocity) / time = momentum / time
*force x time = momentum
-difference between force and momentum is time.
F[1->2] = -F[2->1]
(Newton's Third law says that for a force exerted by object 1 on object 2, object 2 exerts a force on object 1 that is equal in magnitude and opposite in direction to the force object 1 exerts).

Velocity:  Speed of something in a specific direction.
V = D/T
Units: M/s, ft/s.... etc.
Acceleration: Increase in the rate of speed of an object.
A = (Change in Velocity / Time interval)
Units: M/s ^2, ft/s ^2.... etc.
Circular motion: Movement of an object along the circumference of a circle.
Distance/ Velocity/Acceleration graphs.

Momentum is a measurement of mass and velocity. All motion (a result of applied force) requires energy (p=mv), otherwise known as mass times velocity.

Energy can be transferred by forceful contact between two bodies - collisions. There is a range of 'elasticity' to describe these collisions. Inelastic (a system loses momentum - though it is conserved in unobserved objects) and Elastic (a system does not lose momentum - the momentum is fully transferred from one object to another, or is shared equally between the objects involved in the collision)

Potential energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

Kinetic energy is energy possessed by a body by virtue of being in motion.

Newton's first law states that an object in motion stays in motion, therefore the object in motion has kinetic energy.In addition, the law of inertia states that an object at rest stay in rest, meaning it possess potential energy.

F=ma
Applied Force- is force applied by a human or another object to an object.
Gravitational Force-gravity is defined as the weight of an object.
Fgrav= m * g g=9.8 N/kg and mass is in kg.
Normal Force- force exerted upon an object that is in contact with another stable object.
Frictional Force-force exerted by a surface as an object moves across it or makes an effort to move across it
Force has both has magnitude and direction.
Magnitude=((x^2)+(y^2))^(1/2)
Direction= tan^-1(x/y)

Newton's Second Law states that force is related to acceleration, as reflected in the equation F=m*a. This means that the more force applied to an object, the more it accelerates. This it true in multiple circumstances, including circular motion. In circular motion, an object constantly changes the direction of velocity, causing acceleration, and therefore, a force on the object in motion. This force is called centripetal force, which pulls the object towards the center. In addition to this, the net force in circular motion is equal to the centripetal force. Also, both forces and motion can be expressed in vectors. Both have direction and magnitude. Net force is equal to zero when an object is at rest or at constant velocity, meaning that all the forces have an equal force opposing it, cancelling each other out.

Can be centripetal or straight line.
Straight line:
p = mV
= F*deltaT
= ∫ m*a(dt)
F*delta T=Pf-Pi
Angular Impulse
L = I*W (W = angular velocity, I = resistance to motion)
Momentum is conserved in collisions. This can be expressed as P1i+P2i=P1f+P2f
Collisions can be characterized as elastic or inelastic, depending on if the objects separate.
For elastic collisions M1V1i +M2V2i = M1V1f + M2V2f
For inelastic collisions M1V1i +M2V2 =  (M1+M2)*Vf
