Kinematics
Acceleration
The rate at which velocity changes
Newtons First law
A body at rest stays at rest and a body in motion stays in motion unless acted on by a net external force.
Definition of Momentum
Quantity of motion of a moving body
Kinetic energy
Energy possessed by being in motion
Tangent to the circle
Displacement
The change in position of an object.
Dynamics Definition
Study of forces that cause objects and systems to move
Elastic Collision
Conserves Kinetic Energy and doesn't stick
Potential Energy
Energy possessed due to position relative to others
Omega
Rotational Velocity
Gravitational Acceleration Constant
9.8m/s2
Tension
Force carried by a flexible medium
Impulse
Change in Momentum produced by the force in the time interval
Law of Conservation of Energy
Total energy may change form or be transferred from one system to another but the total remains the same
Is rotational kinetic energy a vector
Slope of a Velocity vs. Time Graph
Acceleration
Newtons 3rd law
Every action has an equal and opposite reaction
Inelastic Collision
Kinetic Energy is not preserved and objects stick together
Work Energy Theorem
W=1/2mv2-1/2mv02
Torque
Rotational Equivalent of a linear force,
A ball is dropped off a 30 meter cliff, assuming it falls freely, how long does to take to hit the ground?
2.5 seconds
Newtons 2nd Law
F=MA
Internal Kinetic Energy
Total sum of systems kinetic energy
Spring Constant
K=-f/x
Angular cylinder about cylinder axis
I=M/R(R21+R22)
