energy from power
linear/tangential velocity for circular motion
T is period= time for one complete circle
Instantaneous velocity
slope of the Tangent line Power rule forward (multiply by exponent then subtract one)
First kinematics equation (constant acceleration) no displacment
This is also average acceleration (slope of the second line of a velocity vs time graph)
Algebra: Definition of Center of Mass
Final velocity from acceleration vs time equation
area of acceleration vs time plus initial condition power rule backwards (add one then divide by exponent) + initial condition
Calculus: Definition of Moment of Inertia
Definition of Average Power (algebra)
Elastic Potential Energy for Hooke's Law spring
Work for rope falling off table
if lifting rope divide by 2
Rotational Inertia of disk: calculus
Parallel-Axis Theorem
What angle is max range off a cliff?
less than 45 degrees
Calculus: Definition of Center of Mass
Force of kinetic friction
depends on materials and normal force acting on object
Impulse-Momentum
velocity of center of mass
conservation of energy with friction
Finding force given potential energy as a function of position
Negative Sign!
Rotational Inertia of rod: Calculus
Calculus: Definition of Work
Hooke's Law
total acceleration
no angular acceleration
radial/ centripetal acceleration
Weight
depends on location and planet
Newton's Second Law, traditional
Definition of Angular momentum for point particle
conversion between translational displacement and angular displacement
Defining a Potential Energy
negative work
Newton's Second Law, calculus
Second kinematics equation (constant acceleration) no final velocity
most often used for projectile motion
average velocity
average velocity is the slope of the secant line
Newton's 3 Laws
Algebra: Definition of Moment of Inertia
Gravitational Potential Energy
Conservation of Mechanical energy
potential loss is kinetic gained
Dot Product
multiply parallel vectors then add for SCALAR answer=56 Joules
Force of static Friction
static friction is a variable force! Only as strong as it needs to be
instantaneous acceleration
Slope of the Tangent line power rule forwards (multiply by exponent then subtract one) 2nd derivative of position as a function of time
Definition of Instantaneous Power
Cross Product
use matrix to multiple perpendicular vectors to get a vector answer 3Nmi-6Nmj+3Nmk
tangential acceleration
Work-Energy Theorem
conversion for linear and angular velocity
angular momentum for system
Definition of Work (algebra)
angular acceleration definition (calculus)
Third kinematics equation (constant acceleration no time
Fourth Kinematics Equation (constant acceleration) no acceleration
Finding Position given velocity versus time equation
Area of velocity vs time plus initial position power rule backwards (add one and then divide by exponent) + initial condition
