average velocity

average acceleration

velocity w/ constant acceleration

displacement curve equation (translation)

power rule

opposite of power rule

newton’s 2nd law

equation for kinetic friction

max of static friction

acceleration in a uniform circular motion

kepler’s first law

Dans le référentiel héliocentrique, les planètes du système solaire décrivent des trajectoires elliptiques, dont le Soleil occupe l’un des foyers.

kepler’s second law

Pendant des durées égales, le segment reliant le Soleil à une planète balaie des aires égales.

A1=A2 over ∆t

kepler’s third law

Le rapport du carré de la période de révolution par le cube du demi-grand axe est constant.

newtonian gravity

acceleration with newtonian gravity (free fall)

equations for work

kinetic energy (translation)

potential energy (gravitational for translation)

potential energy (spring for translation)

force exercised by a spring

non conservative system

can lose energy (heat/noise)

conservative system

doesn’t lose energy through work

equation for average power

impulse

J = change in momentum

momentum (and how it changes during collision)

elastic collision

all Ec of the object colliding w/ the other object is transfered to the other object

perfectly inelastic collision

Ec is not conserved, the objects move together

center of mass

average position of all the mass in the system

angular velocity

ω

tangential velocity

frequency

angular acceleration

radial acceleration

tangential acceleration

displacement curve equation (rotation)

angular velocity with angular acceleration

torque

τ

net torque

inertia

object’s tendency to keep doing what it’s doing

work of torque

rotational kinetic energy

angular momentum

equilibrium
