Physics equations Flashcards
equation for kinetic energy
KE = ½mv^2.
equation for momentum
p = m x v
equation for density
d = m ÷ v
equation for pressure
p = f ÷ a
equation for acceleration
a = v-u ÷ t
equation for weight
w = m x g
equation for gravitional potential energy
Ep = mgh
Atom
smallest particle of an element
what do the periods tell us
how many shells there are
what do the groups tell us
how many electrons there are in the last shell.
equation for moment
force x distance from the pivot
symbol for moment
Nm - Newton - meters
The energy stored when repelling poles have been pushed closer together or when attracting poles have been pulled further apart.
Magnetic
The total kinetic and potential energy of the particles in an object, in most cases this is the vibrations - also known as the kinetic energy - of particles. In hotter objects, the particles have more internal energy and vibrate faster.
Thermal
The energy stored in chemical bonds, such as those between molecules.
