PE Formula
The
formula for calculating
potential energy is mgh. The
three factors that determine
the amount of potential energy
in an object are mass,
gravitational acceleration, and
height of an object.
PE Measurements
PE = Joules
Mass = kg
Weight=Newtons
Gravitational pull = m/s2
Height = m

KE Definition
 Kinetic
energy is the energy of motion,
observable as the movement of an
object, particle, or set of particles.
KE Formula
KE=
½ . M . (v2 )
Two factors that determine KE in
an object are Mass and
Velocity
*reminder: velocity = speed

KE
 If
the mass has units of kilograms and the
velocity of meters per second,
 the kinetic energy has units of kilogramsmeters squared per second squared.
 Kinetic energy is usually measured in units
of Joules (J); one Joule is equal to 1 kg m2
/ s2
