How to find the kinetic energy of a pendulum?

cytochrome

The potential energy can be obtained with the equation

Fnet = ∇U

Where Fnet is the sum of all the forces acting on the pendulum.

How can we obtain kinetic energy when we don't know the mechanical energy or the velocity?

SHISHKABOB

the kinetic energy of the pendulum will be equal to the total energy minus the potential energy

the total energy of the pendulum is determined by how high up it is released
