Can you calculate the gravitational potential energy of a pendulum?

the pendulums gravitational energy refers to the gravitational energy of the bob (the string is considered to be mass less) the energy calculated for practical purposes is considering the mean position of the pendulum as the state of zero energy. but aesthetically the gravitational (potential) energy of a body only depends on its distance from the centre of the earth. the energy is equal to (gravitational constant(G))*(mass of earth)*(mass of bob) /(distance of bob from earths centre)

Where in the pendulum is gravitational potential energy highest?
at both ends of the swing, where the bob is the highest
A pendulum has a kinetic energy of 65 J and a gravitational potential energy of 78 J. What is its mechanical energy?
The mechanical energy is the sum of the two.
What type of energy conversion occurs in a pendulum?
It oscillates between gravitational potential energy at the top of it's swing to kinetic as it moves and back to gravitational energy on the opposite side.
Why does a pendulum in motion never swing to a greater height than it started?
This is a conservation of energy problem. When the pendulum starts out, it has gravitational potential energy; at the bottom of the swing, all of that has been converted to kinetic energy, and when it swings back up, back to gravitational potential energy (which is why speed is greatest at the bottom of the pendulum); in other words, there has to be the same amount of energy (PEgravitational = mass*gravity*height), where mass and gravity are constant.
Pendulum has a gravitational potential energy of 224 J when it is at its highest point At the lowest point in its swing it has a velocity of 4 ms What is the mass of the pendulum?
28 kg
What happens to the gravitational potential energy as the pendulum starts back up towards its highest point?
The pendulum's momentum or kinetic energy is converted to gravitational potential energy until all of the kinetic energy is converted. The pendulum stops.
A pendulum is designed to transfer potential gravitational energy into what?
When the bob of the pendulum while moving stops at one, its Kinetic energy changes completely into potential energy and when it starts its motion again, the potential energy changes to the kinetic energy
A pendulum is designed to transfer potiential gravitational energy into?
A pendulum transfers potential gravitational energy (at the top of its swing) to kinetic energy (movement at the bottom of the swing) and then back again (at the top on the other side).
Where in the pendulum is gravitational potential energy highest?
at both ends of the swing, where the bob is the highest

Does gravitational acceleration calculate potential energy?
Gravitational potential energy describes how much energy a body has in store by virtue of having been elevated to a specific height. The formula to calculate gravitational potential energy is:.U = mgh.Where:U is the potential energym is the mass of the objectg is the acceleration due to gravity, andh is the height the object will fall if dropped.
Where is a pendulum the fastest?
At the bottom of it's motion because the gravitational potential energy is zero

28 kg
What energy does pendulum transfer?
It converts gravitational potential energy (GPE) at the height of the swing to kinetic energy. This is then converted back to GPE. The process continues.
How would you calculate an objects gravitational potential energy?
Multiply its weight by its height.
