This energy calculator finds kinetic energy or gravitational potential energy.

It uses KE = ½mv² for moving objects and GPE = mgh for objects raised above a height.

The working panel shows the formula, substituted values and final rounded answer in joules.

Canonical folder: /energy-calculator/

Choose kinetic energy or gravitational potential energy on Page 1.

For KE, enter mass and speed. For GPE, enter mass, height and gravity.

Press SOLVE to calculate the answer and show the working.

Use EXAMPLE to restore the sample values, or CLEAR to reset the tool.

Use kilograms for mass, metres per second for speed and metres for height.

For GPE, gravity should be in m/s². Many GCSE questions use 9.8 or 10.

Energy is shown in joules when all input units are consistent.

For kinetic energy, remember that speed is squared before multiplying.

Students use this page for GCSE physics, combined science and mechanics homework.

Teachers and tutors can use it to show formula substitution and unit-safe working.

It is useful for energy stores, moving objects, falling objects and raised objects.

The calculator stays on Page 1 so the working tool is always quick to reach.

People may search for energy calculator, kinetic energy calculator, GPE calculator or gravitational potential energy calculator.

Other searches include KE equals half m v squared, GPE equals mgh, and energy formula with working.

This page supports those searches with a working calculator, formula help and readable internal pages.

GCSE users may search for physics energy calculator, kinetic energy GCSE or potential energy formula help.

Homework searches may ask how to calculate joules from mass and speed, or how to calculate energy from height.

The calculator answers these tasks by showing the formula, substituted values and rounded final result.

What is KE? Kinetic energy is energy stored by a moving object.

What is GPE? Gravitational potential energy is energy from height.

What unit is energy? Energy is measured in joules, written J.

What value for g? Use 9.8 m/s² unless your course asks for 10.

Why is my KE answer wrong? Check that speed is squared before multiplying.

Can I use decimals? Yes. Decimal mass, speed, height and gravity values are supported.

Does rounding affect working? Rounding is applied only to the final displayed answer.

Can it rearrange formulas? This page calculates energy from the direct KE and GPE formulas.

Energy connects to power, work done, force, speed, mass, height and gravity questions.

Related searches include mass speed energy calculator, mass height gravity calculator and joules calculator.

This page is designed for users who need a fast answer, a visible formula and clear working.

It covers calculation intent, revision intent, homework intent and formula substitution intent.

The support text is split across full-size reading panels instead of compressed SEO boxes.

Use kinetic energy to compare moving objects with different masses and speeds.

Use gravitational potential energy to calculate energy gained when an object is lifted.

For exam answers, write the formula, substitute the values, calculate, then add joules.

NEXT loops back to Page 1 so you can calculate another energy value.
