Energy Conversion

Energy conversion is the process of changing energy from one form to another. This transformation allows energy to be used in many ways, such as conve

The Law of Conservation of Energy states that energy cannot be created or destroyed—it can only be transformed from one form to another or transferred

Work is applying a force to an object, causing it to move in the direction of the applied force. In physics, work is only done when there is movement

Work is done when a force is applied to an object, and the object moves in the direction of the force. In physics, work is calculated by how much forc

Power is the rate at which energy is transferred, converted, or used over time. It is measured in watts (W), where one watt equals one joule of energy

Efficiency refers to how well energy, time, or resources are used to achieve a desired outcome with minimal waste. It is a key concept in various fiel

When a chemical reaction creates electricity, we’re seeing a change from chemical energy to electrical energy. This transformation happens in devices

When an object moves or experiences friction, its mechanical energy—energy due to motion or position—can be changed into thermal energy, or heat. This

When electrical energy is changed into light energy, we see it all around us — in lamps, flashlights, and even the screens on our phones. This process

A heating system is a setup that transfers energy to warm up spaces, water, or materials. The system works by converting one form of energy—often chem

A cooling system is a process or device that removes heat from an object or space to lower its temperature. They are designed to remove thermal energy

An inclined plane is a flat surface set at an angle, like a ramp. It helps move objects from a lower point to a higher one using less effort than lift

A wedge is a simple machine that helps us split, cut, or hold things apart by turning a force you apply into a force that pushes outward. You’ve proba

A screw is a simple machine that converts rotational motion into linear motion and increases force. It is basically an inclined plane wrapped around a

A lever is a simple machine that helps you move or lift objects using less effort. It consists of a rigid bar that rotates around a fixed point called

The wheel and axle is one of the six classic simple machines. It helps us do work by making it easier to move or lift objects. The wheel and axle work

A pulley is a simple machine that helps you lift or move heavy objects by using a wheel and a rope. When you pull on one end of the rope, the wheel ro
