What are some different forms of energy?

Chemical potential energy, Elastic, or strain, potential energy, Gravitational Potential Energy, Nuclear Potential Energy, Solar energy, Sound energy, Electrical energy

What is the law of the Conservation of energy

The law of Conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

What is the Conversion Of Energy?

The Conversion of Energy refers to the process of changing energy from one form to another, such as potential energy to kinetic energy.

What is an Energy Flow diagram?

An Energy Flow diagram is a visual representation that illustrates how energy is transferred and transformed in a system

What is efficiency?

Efficiency is the ratio of useful work done to the total energy input, often expressed as a percentage.

What is the formula for Efficiency?

Efficiency=Total Energy Input/Useful Energy Output​×100.

What is Potential Energy?

Potential Energy is the stored energy in an object due to its position or state, often related to the object's height.

What is the formula for Potential Energy?

PE=mgh where m is mass, g is the acceleration due to gravity, and h is height.

What is Kinetic Energy?

Kinetic Energy is the energy of an object in motion, dependent on its mass and velocity.

What is the formula for Kinetic energy?

KE=1/2 ​mv² where m is mass and v is velocity.

What is Work?

Work is the energy transfer that occurs when an object is moved over a distance by an external force.

What is the formula for Work Done?

The formula for Work Done is: W=Fd where F is force and d is distance.

What is a lever, and what does it do?

A lever is a simple machine that amplifies an input force to lift or move a load by using a fulcrum as a pivot.

What is effort?

Effort is the force applied to a lever or the input force required to perform work.

What is the formula for effort?

Effort= Load / Mechanical Advantage

What is a Pulley, and what does it do?

A pulley is a simple machine that consists of a wheel on an axle used to lift or lower loads with the help of a rope.

What are Gears?, and why are they important?

Gears are rotating mechanical components with teeth that transmit torque and change the speed or direction of motion.

What is the relationship between Work and Power?

Power is the rate at which work is done; it is calculated as Work done over time.

What is Power?

Power is the amount of energy transferred or converted per unit of time.

What is the formula for power?

The formula for power is: P=W/t. Where W is work done and t is time.
