Energy transformation Review

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

As a rollercoaster descends, gravitational potential energy is converted into kinetic energy. Some energy is also lost to the surroundings as heat and sound due to friction and air resistance.

When you are on a diving board, you have gravitational potential energy due to your height. As you jump and fall toward the water, this potential energy is converted into kinetic energy.

Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, or its electric charge. It is often referred to as stored energy.

Energy is defined as the capacity to do work, it follows the law of conservation (cannot be created or destroyed), and it is associated with movement. Therefore, all the provided statements are correct.

Food contains energy stored in the molecular bonds of nutrients. This stored potential energy is classified as chemical energy.

Energy conversion is the process of changing energy from one form to another, such as electrical energy turning into light energy in a bulb.

In a collision on a ramp, potential energy converts to kinetic energy. When the moving car hits the stationary car at the bottom, energy is transferred from the first car to the second - the first car loses some of its kinetic energy while the second car gains kinetic energy from the impact.

A higher starting position increases the potential energy of the car. As it rolls down, this becomes more kinetic energy, resulting in a greater transfer of energy upon impact.

When a phone rings, electrical energy is converted into sound waves. The sound produced is the observable evidence that energy has been transferred to the air.

Burning a match is a chemical reaction that releases energy. The visible flame provides light, which is evidence of the energy being released.

Batteries store chemical energy. When the flashlight is turned on, this chemical energy is converted into electrical energy, which then powers the bulb to produce light.

Kinetic energy is defined as the energy an object possesses due to its motion. Anything that moves has kinetic energy.

A toaster uses electrical energy from the wall outlet and converts it into thermal (heat) energy to toast the bread.

Batteries contain chemical substances that react to produce an electric current. Therefore, the energy stored within them is chemical potential energy.

An electric stove uses electrical energy to heat up the heating element, which then transfers that thermal energy to the food or pot.

Photosynthesis is the process where plants capture solar energy and store it in the chemical bonds of glucose (food).

Kinetic energy is the energy of motion. Potential energy is stored energy, and gravitational energy is a form of potential energy.

In physics, energy is defined as the capacity or ability to perform work, where work is defined as a force applied over a distance.
