This type of energy is stored in an object due to position or arrangement.
What is potential energy?
The formula for calculating kinetic energy involves mass and this variable.
What is velocity?
The formula for gravitational potential energy includes mass, gravity, and this variable.
What is height?
This process involves the transfer of heat through direct contact between materials.
What is conduction?
This is the amount of heat required to raise the temperature of 1 kg of a substance by 1°C.
What is specific heat?
The process of converting energy from one form to another, such as from chemical to thermal.
What is energy transformation?
If an object has a mass of 2 kg and is moving at 3 m/s, its kinetic energy is this value.
What is 9 Joules?
A 10 kg object at a height of 5 meters has this amount of potential energy.
What is 490 Joules?
The transfer of heat through the movement of fluids is known as this.
What is convection?
Water has a specific heat of approximately this value in J/(kg·°C).
What is 4,186 J/(kg·°C)?
This law states that energy cannot be created or destroyed, only transformed.
What is the law of conservation of energy?
Doubling the speed of an object increases its kinetic energy by this factor.

This type of potential energy is stored in a compressed spring.
What is elastic potential energy?
This type of heat transfer occurs through electromagnetic waves and does not require a medium.
What is radiation?
If 500 J of heat is added to 2 kg of a substance with a specific heat of 1 J/(kg·°C), its temperature increases by this amount.
What is 250°C?
In a hydroelectric dam, gravitational potential energy is transformed into this type of energy.
What is kinetic energy?
This unit is used to measure energy, including kinetic energy.
