What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored within the chemical bonds of a substance, which can be released during a chemical reaction.

Front

What does Newton’s Second Law of Motion state?

Back

Newton’s Second Law of Motion states that acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is magnetic potential energy?

Back

Magnetic potential energy is the energy stored in a magnetic field, which can cause magnetic objects to move or change position.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, which can be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

How does height affect gravitational potential energy?

Back

The higher an object is positioned, the greater its gravitational potential energy, as it has more potential to fall due to gravity.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton’s Second Law, force equals mass times acceleration (F = ma), meaning more force is needed to accelerate a heavier object.

Front

What is an example of chemical potential energy?

Back

An example of chemical potential energy is the energy stored in food, which is released when the body metabolizes it.

Front

How can magnetic potential energy be observed?

Back

Magnetic potential energy can be observed when magnets attract or repel each other, causing movement without physical contact.
