What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that has the potential to be converted into kinetic energy.

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

How do you calculate potential energy?

Back

Potential energy (PE) can be calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

What is the relationship between kinetic energy and speed?

Back

Kinetic energy is directly proportional to the square of the speed of an object. As speed increases, kinetic energy increases exponentially.

What is the significance of the number of atoms in a chemical reaction?

Back

The number of atoms of each element must be the same on both sides of a chemical equation to satisfy the Law of Conservation of Mass.
