Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids. Example: An egg cooking in a frying pan.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is highest when the object is at its highest point.

Front

Where is potential energy maximum in a vertical motion?

Back

At the highest point of the motion.

Front

What is kinetic energy (KE)?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases as mass increases, assuming velocity remains constant.

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What does a balanced chemical equation indicate?

Back

A balanced chemical equation indicates that the number of atoms of each element is the same on both sides of the equation.

Front

What is an example of a physical change?

Back

Melting ice is an example of a physical change, as it changes state but not chemical composition.

Front

What is an example of a chemical change?

Back

Burning wood is an example of a chemical change, as it transforms the wood into different substances.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.
