Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it possesses.

Front

What is a solid?

Back

A solid is a state of matter that has a fixed shape and volume, with particles that are closely packed together and vibrate in place.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another, often involving the formation of new substances.

Front

How does mass affect inertia?

Back

The mass of an object directly affects its inertia; greater mass means greater inertia, making it harder to change its motion.

Front

What is the difference between speed and acceleration?

Back

Speed is the rate at which an object moves, while acceleration is the rate of change of speed.

Front

What is the definition of a liquid?

Back

A liquid is a state of matter that has a definite volume but takes the shape of its container, with particles that are close together but can move past one another.

Front

What happens to the mass of an object when it breaks?

Back

The mass of an object remains the same even if it breaks; it is still the total mass of all the pieces combined.

Front

What is the definition of gas?

Back

A gas is a state of matter that has no fixed shape or volume, with particles that are far apart and move freely.

Front

What is an example of a physical change?

Back

An example of a physical change is melting ice into water; the substance changes form but not its chemical composition.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it is conserved.
