Forces and Motion Concepts

Front

What is the Law of Conservation of Matter?

Back

The Law of Conservation of Matter states that matter cannot be created or destroyed in an isolated system. The total mass of the reactants must equal the total mass of the products.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no net force and no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, resulting in a net force that causes a change in motion.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout, meaning that the different components are not distinguishable.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture in which the components are not uniformly distributed and can be easily distinguished.

Front

What are molecules?

Back

Molecules are groups of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Front

What factors affect speed?

Back

Speed depends on distance traveled and the time taken to travel that distance.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is force?

Back

Force is a push or pull acting upon an object, measured in Newtons (N). It can cause an object to accelerate, decelerate, or change direction.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in grams (g) or kilograms (kg).
