Front

What does Newton's third law of motion state?

Back

For every action, there is an equal and opposite reaction.

Front

State Newton's first law of motion.

Back

An object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an external force.

Front

What is an example of a physical change?

Back

Melting of ice.

Front

What is the difference between a physical and chemical change?

Back

Physical changes involve a change in form without changing chemical composition, while chemical changes involve a change in chemical composition.

Front

Describe the relationship between mass and weight.

Back

Weight is directly proportional to mass.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

What is an example of a chemical change?

Back

Rusting of iron.

Front

What happens to the mass of an object when it is moved to a different location?

Back

The mass remains the same regardless of location.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Acceleration due to gravity (W = m x g).
