What is mass?

Back

The measurement of how much matter an object is composed of.

Front

What does inertia refer to?

Back

How much an object resists change to its state of motion (or obeys Newton's first law).

Front

What does Newton's first law state?

Back

Objects in uniform motion will remain that way unless acted on by an unbalanced force.

Front

What is weight?

Back

A force that measures the gravitational pull on an object.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = m × g).

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.8 m/s².

Front

What is the relationship between mass and inertia?

Back

Inertia is directly proportional to mass; more mass means more inertia.

Front

What is an unbalanced force?

Back

A force that causes an object to change its state of motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is Newton's second law of motion?

Back

Acceleration is directly proportional to net force and inversely proportional to mass (F = m × a).
