Unit 9 Vocabulary

Front

What is the amount of matter in an object?

Back

Mass

Front

What is the term for a zone of weak gravity, such as when orbiting in a spacecraft?

Back

Microgravity

Front

What is the force exerted on an object by gravity?

Back

Weight

Front

What is the unit of measurement for mass in the metric system?

Back

Kilogram (kg)

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 happens to your weight in microgravity?

Back

Your weight appears to decrease because the force of gravity is weaker.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Gravity (W = m x g)

Front

What is the gravitational acceleration on Earth?

Back

Approximately 9.81 m/s²

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

What is the relationship between mass and inertia?

Back

Inertia is the resistance of an object to change its state of motion, and it is directly related to mass.
