N2L: Fg Flashcard

Front

What is the formula for calculating weight?

Back

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

Front

What is the gravitational acceleration on Earth?

Back

Approximately 10 m/s².

Front

What is the gravitational acceleration on Saturn?

Back

Approximately 12 m/s².

Front

What is the gravitational acceleration on Mercury?

Back

Approximately 4 m/s².

Front

If a person has a mass of 100 kg, what is their weight on Earth?

Back

Weight = 100 kg × 10 m/s² = 1000 N down.

Front

If a person has a mass of 70 kg, what is their weight on Earth?

Back

Weight = 70 kg × 10 m/s² = 700 N down.

Front

What does it mean for forces to be balanced?

Back

Balanced forces mean that the net force acting on an object is zero, resulting in no change in motion.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface.

Front

How does weight change when moving from one planet to another?

Back

Weight changes based on the gravitational acceleration of the planet; it is higher on planets with greater gravitational acceleration.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.
