N2L: Fg Flashcard

Front

What forces are acting on a person standing on the surface of the Earth?

Back

Fg (force of gravity) and Fn (normal force)

Front

Why does a person weigh less on the Moon than on Earth?

Back

The Moon has less mass and therefore less gravity.

Front

In which direction does the force of gravity always point on Earth?

Back

Down

Front

Where will a 100kg person have a higher weight: on Earth (g=10m/s²) or Saturn (g=12m/s²)?

Back

Saturn

Front

Which planet has the strongest gravity in our solar system?

Back

Jupiter

Front

Define force of gravity (Fg).

Back

The force that attracts a body toward the center of the Earth, or toward any other physical body having mass.

Front

What is normal force (Fn)?

Back

The support force exerted upon an object that is in contact with another stable object.

Front

Explain the relationship between mass and weight.

Back

Weight is the force exerted by gravity on an object, which is directly proportional to its mass.

Front

What is the formula for calculating weight?

Back

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

Front

How does gravity vary on different planets?

Back

Gravity varies based on the mass and radius of the planet; more massive planets exert a stronger gravitational pull.
