Gravity

Front

What happens to objects without gravity?

Back

They would float away.

Front

How does mass change when moving from Earth to the Moon?

Back

Mass remains the same; it does not change.

Front

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

Back

Because the Moon has less mass and therefore less gravity.

Front

Is weight affected by gravity?

Back

Yes, weight depends on the force of gravity acting on an object.

Front

What is the one quantity that never changes regardless of location in the universe?

Back

Mass.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies toward each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass.

Front

How does gravity affect the motion of objects?

Back

Gravity causes objects to accelerate towards the center of a mass, such as a planet.

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 9.81 m/s².
