Gravity

Front

What is mass and how does it relate to gravity?

Back

Mass is a measure of the amount of matter in an object. It does not change regardless of the gravitational field.

Front

What happens to the force of gravity as the distance between two objects increases?

Back

The force of gravity decreases as the distance between two objects increases.

Front

True or False: Any object with mass has its own gravitational pull.

Back

True.

Front

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

Back

A person weighs less on the Moon because the Moon has less mass and therefore exerts less gravitational force.

Front

When is the gravitational force between two objects the greatest?

Back

The gravitational force is greatest when both objects have large masses and are close together.

Front

Define gravity in the context of physics.

Back

Gravity is a 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 difference between mass and weight?

Back

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

Front

How does gravity affect the motion of objects in space?

Back

Gravity influences the orbits of planets, moons, and other celestial bodies, keeping them in motion around larger masses.

Front

What role does gravity play in the formation of planets and stars?

Back

Gravity pulls together gas and dust in space, leading to the formation of planets and stars.

Front

Explain the concept of gravitational fields.

Back

A gravitational field is a region of space around a mass where another mass experiences a force of attraction.
