Gravity, Mass, & Distance

Front

What is gravity?

Back

Gravity is the force of attraction between two or more masses.

Front

How does gravity on the Moon compare to gravity on Earth?

Back

Gravity is weaker on the Moon than on Earth.

Front

Why do planets orbit the Sun?

Back

Planets orbit the Sun because it is the most massive object in our solar system, exerting the greatest gravitational pull.

Front

What two factors affect the magnitude of the force of gravity between two objects?

Back

The two factors are mass and distance.

Front

What happens to gravitational force if the distance between two objects is halved?

Back

The gravitational force becomes four times stronger.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

How does distance affect gravitational force?

Back

As distance increases, the gravitational force decreases.

Front

What is the formula for gravitational force?

Back

The formula is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the gravitational pull of the Earth?

Back

The gravitational pull of the Earth is approximately 9.81 m/s².
