Gravity and Tides

Front

What is gravity?

Back

Gravity is the force of attraction between all things that have mass.

Front

What happens to gravitational force as mass increases?

Back

As mass increases, the gravitational force increases.

Front

Which object has the strongest gravitational pull based on mass?

Back

The Sun has the strongest gravitational pull based on mass.

Front

What is a spring tide?

Back

A spring tide occurs when the sun, Earth, and the moon are nearly in a line.

Front

What is a neap tide?

Back

A neap tide occurs when the sun and moon are at right angles relative to the Earth.

Front

What factors affect the strength of gravity between two objects?

Back

The strength of gravity is affected by the masses of the objects and the distance between them.

Front

What is the relationship between distance and gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, dependent on its mass.

Front

How does the gravitational pull of Earth compare to that of the Moon?

Back

Earth has a much stronger gravitational pull than the Moon due to its larger mass.

Front

What is the formula for gravitational force?

Back

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