Universal Gravitation review

Front

What happens to the value of g on Earth's surface if Earth shrinks in size but keeps the same mass?

Back

The value of g increases.

Front

What does Newton's Law of Universal Gravitation affect?

Back

All objects with mass in the known universe.

Front

What is the Inverse Square Law?

Back

The force of attraction is inversely proportional to the square of the distance between two bodies.

Front

As the distance between two objects increases, what happens to the pull of gravity?

Back

The pull of gravity decreases.

Front

What causes ocean tides?

Back

Gravitational forces between the Earth and the moon.

Front

Define gravitational force.

Back

The attractive force between two objects with mass.

Front

What is the formula for gravitational force?

Back

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 the centers of the two masses.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with greater mass.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.
