Orbit

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s²

Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r²

Front

What is the difference between mass and weight?

Back

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

Front

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

Back

The gravitational force is reduced to one-fourth.
