• Time

• Mass

• Velocity

What is a "gravity assist"?

• Any use of gravitational force that increases your net force (like swinging a mallet toward the ground).

• When an object (like a moon) orbits a planet and the Sun at the same time due to the planet's orbit.

• When a spacecraft enters and leaves a planet's gravitational sphere of influence to increase its velocity.

• When two large objects pull an object in the same direction with their gravitational forces, creating a greater net force than either individual gravitational force.
