Label the following diagram of Gravitational Force.
1: $m_1$, 2: $m_2$, 3: r, 4: F
Label the following diagram of Orbital Motion.
1: Central Body, 2: Orbiting Object, 3: Orbital Path
What happens when the distance between two objects increases?
The gravitational force between them decreases (inversely proportional to the square of the distance).
What happens when the mass of an object increases?
The gravitational force it exerts increases (directly proportional to the mass).
What happens when an object reaches escape velocity?
It breaks free from the gravitational pull of the celestial body.
What happens when the radius of an orbit increases?
The orbital velocity decreases, and the period of the orbit increases.
What are the differences between Circular and Elliptical Orbits?
Circular: Constant distance from orbiting object, constant speed. | Elliptical: Varying distance from orbiting object, speed varies.
