All Flashcards
What is the definition of Gravity?
The attractive force between objects with mass.
What is the definition of Orbit?
The path an object takes around another object in space.
What is the definition of Elliptical Orbit?
An oval-shaped orbit, not a perfect circle.
What is the definition of Orbital Velocity?
The speed needed to maintain a stable orbit.
What is the definition of Escape Velocity?
The minimum speed to break free from a celestial body's gravity.
What is the definition of Period?
The time for one complete orbit.

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.
