Eccentricity & Gravity Review

Front

What is eccentricity?

Back

A measurement of how elliptical an orbit is.

Front

What is the maximum eccentricity an ellipse can be?

Back

1

Front

If an orbit has an eccentricity value of '0', what shape is it?

Back

Perfectly circular.

Front

Which diagram shows a planet with the least eccentric orbit?

Back

Diagram 1.

Front

What does the strength of gravity between two objects depend upon?

Back

Mass & distance.

Front

What is the eccentricity of a perfectly circular orbit?

Back

0.

Front

What is the eccentricity of a highly elongated ellipse?

Back

Close to 1.

Front

How does distance affect gravitational force?

Back

As distance increases, gravitational force decreases.

Front

What is the relationship between mass and gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

What shape does an orbit with an eccentricity of 0.5 resemble?

Back

An elongated ellipse.
