Fall Concept Review Flashcardziz

Front

What does F_e stand for?

Back

The electrostatic force.

Front

What has an eccentricity of zero?

Back

A circle.

Front

If two asteroids exert a gravitational force, F, on each other and are now three times as far apart, what represents the gravitational force at this distance?

Back

F/9.

Front

Which object has the MOST momentum if they are all rolling at the same velocity?

Back

Rolling bowling ball.

Front

Which configuration will result in the greatest gravitational force?

Back

Large masses close together.

Front

Define momentum in physics.

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

What is eccentricity in relation to conic sections?

Back

Eccentricity measures the deviation of a conic section from being circular; it ranges from 0 (circle) to 1 (parabola).

Front

How does distance affect gravitational force?

Back

Gravitational force decreases with the square of the distance between two masses.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the two masses.
