Gravity Test Review Flashcardizz

Front

What is an equipotential line in a gravitational field?

Back

An equipotential line is a line where the gravitational potential is the same at all points, meaning the gravitational field strength is equal.

Front

How does the distance between two masses affect the gravitational force between them?

Back

The gravitational force decreases as the distance between the two masses increases, following the inverse square law.

Front

What does it mean when gravitational field lines are close together?

Back

When gravitational field lines are close together, it indicates a stronger gravitational field strength.

Front

What is the relationship between mass and gravitational attraction?

Back

The gravitational attraction between two masses increases with the mass of either object.

Front

What is the direction of the gravitational force acting on a planet in orbit?

Back

The gravitational force acting on a planet in orbit is directed towards the center of the star it is orbiting.

Front

What happens to the gravitational force between two objects if one object is moved further away?

Back

The gravitational force between the two objects will decrease if one object is moved further away.

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

Front

What is gravitational field strength?

Back

Gravitational field strength is the force per unit mass experienced by a small test mass placed in the field.

Front

What is the significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a proportionality factor used in the calculation of gravitational force between two masses.

Front

What does it mean for gravitational field lines to be far apart?

Back

When gravitational field lines are far apart, it indicates a weaker gravitational field strength.
