Gravitational Force Practice Flashcard

Front

What are the two factors that determine the strength of gravitational force between two objects?

Back

Mass and distance.

Front

Why doesn’t the Moon fall into Earth?

Back

The Moon’s forward motion balances Earth’s pull.

Front

Which of the following is an example of a contact force?

Back

Friction slowing a rolling ball.

Front

If the mass of one object is doubled while the other stays the same, what happens to the gravitational force between them?

Back

It doubles.

Front

How does increasing mass affect weight?

Back

Weight increases proportionally with mass.

Front

What is gravitational force?

Back

The attractive force between two masses.

Front

What is the formula for calculating gravitational force?

Back

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 their centers.

Front

What role does distance play in gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as weight = mass * gravitational acceleration.

Front

How does the gravitational force between two objects change if the distance is halved?

Back

The gravitational force increases by a factor of four.
