review circular Motion and gravitational Force

Front

What happens to your mass if Earth's mass is cut in half?

Back

Nothing; mass is not affected by gravitational force.

Front

What is the relationship between centripetal force and the mass of an object?

Back

Direct relationship.

Front

In circular motion, where is the centripetal acceleration directed?

Back

Toward the center of the circular path.

Front

Which stars in Andromeda rotate the fastest?

Back

Stars furthest from the center.

Front

If the distance between two masses is doubled, what happens to the gravitational force?

Back

The force becomes F/4.

Front

Define centripetal force.

Back

The force required to keep an object moving in a circular path, directed toward the center of the circle.

Front

What is gravitational force?

Back

The attractive force between two masses.

Front

How does mass affect gravitational force?

Back

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

Front

What is the formula for gravitational force?

Back

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

Front

What is the effect of increasing the radius of a circular path on centripetal acceleration?

Back

Centripetal acceleration decreases.
