AP Physics 1 Test Uniform Circular Motion & Law of Gravitation

Front

What happens to the gravitational force when the mass of an object is doubled?

Back

The gravitational force becomes 2 times stronger.

Front

What constant is the same everywhere in the universe?

Back

G (the gravitational constant).

Front

In uniform circular motion, where is the net force directed?

Back

The net force is directed toward the center of the circular path.

Front

If the force of gravity is reduced by 1/4, what could be a possible reason?

Back

The distance was doubled.

Front

What is the formula for centripetal acceleration?

Back

a = v²/r, where v is the speed and r is the radius.

Front

What is the relationship between gravitational force and distance?

Back

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

Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r².

Front

What is the unit of gravitational acceleration (g)?

Back

m/s² (meters per second squared).

Front

What is the value of gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

What is uniform circular motion?

Back

Motion in a circular path at a constant speed.
