Circular Motion

Front

What type of interaction is a gravitational force?

Back

Attractive

Front

What is the universal gravitational constant (G)?

Back

The value of G is the same everywhere in the universe.

Front

What is the acceleration due to gravity (g)?

Back

The value of g varies with location.

Front

In uniform circular motion, the direction of the net force is:

Back

Directed toward the center of the circular path.

Front

What is the formula for centripetal acceleration (a_c)?

Back

a_c = v^2 / r, where v is the speed and r is the radius.

Front

If an object moves with a constant speed in a circle, what can be said about its acceleration?

Back

The object experiences centripetal acceleration.

Front

What is the relationship between centripetal force (F_c), mass (m), and centripetal acceleration (a_c)?

Back

F_c = m * a_c.

Front

What is the formula to calculate the centripetal force required for an object moving in a circle?

Back

F_c = (m * v^2) / r.

Front

What happens to the centripetal force if the speed of the object is doubled?

Back

The centripetal force increases by a factor of four.

Front

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

Back

Centripetal acceleration decreases.
