Centripetal Force

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

What is the formula for calculating centripetal force?

Back

The formula for centripetal force (F_c) is F_c = (m * v^2) / r, where m is mass, v is velocity, and r is the radius of the circular path.

Front

What unit is used to measure centripetal force?

Back

The unit for centripetal force is Newton (N).

Front

How does decreasing the radius of a turn affect speed?

Back

Decreasing the radius when making a turn allows you to keep a higher speed due to increased centripetal force.

Front

What happens to centripetal force if the velocity of an object increases?

Back

If the velocity of an object increases, the centripetal force required to maintain circular motion also increases.

Front

What role does friction play in centripetal force?

Back

Friction provides the necessary centripetal force to keep an object moving in a circular path, preventing it from sliding outward.

Front

In a circular motion, what direction does the centripetal force act?

Back

Centripetal force always acts towards the center of the circular path.

Front

What is the relationship between mass and centripetal force?

Back

Centripetal force is directly proportional to the mass of the object; as mass increases, centripetal force increases.

Front

If a car is rounding a bend, what happens if the driver takes their hands off the steering wheel?

Back

If the driver takes their hands off the steering wheel, the car will continue in a straight line due to inertia, not following the curve.

Front

What is inertia in the context of circular motion?

Back

Inertia is the tendency of an object to resist changes in its state of motion; in circular motion, it causes the object to move in a straight line if not acted upon by centripetal force.
