Centripetal Force and Acceleration Concepts

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 direction of the centripetal force?

Back

Towards the center of the circular path.

Front

What is the formula for centripetal acceleration?

Back

a = v^2 / r, where 'a' is centripetal acceleration, 'v' is the linear velocity, and 'r' is the radius of the circular path.

Front

What is Newton's Law of Universal Gravitation?

Back

F = Gm₁m₂/r², where 'F' is the gravitational force between two masses, 'G' is the gravitational constant, 'm₁' and 'm₂' are the masses, and 'r' is the distance between their centers.

Front

Which object exerts the strongest gravitational force on you right now?

Back

The Earth.

Front

What does Newton's law state about two masses?

Back

Any two masses will attract each other.

Front

What is the relationship between centripetal force and mass?

Back

Centripetal force is directly proportional to the mass of the object moving in a circular path.

Front

What is the role of velocity in centripetal acceleration?

Back

Centripetal acceleration increases with the square of the velocity of the object.

Front

What happens to centripetal force if the radius of the circular path increases?

Back

If the radius increases, the centripetal force decreases for a constant speed.

Front

What is the effect of increasing speed on centripetal force?

Back

Increasing speed increases the centripetal force required to maintain circular motion.
