AP Physics 1 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

How does mass affect centripetal force?

Back

The centripetal force increases with the mass of the object; specifically, F_c = m * v^2 / r, where F_c is centripetal force, m is mass, v is velocity, and r is radius.

Front

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

Back

If the velocity triples, the centripetal force increases by a factor of 9, since F_c is proportional to the square of the velocity.

Front

What is the formula for centripetal force?

Back

F_c = m * v^2 / r, where F_c is centripetal force, m is mass, v is velocity, and r is radius.

Front

What is the relationship between radius and centripetal force?

Back

Centripetal force is inversely proportional to the radius; as the radius increases, the centripetal force required decreases for a given mass and velocity.

Front

What is the role of friction in circular motion?

Back

Friction provides the necessary centripetal force to keep an object moving in a circular path; without sufficient friction, the object may skid out of the path.

Front

How do you calculate the coefficient of static friction?

Back

The coefficient of static friction (μ_s) can be calculated using the formula: μ_s = F_f / F_n, where F_f is the force of friction and F_n is the normal force.

Front

What is the effect of increasing mass on centripetal force when radius is constant?

Back

If the radius is constant, increasing the mass of the object will result in an increase in the centripetal force required to maintain circular motion.

Front

What is the centripetal acceleration formula?

Back

Centripetal acceleration (a_c) is given by the formula: a_c = v^2 / r, where v is the velocity and r is the radius.

Front

What is the significance of the angle in circular motion problems?

Back

The angle can affect the components of forces acting on an object in circular motion, influencing the calculation of tension and centripetal force.
