If the centripetal force on an object in uniform circular motion is increased what is the effect on the frequency of rotation f(with r constant) and f and r when both are free to vary?
Is it possible for a car to move in a circular path in such a way that it has a tangential acceleration but no centripetal acceleration?
A tetherball swings in a horizontal circle. If the radius of the swing is increased 9 times but the tangential speed remains the same, by what factor does the centripetal force change?

- Circular orbits in Equation 13.10 for conic sections must have eccentricity zero. From this, and using Newton’s second law applied to centripeta acceleration, show that the value of in Equation 13.10 is given by Where is the angular momentum of the orbiting body. The value of is constant and given by this expression regardless of the type of orbit.arrow_forwardCheck Your Understanding Assume you are in a spacecraft in orbit about the Sun at Earth’s orbit, but far away from Earth (so that it can be ignored). How could you redirect your tangential velocity to the radial direction such that you could then pass by Mars’s orbit? What would be required to change just the direction of the velocity?arrow_forwardA geosynchronous Earth satellite is one that has an orbital period of precisely 1 day. Such orbits are sueful for communication and weather observation because the satellite remains above the same point on Earth (provided it orbits in the equatorial plane in the same direction as Earth’s rotation). Calculate the radius of such an orbit based on the data for Earth in Appendis D.arrow_forward
- Explain why centripetal acceleration changes the direction of velocity in circular motion but not its magnitude.arrow_forwardHow much centripetal force (in N) is required to keep an object with mass 2.5kg moving uniformly in a circle of radius 0.33m at a constant linear speed of 1.7m/s?arrow_forwardEven though an object can have a constant tangential speed, the acceleration of an object in circular motion can NEVER be ____________________. A. zero B. less than the value of the speed C. equal to the value of the centripetal force.arrow_forward
- A car, with mass m, is racing around a circular track with some velocity v. If the car suddenly had its mass tripled and velocity doubled, what would happen to the centripetal acceleration needed for the car to conitnue circular motion?arrow_forwardA planet orbits a star, in a year of length 2.77 x 107 s, in a nearly circular orbit of radius 3.78 x 1011 m. With respect to the star, determine (a) the angular speed of the planet, (b) the tangential speed of the planet, and (c) the magnitude of the planet's centripetal acceleration.arrow_forwardA bucket of water rotates in a vertical circular orbit with a radius of 1.6 m.
