Is centripetal force a new force, explain?
Homework Answers
In circular motion or motion along any curved path, Newton's law is applied in two perpendicular directions, i.e., one along the tangent and other perpendicular to it, i.e., towards center. The component of net force towards center is called centripetal force. This centripetal force is necessary for any body moving in circular or curved path without which body will not be able to move in curved or circular path.
The centripetal force is given by:
where 
is speed of body
is radius of curvature
is angular speed of body

The direction of the centripetal force is always in the same direction a. as the centripetal acceleration vector b. as the velocity vector c. that an object would have if the centripetal acceleration suddenly stopped d. as the direction of motion of the object In this question, "constant in direction" refers to a fixed direction such as east or west. For uniform circular motion, the acceleration vector is a. changing in magnitude but constant in direction b. constant in magnitude...

Explain centripetal force? Think about the difference between uniform and non-uniform circular motion, examples and work done? If a ball of mass 0.5kg does a uniform horizontal circular motion of radius 5.0cm. If the velocity of the mass is 2.0 m/s what will be the tension force, centripetal force and period and frequency?

QUESTION 2 Remember that centripetal force and centripetal acceleration is the special name we give to the inwards force and acceleration that causes (forces) the object to move in a circle In the case of gravity where gravity causes a planet or satelite or star to orbit around another larger body, then gravity force is the centripetal force Centripetal force is the net force, and centripetal acceleration is the net acceleration. What is the centripetal acceler ation of a planet...

Wikipedia warns that the centripetal force is not to be confused with centrifugal force. It describes the latter as fictionious or inertial force. Decsribe an example of such a force that you have experienced and how this interaction might better be explained in terms of centripetal force.

Physics 1 One of the main topics this week is circular, or centripetal, motion looking at its acceleration and associated force. For the centripetal force, is this a NEW force, explain? Often times, CENTRIFUGAL force is used in describing circular motion, is this an appropriate alternative to centripetal force, explain? One example of centripetal force is its application to curves - flat & banked - in terms of the maximum speed one can make the curve, what happens when the...
