Answer to Problem 1ASA

Centripetal force is the force acting on an object executing rotational motion and it is directed towards the center of the rotational path.

Explanation of Solution

The force which is responsible for keeping any object undergoing rotational motion, in the circular path is called the centripetal force. It is acting towards the center of the circular path and simply it can be stated that the centripetal force is responsible for the rotational motion.

Any object under rotation will have a centripetal force which is provided by the field in which it is moving. For a planet revolving around the sun, the centripetal force is provided by the gravitational force of attraction between the Sun and planet. For an electron revolving around the nucleus of an atom, the centripetal force is provided by the electrostatic force. The centripetal force always directed towards the center of the circular path.

Examine the data and % error values in Data Table 3 where the angular displacement of the simple pendulum decreased but the mass of the pendulum bob and the length of the pendulum remained constant. Describe whether or not your data shows that the period of the pendulum depends on the angular displacement of the pendulum bob, to within a reasonable percent error.
In addition to the anyalysis of the graph, show mathematically that the slope of that line is 2π/√g . Using the slope of your line calculate the value of g and compare it to 9.8.
An object is placed 24.1 cm to the left of a diverging lens (f = -6.51 cm). A concave mirror (f= 14.8 cm) is placed 30.2 cm to the right of the lens to form an image of the first image formed by the lens. Find the final image distance, measured relative to the mirror. (b) Is the final image real or virtual? (c) Is the final image upright or inverted with respect to the original object?
