In the figure below, a steel bar sitting on two parallel metal rails, connected to each other by a resistor, is pulled to the right with a constant force of magnitude F = 1.15 N. The friction between the bar and rails is negligible. The resistance R = 8.00 N, the app bar is moving at a constant speed of 2.15 m/s, the distance between the rails is {, and a uniform magnetic field B is directed into the page. R Fapp (a) What is the current through the resistor (in A)? A (b) If the magnitude of the magnetic field is 2.70 T, what is the length { (in m)? m (c) What is the rate at which energy is delivered to the resistor (in W)? W

Angular speed, acceleration and displacement

Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.

Angular Position

Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
