A pendulum ball of mass m is attached to the ceiling by a thin wire of length L. The ball moves at constant speed in a horizontal circle of radius R, with the wire making a constant angle beta with the vertical. The tension in the wire Select one: O A. is less than mg. O B. is greater than mg. O C. not enough information given O D. is equal to mg. O E. is any of the above, depending on the ball's speed v.
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
