What object was use as a ball in trackball by Tom Cranston Fred Long Staff Kenton Taylor?
In the original design of trackball by Tom Cranston, Fred Long, and Kenton Taylor, a Bowling ball was used as the object for the ball component. This choice provided a smooth, durable surface for the device's operation. The trackball concept allowed for more intuitive control in computer interfaces, paving the way for the development of modern pointing devices.

The three inventors used a bowling ball as the object in their trackball device. They created the trackball as part of a British Royal Navy radar system.

What is the difference between a mouse and trackball?
In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input. The mouse's motion typically translates into the motion of a cursor on a display, which allows for fine control of a graphical user interface.A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes-like an upside-down mouse with an exposed protruding ball. The user rolls the ball with the thumb, fingers, or the palm of the hand to move a cursor. Large tracker balls are common on CAD workstations for easy precision. Before the advent of the touchpad, small trackballs were common on portable computers, where there may be no desk space on which to run a mouse. Some small thumbballs clip onto the side of the keyboard and have integral buttons with the same function as mouse buttons. The trackball was invented by Tom Cranston and Fred Longstaff as part of the Royal Canadian Navy's DATAR system in 1952,[1] eleven years before the mouse was invented. This first trackball used a Canadian five-pin bowling ball. The world's first trackball invented by Tom Cranston, Fred Longstaff and Kenyon Taylor working on the Royal Canadian Navy's DATAR project in 1952. It used a standard Canadian five-pin bowling ball.When mice still used a mechanical design (with slotted 'chopper' wheels interrupting a beam of light to measure rotation), trackballs had the advantage of being in contact with the user's hand, which is generally cleaner than the desk or mousepad and does not drag lint into the chopper wheels. The late 1990s replacement of mouseballs by direct optical tracking put trackballs at a disadvantage and forced them to retreat into niches where their distinctive merits remained more important. Most trackballs now have direct optical tracking which follows dots on the ball.As with modern mice, most trackballs now have an auxiliary device primarily intended for scrolling. Some have a scroll wheel like most mice, but the most common type is a "scroll ring" which is spun around the ball. Kensington's SlimBlade Trackball similarly tracks the ball itself in three dimensions for scrolling.Three major companies Logitech, A4Tech, and Kensington currently produce trackballs, although A4Tech has not released a new model in several years. Microsoft was a major producer, but has since discontinued all of its products. The Microsoft Trackball Explorer continues to be extremely popular (it has no analogous design in production by another company), with used models selling for ~$200 on ebay.

What is the energy caused by the force of gravity on a rising object?
The gravitational potential energy is equal to U=-GM/r where G is the gravitational constant, M the mass of the object causing the force and r the distance from that object. Near the surface of the earth a good approximation of the potential energy is U=mgh (you can get it using the Taylor series of U=-GM/(R+r) where R is the radius of the earth) where m is the mass of the object the force acts on, g the acceleration due to earth's gravity and h the object's distance from the surface of the earth.
