FALLING BODIES APPARATUS

FALLING BODIES APPARATUS:

A projectile is any object thrown into space by the exertion of a force. Although any object in motion through space may be called a projectile, the term more commonly refers to a ranged weapon. Mathematical equations of motion are used to analyze projectile trajectory.

Specifications:

• For demonstrating the independence of horizontal and vertical velocities of bodies falling freely under the effect of gravity.
• The apparatus consists of a wooden block on top of which is pivoted a spring loaded L-section metal launching bar having a trigger catch.
• A small recess near either end of the metal bar serves to locate 19 mm steel balls.
• Releasing the catch makes one ball drop simply vertically, while the other one is projected horizontally.
• Both the balls simultaneously hitting the floor substantiate the fact that the vertical velocities of both the balls are same at any instant.
• Supplied complete with a pair of steel balls, which may be stored in a covered recess in the wooden body.
