Law of Motion Kit SW471

Law of Motion kit has been designed to study linear motion, momentum and kinetic energy of trolleys moving on a smooth track. Picket fence masks attached to the trolleys and light gates mounted on an overhead rail, enable calculation of velocity and acceleration of the trolleys using free software. Experiments in Laws of motion, including action and reaction, force and acceleration and study of momentum and kinetic energy in collisions can be investigated with the equipment. The track is of superior quality stainless steel which together with low friction trolleys, ensures smooth travel. Soft buffers at the track end to prevent damage to the trolleys and a pulley provides for a hanging weight attached to a trolley.

Law of Motion Kit


Exp-1 To find the velocity of an object.

Exp-2 To determine the average speed of an object.

Exp-3 To determine the acceleration of a moving object.

Exp-4 To demonstrate the elastic collision.
