A. Wooden Dynamics Trolley Ideal for experiments in:
• Basic acceleration down an inclined plane (diluted gravity)
• Investigation of the effect of different accelerating forces on different masses
• Investigation of elastic collisions between trolleys • Investigation of inelastic collisions
• Investigating the sharing of momentum between two trolleys
• Simple harmonic motion
The trolley consists of a rectangular body carried upon three low-friction wheels and is supplied with one strong spring plunger and three dowel pegs.
Several trolleys may be stacked on top of each other and are held in position by holes drilled underneath which fit over dowel rods placed in corresponding holes in the upper surface of the lower trolley. This enables the effective mass of a trolley to be increased to twice or three times its basic mass. Sufficient space is provided on the flat top of the trolley for the addition of heavy loads. In the front end of the trolley are two holes with corks and if long pins are pushed through these corks, two trolleys can be made to stick together for inelastic collisions.
Dimensions: 290 x 140 x 90mm. Mass: 0.87kg. Direct Delivery – up to 7 days E8A42006
B. Trolley Runway (Long)
Designed to provide a smooth, flat, easily inclinable surface for dynamics experiments using trolleys. With metal side rails and plastic feet. Dimensions: 2.4 x 0.3m
This is similar to the standard runway but at only 1.5m long is more convenient where storage space is limited. Dimensions: 1.5 x 0.3m.

each £113.95 C. Replacement Wheels, Red
For use with trolleys originally equipped with red wheels only. Direct Delivery – up to 7 days E8R07429
D. Elastic Cord with Eyelets
Comprising a length of elastic cord with a brass eyelet at each end. Dimensions: 150mm unstretched length between eyelets.

pack 10 £19.95 E. Dynamics Trolley Metal each £87.95
Dynamic trolley, all metal, compact design, one end of metal body carries an integral spring plunger/ trigger system for explosion experiments whilst the other end has a clamping screw for attaching ticker tape. Other built-in facilities includes hook & loop pads for non elastic collisions and locating pins to permit secure stacking of two or more trolleys. Compact design, constructed with all metal. Each trolley measures: L160 x 80 x 50mm.
