Dynamic Trolley, Wooden (Pair)

A Wooden Dynamic Trolley (Pair) is a fundamental mechanics tool used in physics labs to demonstrate and investigate the laws of motion. These identical trolleys are typically 300mm long and designed to move with minimal friction to ensure high-quality experimental data.

Primary Function and Experiments

Trolleys are primarily used to provide a hands-on understanding of classical mechanics:

• Newton’s Laws of Motion: Used to demonstrate that force equals mass times acceleration (F = ma) and the principle of action and reaction.
• Conservation of Momentum: By colliding two trolleys (either elastically or inelastically), students can verify that total momentum remains constant in a closed system.
• Energy Transfer: Useful for exploring the conversion between potential energy (stored in the spring) and kinetic energy (motion).
• Velocity and Acceleration: Often paired with a ticker timer or light gates to measure changes in motion over time or down an inclined runway.

Design 

• Low-Friction Wheels: Usually mounted on three smooth-running wheels (often with ball bearings) to minimize energy loss to friction.
• Spring-Loaded Impulse Rod: A built-in plunger that can be set to different compression levels to provide a consistent, repeatable pushing force.
• Stackable Design: Includes pins or holes that allow trolleys to be stacked, effectively doubling or tripling the mass for comparative experiments.
• Collision Attachments: Many models feature Velcro pads for studying inelastic collisions (where objects stick together) and rubber corks or springs for elastic ones.
