1.2 m PAScar Dynamics System - ME-6955A



The PAScar 1.2 m Dynamics System is the most economical way to equip your lab with carts and tracks for Newton's Laws, collisions, velocity and acceleration experiments. With accessories, you can expand your system to do additional experiments such as constant force with a fan cart, friction, and oscillations. Also, all PASCO Dynamics Systems are specifically designed to accommodate sensors for computer data acquisition.

Typical Experiments

  • Experiment 1 -- Collisions
  • Experiment 2 -- Conservation of Energy
  • Experiment 3 - Kinematics
  • Experiment 4 - Coefficient of Friction
  • Experiment 5 - Predicting Acceleration
  • Experiment 6 - Cart Calibration (Spring Constant)
  • Experiment 7 - Sliding Friction and Conservation of Energy
  • Experiment 8 - Conservation of Momentum in Explosions
  • Experiment 9 - Newton's Second Law
  • Experiment 10 - Newton's Second Law II
  • Experiment 11 - Acceleration Down an Incline
  • Experiment 12 - Conservation of Energy


The 1.2 m PAScar Dynamics System has unmatched versatility combined with high quality components:

  • PASCO's aluminum tracks combine durability with utility. The aluminum extrusion is rigid and light, yet straight. Each track includes a measuring tape for easily measuring displacements along its length. Grooves along the side of the track allow key accessories such as photogates, rod clamps and angle indicators to be attached.
  • PAScars have low-friction, ball bearing, knife-edge wheels which mean student data more closely matches theory. With spring-loaded suspension wheels that retract into the body, they are protected from drops or "skateboarding."
  • Additional PAScar Features:
    •Three-position Plunger -- Provides reproducible impulses and explosions
    •Three Mounting Holes -- For accessories
    •Polycarbonate Body -- Total mass: 250 g
    •Mass -- One 250 g mass included for each car.
    •Mass Tray -- Add mass to easily double or triple car mass
    •Magnets -- Installed on one end for elastic collisions
    •Velcro Tabs -- For inelastic collisions

How It Works

Few investments in physics lab equipment provide more learning opportunities than the PAScar Dynamics Systems -- perfect for experiments in Newton's Laws, collisions, velocity and acceleration. Get the advantages of a very low-friction apparatus without the noise and expense of air tracks.

  • The PAScar's body and plunger are made of high-impact polycarbonate plastic -- extremely durable carts designed to survive tough classroom environments.  These carts are a lower cost alternative to our Classic Carts.
  • The sturdy aluminum track is available in either 1.2 m or 2.2 m lengths depending on your lab size and the experiments you wish to perform. This Dynamics set features the 1.2 m length track.
  • The newly redesigned feet and endstops have captured nuts which automatically align with the track T-slot, making it easy to slide them onto the track.
