![]() | Vernier Optics Expansion Kit Add the Vernier Optics Expansion Kit to your Vernier Dynamics System to conduct optics experiments, such as image formation with lenses and light intensity vs. distance. You can even use the kit to build a basic telescope. The Optics Expansion Kit includes:
The parts of the Optics Expansion Kit snap on to the track, so that the parts can be left in place while the track is moved. The three lenses are permanently mounted in three plastic supports. The light source is LED-based, so that it uses less energy and is cool to the touch. A rotating disc on the light source gives you the option of a radiant object, a point source, an "L" with 2 by 1 cm dimension, and parallel lines for resolution experiments. The power supply is the same as the LabQuest power supply. An additional aperture plate is included for experiments based on lens diameter and shape.

The Vernier Dynamics System comes with a track, and standard and plunger carts, but you can purchase additional tracks and carts for your needs. If you own more than one track, combine multiple tracks easily using our Track-to-Track Coupler to expand the track length needed in your experiment.
Ordering Information| Track-to-Track Coupler The Track-to-Track Coupler rigidly connects two tracks for larger experiments and demonstrations. | T2T-VDS | $30 | ||
| Combination Track/Optics Bench The Combination Dynamics Track and Optical Bench is black anodized aluminum and includes a metric scale. Extremely rigid, this 1.2 meter track will not sag under use. The track includes 2 Adjustable Two Foot Levelers. | TRACK | $114 | ||
| Standard Cart These low friction carts are designed to study motion and collisions on the Vernier Dynamics Track. Vernier carts are also compatible with other common carts and tracks. | CART-S | $85 | ||
| Plunger Cart These low friction carts are designed to study motion and collisions on the Vernier Dynamics Track. The Plunger Cart has a spring-loaded plunger for elastic collisions. Vernier carts are also compatible with other common carts and tracks. | CART-P | $98 | ||
| Adapter for Pasco Cart The Adapter for Pasco cart allows the attachment of a Vernier Dual-Range Force Sensor to a Pasco cart. | PCA-DFS | $4 | ||
![]() | Ultra Pulley Attachment Add an Ultra Pulley to your Photogate to monitor motion as a string passes over the pulley, or as the pulley rolls along a table. You can also connect the Ultra pulley to our track with the Pulley Bracket. | SPA | $24 | |
| Pulley Bracket The Pulley Bracket attaches an Ultra Pulley to the end of a Vernier Dynamics Track. | B-SPA | $12 | ||
| Cart Picket Fence The Cart Picket Fence is a small plastic strip for doing photogate motion timing with dynamics carts. When the Cart Picket Fence passes through a photogate, the cart's velocity and acceleration as a function of time can be accurately measured. | PF-CART | $6 | ||
![]() | Cart Fan Several Physics Education Research–informed curricula make use of fans to study motion under a constant force. Our two-speed Cart Fan attaches to our dynamics track carts, and you can monitor the cart position with a Motion Detector. You can get a beautiful parabolic position vs. time graph. The Cart Fan accessory attaches to a Vernier Cart using magnets, so they are easy to attach and remove. | FAN-VDS | $60 | |
![]() | Friction Pad After working hard to make our dynamics carts very low friction, we've now added some friction back, so that you and your students can study friction in a controlled way. Add a Cart Friction Pad to your Vernier Dynamics System, and watch the carts move under very consistent friction force. Setting the friction amount is as simple as turning a knob. | PAD-VDS | $30 | |
![]() | Color Mixer Kit Experiments in additive and subtractive color mixing can be easily and conveniently carried out using the Vernier Color Mixer Kit. The Color Mixer Kit consists of a three-color LED illuminator with power supply, a lens, and a double-sided screen. The intensity of the red, blue and green LEDs can be smoothly controlled from the light source. Requires one Vernier Track to serve as an optics bench. Related Products | CM-OEK | $150 |

Ordering Information| Adjustable Two Foot Leveler Use this leveler to adjust the height of the Vernier Dynamics Track. | AL-VDS | $10 | ||
| Adjustable End Stop Attaches to the end of the Vernier Dynamics Track to prevent the cart from leaving the track. | AS-VDS | $8 | ||
| Velcro/Magnetic End Caps This kit includes replacements for the velcro tabs, magnet inserts, end caps, and screws that are included with new carts. | VMC-VDS | $5 | ||
| Mass for Dynamics Cart This 500 g steel block is a great accessory for Newton's second law labs. It attaches to a Vernier or Pasco dynamics cart and leaves room for both a Dual-Range Force Sensor and an Accelerometer. | MASS | $12 | ||
| Motion Detector Bracket This bracket allows a Vernier Motion Detector to be attached to the end of a Vernier Dynamics System track for studying cart motion and collisions. | MDB-VDS | $11 | ||
| Photogate Bracket This bracket attaches a Vernier or Pasco photogate to the Vernier Dynamics Track. | PGB-VDS | $5 | ||
![]() | Rod Clamp The Rod Clamp is used to attach one end of a Vernier Dynamics Track to a vertical ring stand rod. This configuration is most often used to create a ramp. | RC-VDS | $7 | |
| Fasteners for Dual-Range Force Sensor and Accelerometer The Vernier Dynamics System Accessory Kit consists of two small and one large t-nut fasteners. The t-nuts are used to attach accessories such as a Dual Range Force Sensor or the Low-g Accelerometer to the Vernier Dynamics Carts. The t-nuts can be attached at any point along the three slots in the top of the carts. | ACC-VDS | $11 |
