To demonstrate that gravitational acceleration down an incline is independent of the falling mass. The two wheeled trolley runs across the room on an inclined overhead cable. Mounting hardware, 10.8 m of cable, and full operating instructions are supplied with the unit. Size is 15 x 10 cm. Mass set and hanger are not supplied with apparatus.
Demonstrate that the forward motion of a ball ejected vertically is the same as that of the vehicle from which it was ejected. A car with ball bearing wheels and vertically mounted spring loaded barrel. The barrel permits two spring tensions. Complete with a 25 mm steel ball and release pin.
This battery-powered timer produces 30 to 50 marks per second for dynamic experiments. 1.5V motor operates on two D-cell batteries (not included). A wooden base improves stability, reduces vibration, and permits attachment to a ring stand post. The striker mechanism acts against an aluminum plate to produce an improved-dot definition on the ticker tape.
Everything is needed to measure the relationship between centripetal force and mass. This kit includes a hollow tube handle, rubber stopper (rotating weight), washers (stationary weights), nylon thread, and complete instructions for you to do centripetal force demonstrations.
A 4cm plastic pulley is mounted on a table clamp with low friction brass cone bearings. It can be used on lab tables, inclined planes, or force tables for experiments involving the resolution of forces, friction, or motion. It can clamp onto surfaces up to 3cm thick. A crossbar on the screw offers a better grip for tightening and the…
Curved ramp to deliver a ball for collision with constant energy. The apparatus includes: Two ½ inch steel balls, One 16mm glass ball, One 1 inch wooden plumb bob. With Instructions.
Students will never get bored with these brightly colored pulleys. They will add color & excitement to any mechanics experiment. These standard-size pulleys are less intimidating to smaller children. Ages 10+
The constant motion machine moves with a uniform speed in a straight line. The machine has a hook attached to its rear end and can pull dynamics carts to demonstrate the concept of vectors and velocity. Requires two AA batteries, not supplied with apparatus.
For experiments in velocity, acceleration, momentum, elastic collisions etc. The plastic carts has deep wells for additional masses, includes two rubber bumpers for inelastic collisions, two spring loops for elastic collisions and an instructions. Each measures 13 x 5 x 3.5 cm and has a mass of 70 gm.
Demonstrates conversion of kinetic energy into heat and sound energy during a collision. Consists of a pair of heavy steel balls. When the balls strike against each other with a piece of paper between the balls, the heat causes a hole to appear in the paper. The kinetic energy of the balls upon collision is converted to heat which is…
For verifying laws of composition and resolution of forces, comprising a machined aluminum table 40 cm dia., scale graduated 360°, on heavy vertical support rod and tripod base. Complete with one ring, and 4 sliding clamp pulleys. Supplied with four cords with rings at one end, without masses.
Dynamic carts with low friction ball bearing wheels and space to carry five ordinary brick. Each cart is supplied with one heavy and one light bumper spring, which can be easily changed. Complete with a loop spring and instructions. Each cart measures 7.5 x 25 cm, exclusive of wheels and bumper spring.
This set includes a fiction block and a friction board, both made of smoothly finished pine wood. The friction block has a hook for the spring scale and two compartments for additional weights. It can be placed face-up or sideways. Students can vary the weight or area of contact to see their impact on the friction force. Comes with three…
Use this friction block with an attached hook for force and motion studies. This wood block measures approximately 6" x 3" x 1.25" and weights about 5.75 ounces.
To understand the relation between friction and smoothness of materials consists of three wooden blocks measuring approximately 3-15/16″ L x 2- 3/4″ W with hooks. The first block has a polished side, the second has a sandpaper side, and the third has an aluminum side. Complete with the polished wooden base measuring 14″ L x 2-3/4″ W.
To illustrate the concept that friction depends on the nature and smoothness of materials. The kit consists of a glass mirror with sandpaper affixed to one side and two wooden blocks, one with a hook and the other with an eye. The latter block has a mirror cemented to one face. Both static and sliding frictional forces between different surfaces…
To Study the effects of friction using 4 different surface materials on a board Includes surface board, hooks and wooden blocks, With instruction manual.
Gyroscope with Gimbal Cradle is an excellent, inexpensive apparatus, which is used to explore the mysteries of precession, inertial guidance, gyroscopic compasses, and stabilization. It is precision machined and balanced and runs smoothly with little vibration. Provided with pull string with handle, weight set, and support hook. A pendulum mounting is also supplied that can be used for investigating the…
Molded body with a central well for additional masses. A hole in one end of the body enables a cord to be attached. Dimensions: approx. 13 x 5 x 3.5 cm.
This durable carriage has a one-piece high-impact plastic body. The machined aluminum wheels and axles are mounted on hardened steel cone bearings for minimum friction and long life. Designed to be used with all types of inclined planes. 5 3/4” L. Ages 13+
With a built-in length and angle scales. Metal construction, the plane is 60cm long and adjusts from 0° to 45°. With an adjustable pulley, roller, cord, and weight pan.
