PHFM0451 - Simple Hall's Carriage
Both the body and wheels are made from high impact plastic. The recession in the car allows for additional weight. The hole in the front of the molded plastic body allows you to attach a cord, which is useful with an incline plane.
(5- ¼" x 2" x 1- ½"; .1Ib).
PHFM0453 - Hall's Carriage
This unit is designed to be used with all types of inclined planes. Overall length is 14cm.
PHFM0455 - Friction on an Incline Plane
This is a simple device for studying friction and the varying degrees of friction in relation to an incline. The unit is made of smooth wood with a metal pulley attached to the incline and a large protractor for accurately recording the angle of incline. Three different sized boards with eye hooks are also included for study of how displacement, surface contact and weight affect frictional forces.
PHFM0457 - Friction on an Incline Plane
Same as above except for the changes of the friction piece and weights. A carriage car replaces wooden plank and hooked weight (slot weights) replaces tray to hold weights.
PHFM0459 - Incline Plane, Metal
For determining vertical and horizontal force components, friction losses, etc. Consists of a heavy base and 3" x 22" incline, supported by a cast aluminum protractor graduated to 45 degree. The adjustable pulley, with hardened steel bearings, responds to a minimum of 20g. Cart weight pan not included.
PHFM0461 - Friction Apparatus
This set includes a friction block and a friction board, both made of high quality, smoothly finished pine wood. The friction block has a hook for a spring scale and three 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 3 – 50g weights and a 100g spring scale. Board is 20" x 2" and the block is 4" x 1.5" x 1".
PHFM0463- "V" Type Track
This unit is a simple way to science students to perform the principle of friction on "V" type track.
PHFM0465 - Two Double Cone and Incline
This unit is used to defy the law of gravity. When the track is widened, the center of mass of the cone is lowered. So it appears to violate the law of gravity by uphill.
PHFM0467 - Single Double Cone and Incline
This unit is used to defy the law of gravity. When the track is widened, the center of mass of the cone is lowered. So it appears to violate the law of gravity by uphill.
PHFM0469- Friction on Inclined Plane
This is a simple device for studying friction and the varying degrees of friction in relation to an incline.
PHFM0471 - Friction on Inclined Plane
This is a simple device for studying friction and the varying degrees of friction in relation to an incline.
