Collision apparatus, small
Collision apparatus, smallApparatus for demonstrating Newton’s 3rd law of motion, which states that action and reaction are equal and opposite. Furthermore, the device is suitable for demonstrating momentum conservation.

Concave/convex acrylic mirrors, small
Concave/convex acrylic mirrors, smallMirror-coated plastic sheet. Mirror coated on both sides and shaped like a hole mirror.
Conductor sphere
Conductor sphereUsed as a target for the sparks from the Van de Graaff generator. The sphere’s mounting post has a socket that connects to the generator’s earthing socket.
Conical pendulum
Conical pendulumThe uniform circular motion of the conical pendulum allows the following to be investigated: centripetal force vs radius of orbit, centripetal force vs orbital period and determination of g. The disc moves almost without friction on its ball bearing, while the bob’s angle with the vertical is read on the graduated, balanced disc. The pendulum’s length can be varied using four interchangeable wires with hooks.
