Direction of force, conductivity, force reduction, and simple electric circuits. 110V/60Hz adapted for U.S. labs.
The students observe the force that needs to be applied when lifting a mass with the aid of a fixed pulley and notice that the force that needs to be applied when using a fixed pulley is the same as...
Conductive and non-conductive materials with Cobra SMARTsense, supplied in the U.S. by American Scientific. Contact us for specifications.
The students observe the effects of the principle of action and reaction and they find out that two connected dynamometers always indicate the same force, leading to the conclusion that when one body...
The students observe the force that needs to be applied when lifting a mass with the aid of a fixed pulley and a moveable pulley and notice that the advantages of the previous experiments with only...
The students observe the relationship between weight and the length of the lever arm of a one-sided lever and notice that the point of application of different masses affects the effort which is...
The students will observe the relationship between weight and the length of the lever arm of a two-sided lever.
The students observe the force that needs to be applied when lifting a mass with the aid of a moveable pulley and notice that the force that needs to be applied when using a moveable pulley is less...
The students observe the behaviour of a dynamometer that is subject to various forces when different masses are suspended from it and notice that the weight of the suspended masses increases when the...
The students will investigate the current in a simple electric circuit. They will observe the brightness and current consumption of various light bulbs and conclude that the total current depends on...
The students observe the force that needs to be applied when transporting a mass and notice that the process can be performed with less force if the mass is not simply lifted straight up but rather...
The students will observe an electric circuit with two light bulbs connected in series as well as in parallel.
The students examine the behaviour of a thin, conductive wire in an electric circuit, observe that the wire heats up due to the current flow and draw the conclusion that electric current can be used...
