You will also use the concept of resonance to make pendulums swing without any initial push. Students spent the entire period performing the virtual activity on physical and chemical changes. The variables of the equation are: F which represents force, k which is called the spring constant and measures how stiff and strong the spring is, and x is the distance the spring is stretched or compressed away from its equilibrium or rest position. kinetic energy by swinging a pendulum and observing bar and wave graphs as they illustrate its energy. A simple pendulum consists of a mass m hanging at the end of a string of. For example, work done against friction should be negative, potential energy at the bottom of a hill should be less than that at the top, and so on. Science topics are based on the curriculum for Kindergarten through grade five, although many pages will be of interest to older students.

Use these boards as they are, customise them, or create your own boards to meet your own needs. Repeat the experiment three times, and calculate the average of the times you measured. Any force or combination of forces can cause a centripetal or radial acceleration. Dependence of Period on Length If all the mass of the pendulum were concentrated at a point, then the length L that appears in formula (1) would be the distance of that point from the pivot. for this lab we are trying to verify that gravity on earth is 9.
