Sensible Science Simulations

Capacitor- charging and discharging a capacitor through a resistor:Show, in 3D, how a capacitor works... This simulation shows a capacitor in three states: Charging "Off"DischargingA switch is used to select a state. The simulation shows electrons moving appropriately, the charge on each plate, cell orientation, the correct orientation of polar molecules in a dielectric and correct values. The graphs, when expanded, show the recurring time constant.  Choose to show:Graphs (I/t, Q/t, V/t with tim

Motion Graph MatchImprove understanding of kinematics...Challenge your students to match three graphs (x/t, v/t, a/t) and one moving ball, each of which describes the same motion.The app keeps the score. Iterations are never the same, and some are more difficult than others. Choose to show: Graphs where the velocities are all constant (v = ∆x/∆t)Graphs where the accelerations are all constant (a = ∆v/∆t)Graphs where the jerks are all constant (jerk = ∆a/∆t)This application, once downloaded, is s

Buoyancy: Change every variable (except viscosity) Show how the buoyant force is related to the densities of the object and the fluid, volume of the object, volume of the displaced fluid, acceleration due to gravity. Vectors show the buoyant force, the force of gravity, the normal force, and, if you wish, a push or a pull. Place the object in any position, or push or pull the object vertically, and view from any angle by rotating, panning or zooming the animation). Choose to display the calcula

Inverse Square Law Simulation:Challenge your students to find a relationship between intensity of light and the distance from a point light source using this highly configurable 3D simulation. Adjust:The distance from the light source for one or two areasThe power output of the light sourceThe spread of the lightChoose to showOne or two areasArea calculationsIntensity calculationsSpheres (for discussion)The simulation, once downloaded, is self-contained... it doesn't need an internet connection.

description

The principal purpose of this simulation is to show that:... as the linear acceleration of the ladder and man is zero, then the net force on it is zero.... as the angular acceleration of the ladder and man is zero, then the not torque is zero, no matter where one places the common point about which torques are calculated. One can change:ladder lengthladder angleladder massPosition of man standing on ladderMass of man standing on ladderCoefficient of friction between ladder and floorPosition of c
