Ordinary Differential Equations
... where ω 0 k/m is the angular frequency of the un-damped oscillator (b=0). The forced oscillator vibrates at the frequency of the driving force and that the amplitude of the oscillator is constant for a given driving force because it is being driven in steady-state by an external force. For small d ...

... Whenever an object moves against another object, it is likely to experience frictional forces. These are forces that act in the direction opposite to the direction of movement. Friction can be useful. Friction between our shoes and the floor stop us from slipping, and friction between tyres and the ...

The equations above show that the center of mass of a system of particles moves as though all the system's mass were concentrated there, and that the vector sum of all the external forces were applied there. A dramatic example is given in the figure. In a fireworks display a rocket is launched and m ...

Analyzing a Dual Fan Carts Motion (Low Tech).
... In order to accurately measure the force produced by the fans each lab group will need an electronic lab scale or lab balance, such as a triple beam balance. Typically, each fan with fresh alkaline batteries will have a difference in mass of about 10g = 0.01kg, which is a difference in weight of 0.1 ...
