In the first experiment we moved the Weights from the Weight, to the Car (Turning it into Mass). This is graph One, which is the upper of the two. And the results are to the left of it. The second experiment was where we only added to the Mass of the car. Activities: Plot the gradient, as the Acceleration and Mass have been listed, put these values into F=MA and see if the Gradient is equal to F. If so why so? If not, why not?

  • Velocity vs time graph

    Doodle Science teaches you physics in a less boring way in almost no time! This one starts with speed, the gradient of a distance vs time graphs, then moves on to acceleration, the gradient of a velocity vs time graph and the area under this graph (distance travelled). (1.56)

  • Virtual image

    Simple diagram showing a virtual image seen in a mirror. It is not possible to project a virtual image.

  • Virtual Oscilloscope

    uses shockwave

  • Wave animation

    A very clever Excel spreadsheet showing animations of a progressive wave moving from left to right and right to left and the formation of a standing wave.

  • Wave diagram

    Basic diagram of a wave. Amplitude = maximum displacement from the mid point, Wavelength = length/distance of a single wave, Frequency = number of waves passing a point per second. Speed of sound in air 330m/s. Speed of light in a vacuum 300,000,000 m/s

  • Wavelength Lab

    An animation that allows you to change and measure the frequency, velocity and wavelength of waves and hence take some interesting measurements

  • Weight and Mass

    One of a series of slightly zany physics tutorials - stick with it, they're good. This one compares weight with mass.

  • Weightless

    "Movement in Microgravity: Skylab to Space Shuttle" 1988 NASA Weightlessness Footage

  • Westminster kit - components

    The components used by the Westminster Motor kit to make a simple D.C. motor.

  • Westminster kit - D.C. motor

    Complete DC motor from the Westminster kit

  • White dwarf

    A dying star, no longer undergoing fusion, with a mass similar to our Sun and a size similar to Earth. A White Dwarf will cool to a Black Dwarf.

  • Why telescopes in space ?

    Water vapour in the atmosphere absorbs infra red.
    Visible light makes it through the atmosphere but images are blurred
    The Earth's atmosphere blocks X-rays and gamma rays..

  • Wind Turbine
  • Work Done, Energy and Power
  • Worked Example - Free Fall

    Worked example (7.18) using the equations of motion to find the height of a building or the time taken to fall.

  • Writing nuclear equations

    A short tutorial (6.37) on writing nuclear equations for alpha, beta (+ & -) and gamma decay

  • X-Ray body scan

    Actually a fake picture of what a full body scan might look like.

  • X-Ray of lorry

    An x-ray of a statue of Sheba (similar to the one at CERN) taken at the Rotterdam customs. The 9.3MeV source is strong enough to distinguish between a 1mm copper wire and 30cm of steel.

  • X-ray tractor
