A useful activity when teaching physics. Students draw the graphs of your motion on mini white boards. Suitable examples included with expected answers.
Simple demonstration of balanced and unbalanced forces or resultant force

A simple physics demonstration using weights on two sides to create balanced and unbalanced forces on the trolley and to observe their effect. Useful when teaching physics.

A short vídeo discussing how to use a motion sensor when teaching distance time graphs. Video developed as part of an Ogden Trust Senior Teacher Fellowship. Thank you for their support in giving me more time to make videos and develop physics teaching ideas.
Slow dance of candles in a sound wave
Просмотров 127Месяц назад
A lovely demonstration showing candle flames oscillating as sound waves pass through. By almost matching the frequency of the sound waves to the frame rate of the video the flames appear to oscillate very slowly. Easy to set up in a physics lesson. Very nice to show live and with a video feed at the same time.

    Question from a pleb. When that water dribbles out of the horizontal straw, is it not creating a partial vacuum at the top of the bottle? Thus helping atmospheric pressure to keep the water in?

    • @SimonPoliakoff
      @SimonPoliakoff 2 дня назад

      I prefer to say reducing the pressure of the air in the top rather than creating a partial vacuum but yes you have understood the idea that there is less pressure from the air above the liquid. Good job.

  • @AmmoBops
    @AmmoBops 2 дня назад

    I guessed Lower, Bigger, Middle But now I realize that the lack of liquid in the lower has less gravitational force to keep it down, and conversely the bigger has too much to allow it to sit for longer. And the middle is a nice balance

  • @V2RocketScientist
    @V2RocketScientist 2 дня назад

    The lowest center of mass would be approximately having the same weight in liquid as weight of the bottle, minus whatever half the weight of the bottle is that's filled.

    • @SimonPoliakoff
      @SimonPoliakoff 2 дня назад

      This would make a nice investigation - change the volume or mass of liquid and see how the angle of topple changes.

    Excellent demonstration! I have a lab for school and my goal is to investigate the relationship between the horizontal distance of the two strings with its period. Do you know which equation connects the two variables because I’ve looked at many studies online and many people use different equations.

      If you have a known mass of the isotope then from the rate of radiation being emitted you can calculate the half life.
