This is a variation on the extending a spring experiment. Here the measurements are of compression and the support sheet...
In this activity pupils measure how the load the punt supports first hand experience of an buoyancy force and to encourage...
Civil engineers, dressmakers, dentists and fishermen are just some of the people for whom a knowledge of the strength and...
Back to boat: the larger the hole it made in the water, the greater the support force–the buoyancy force.
When two surfaces are in contact there is a force acting on each surface that acts in a direction to stop them moving past one...
When objects move through a fluid (a liquid or a gas) their progress is opposed by a force which acts on the object and in the...
There are three kinds of contact forces that can support an object.
Distinguishing–eliciting–connecting. How to:
A floor seems to just be. How such a passive object can provide an upward force is indeed a puzzle.
This misconception appears in two forms. The first holds that friction happens only when things move (slipping). This idea is...
For many learners air is seen as nothing. Comparing the mass of air in a small domestic room to the mass of a child might help...
There's a good chance you could improve your teaching if you were to try these strategies.
