About This Product
Pulling the same block across each surface with a spring balance shows the force needed to start it moving and to keep it moving, so learners can work out and compare friction coefficients. Adding mass to the block shows that friction rises with the normal force, and timing slides down an inclined ramp shows how friction reduces acceleration.
Frequently Asked Questions
What surfaces does the Force and Friction Model have?
It has three ramps faced with sandpaper, glass and iron, giving a rough, a smooth and a metallic surface for comparison.
Does the model measure force by itself?
No. The force is read with an external measuring device such as a spring balance.
