Students learn a little about friction, pressure and the release of energy that can be related to earthquakes. Introduction Just by looking at the Earth, it would appear that the surface was smooth ...
... of the rolling can will be stored as potential energy in the tightly twisted rubber band (some will be transferred to friction (heat) and sound). Once the band has reached its limit, the stored energy ...
... water has inertia — it will not move unless a big enough force acts on it. The force pulling on the glass of water is the friction between the tablecloth and the glass. Since the tablecloth and glass ...
Challenge your students to put a penny in a cup without touching it. Introduction The solution is to use inertia to your advantage by taking the playing card out of the way as quickly as possible. ...

... is moving, it'll keep moving unless a force stops it. The friction between the table and egg will slow the egg and eventually stop the spinning. Though the liquid inside the egg keeps moving, it too slows ...
... the friction between the string and your fingers produces the vibration, which is amplified (made bigger) by the plastic container. There are three ways to change the pitch of a vibrating string. Pitch ...
... the force of friction pushes back. The more weight on your finger, the greater the force of friction. One of your fingers is supporting slightly more of the ruler's weight than the other; that finger gets ...
... (kinetic energy) and heat. The can will roll if the energy stored in the wound rubber band produces a force great enough to overcome the force of friction between the bead and the disk and between the ...
