... Friction is a force that opposes motion between two objects in contact. Friction can be a nuisance (e.g. it slows things down when you don’t want it to when driving a car or riding a bike). Friction can also be useful (e.g. brakes on a bike, and to enable us to walk). Experiment: To demonstrate fric ...

... Isaac Newton, put forth three laws. The first of these laws, sometimes referred to as the law of inertia is that “an object at rest tends to stay at rest, unless acted upon by an unbalanced force”. This essentially means that an object that is still doesn’t want to move, so something else will have ...

It can’t make the energy disappear altogether because energy, as we’ve seen, is a conserved quantity: it can’t be created or destroyed. But energy can be transferred between objects or converted from one ...
