The discipline of tribology is being leveraged to reduce the level of unnecessary energy used by mechanisms, and, therefore, is fundamental to decreasing the levels of emissions of various industries.

Segment 4H: Conservation of Energy We explore the inner workings of a hydroelectric dam. Segment 4H: Conservation of Energy We explore the inner workings of a hydroelectric dam as we learn about the ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are getting a handle on how to attenuate or stop it completely ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...
