Q: How does a lever work? - National Science Teachers Association
... Let’s apply this to a lever, shown in Figure 3, page 60. This lever is a ruler, using a pencil as a fulcrum. Feel free to get your own ruler and pencil to play along and experience the operation of a lever. This lever is being used to lift a rock. ...

... The simplest body arising in the study of motion is a particle, or point mass, defined by Nikravesh [65] as a mass concentrated at a point. According to Newton's second law, a particle will accelerate when it is subjected to unbalanced forces. More specifically, Newton's second law as applied to a p ...

Types of Friction - AustinMeehanAcademy3
... Weight is related to mass, but they are not the same. ◦Weight changes when gravitational force changes. Mass: the amount of matter in an object. ◦The amount of mass in an object does not change. This can get confusing… because weight and mass are “constant” on Earth, the terms weight and mass are of ...
