... changes in motion. The amount of motion depends on the object's mass. Newton's 2nd Law of Motion can be expressed as force equals mass times acceleration. It explains that force causes acceleration and mass resists acceleration. The more mass, the more force you need to make the object move. Acceler ...

... Static friction occurs when the two objects are not moving relative to each other (like a desk on the ground). The coefficient of static friction is typically denoted as μs. The initial force to get an object moving is often dominated by static friction. (Force between objects at rest) Kinetic f ...

Lesson 1: Newton`s First Law of Motion
... Inertia is the resistance an object has to a change in its state of motion. Galileo, the premier scientist of the seventeenth century, developed the concept of inertia. Galileo reasoned that moving objects eventually stop because of a force called friction. Isaac Newton built on Galileo's thoughts a ...
