Chapter 5 The Laws of Motion
Forces are what cause any change in the velocity of an object.
Newtons definition: A force is that which causes an acceleration
Classes of Forces
Contact forces involve physical contact between two objects
Field forces act thr

Uniform Circular Motion, Acceleration
A particle moves with a constant speed in a circular path of radius r with an acceleration.
The centripetal acceleration is always perpendicular to the

Position and Displacement
The position of an object is described by its position vector
The displacement of the object is defined as the change in its position.
In two-or three-dimensional kinematics, everything is the s
THE STANDARD MODEL OF ELEMENTARY PARTICLES
The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing
the chemical elements, it lists the fundamental particles that make up the atoms that make up the
