Chapter 5: Newton's Laws of Motion
Newton's First Law Under ideal frictionless conditions, a body in motion would continue to move forever. NEWTON'S FIRST LAW: In the absence of a net external force,
Given the resistor below, determine (a) the equivalent resistance, (b) the
total current from the power supply, (c) the current through each resistor,
(d) the voltage drop across each resistor, and (e
Figure 1: Block of mass m on incline of angle
A box of mass m is on an inclined plane with angle . What is the
minimum coecient of static friction, s , such that the box will remain
stationary on the
Chapter 7: Work and Energy
Work Force times distance Work done is the force exerted over a distance W = F * dx W = F * s * cos theta W = F * s (dot product)

Chapter 11: Collisions
Impulsive Forces The force that two colliding bodies exert on one another acts for only a short time, giving a brief but strong push. Such a force that acts for only a short tim
Chapter 10: Systems of Particles
Momentum Newton's laws can be expressed very neatly in terms of momentum, a vector quantity of great important in physics. The momentum of a single particle is defined
Chapter 8: Conservation of Energy
Potential Energy of a Conservative Force The potential energy of the spring represents the capacity of the spring to do work by virtue of its deformation When we comp
