Chapter 5 – Force and Motion I

Chapter 5 – Force and Motion I I. Newton’s first law: If no net force acts on a body, then the body’s velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially.

Chapter 6 – Force and Motion II

A centripetal force accelerates a body by changing the direction of the body’s velocity without changing its speed. v, a = ctes, but direction changes during motion.-Centripetal force: a, F are directed toward the center of curvature of the particle’s path. 3 III. Non-Uniform circular motion

Chapter 29 – Electromagnetic Induction

Faraday’s Law of Induction: - The induced emf in a closed loop equals the negative of the time rate of change of the magnetic flux through the loop. dt ε= − dΦB - Increasing flux ε< 0 ; Decreasing flux ε> 0 - Direction: curl fingers of right hand around A, if ε> 0 is in same direction of fingers (counter-clockwise), if ε< 0

Combination of Waves

Interference of Waves When light waves travel different paths, and are then recombined, they interfere. Each wave has an electric field whose amplitude goes like: E(s,t) = E 0 sin(ks-ωt) î Here s measures the distance traveled along each wave’s path. Mirror 1 2 * + = Constructive interference results when light paths differ

Pounds Mass and Pounds Force - Durham College

Force is an action exerted upon an object that causes it to accelerate. In the S.I., force is measured using Newtons. A Newton is defined as the force required to accelerate a 1 kg object at a rate of 1 m/s. 2. 1 N ≡1 kg ∙m/s. 2. Definition of the Pound-force . The pound-force (lbf) is defined a bit differently than the Newton. One pound ...

BALANCING OF ROTATING MASSES

The force caused by unbalance increases by the square of the speed. 4. If the speed is doubled, the force quadruples; if the speed is tripled the force increases www.getmyuni.com. by a factor of nine! Identifying and correcting the mass distribution and thus minimizing the force and resultant vibration is very very important ...

Oleoresin Capsicum: Pepper Spray as a Force Alternative

Pepper Spray as a Force Alternative Introduction Oleoresin capsicum (OC). or "pepper spray." is gaining acceptance and popu- larity among law enforcement officers and police agencies as a safe and effective method of incapacitating violent or threat- ening subjects. There is. however, a lack of objective data on OC. its risks. and its benefits.
