Relativity is the study of how different observers measure the same event.
Special relativity deals with observers who are in uniform motion. General relativity
includes accelerated relative motion and gravity. Albert Einstein

Psychology and Mathematics. M
Week 3 Lesson 6
Electric Charge and Electric Field
Static Electricity and Charge. Conservation of Charge
Existence of Static Electricity has been known since ancient times. The first record of its
effects dates to ancient Greeks who noted more than 500 ye
Week 2 Lesson 4
Density is the mass per unit volume of a substance or object
m is the mass; V is the volume occupied.
SI unit of is kg / m3 .
Representative values are given in Table 9.1, p. 314.
Pressure P is defined to
Week 4 Lesson 8
Optic is the branch of physics that deals with behavior of visible light and other
electromagnetic waves. When light interacts with object several times as large as its
wavelength, it travels in straight lines and acts lik
Week 2 Lesson 3
Work, Energy, and Power
We can define energy as the ability to do work admitting that in some circumstances not
all energy is available to do work.
Work: The scientific definition. For work to be done a force must be exerted and there
Week 3 Lesson 7
All magnets may attract or repel other magnets. All magnets have two poles north
(points toward the north) and south (points toward the south) magnetic poles. Like poles
repel, and unlike poles attract.
Only certain materials, su

Week 2 Lesson 5
Oscillatory Motion and Waves
What do an ocean buoy, a child in a swing, a guitar string, and atoms in a crystal have in
common? They all oscillate that is move back and forth between two points. Some
oscillations create waves. A vibrating
Week 1 Lesson 2
Two Dimensional Kinematics:
Suppose you want to walk from one point to another in a city (Figure 2.1). The straightline path that a helicopter might fly is blocked to you as a pedestrian, so you are forced to
