Minela Sljoka Notes on Physics Inertia- tendency of an object to maintain motion. Property of matter. Not newton’s first law. Matter wants to maintain motion- moving objects want to stay in motion if stopped wants to stay stopped. Mass is measure of inertia. Things have mass because they have inertia. Units: kg Symbol m in equation. Inertia is most constantly called rest mass but we call it mass because we are dealing with speeds not going to speed of light. Kinetic Energy- v^2 is proportional

.Physics is the field of scince that controls the Earth‚ the Moon‚ the Sun and the Universe It is the science of matter and its motion‚ space-time and energy. Physics describes many forms of energy - such as kinetic energy‚ electrical energy‚ and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will not be an exaggeration

to trigger the device. Two of its earliest applications were as part of smoke and fire detection systems and camera light meters. The structure is covered with glass sheet to protect it from moisture and dust and allows only light to fall on it. 1 Applications Lead sulfide (PbS) and indium antimonide (InSb) LDRs are used for the mid infrared spectral region. GeCu photoconductors are among the best farinfrared detectors available‚ and are used for infrared astronomy and infrared spectroscopy

Yoyo is a toy that everyone has played at some point in their lives. Yoyo is more than twenty five thousand years old. It is the second oldest toy‚ after dolls. The yoyo was first documented to be invented in Greece with wood‚ metal and terra cotta.2 .The disks were decorated with the pictures of their gods. The yoyo moved to the Orient around 1800. The yoyo was used as a weapon in Philippines. Their version was large with sharp edges and spikes attached to a twenty foot long rope for flinging at

Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1. The orbit of each planet is an ellipse which has the Sun at one of its foci. 2. Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3. The squares of the periods of revolution of

where μo is the permeability of free space and has the value of 4π x 10-7 N/A2‚ N is the number of turns of wire‚ I is the current through the wire‚ and R is the radius of the loop. When the wire loops of the tangent galvanometer are aligned with the magnetic field of the Earth‚ and a current is sent through the wire loops‚ then the compass needle will align with the vector sum of the field of the Earth and the induced field as shown in Figure 1.

8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between
