Physics notes Force is an agent which produces or tends to produce motion in an object‚ stops or tends to stop ‚ motion of an object Newton’s 1st law of motion: If an object is at rest‚ will remain at rest until or unless an external force act on it. If an object is in motion ‚ it continues its motion until or unless an external force act on it Newton’s 1st law of motion is also called first law of inertia. Inertia: The tendency of an object to resist any change in its state of motion

Required Vocabulary – IB 12 Higher Level Physics and Physical Measurement 1. Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) If you push for an hour against a stationary wall‚ you do no work A) on the wall. B) at all. C) both of these D) none of these 2) If you push an object twice as far while applying the same force you do A) twice as much work. B) four times as much work. C) the same amount of work. 3) If you push an object just as far while applying twice the force you do A) twice as much

amount of Charge‚ Q that passes a point in a set time‚ t. It is measured in Amps (A)‚ and charge is measured in Coulombs (C). Since Amps are SI base units‚ Coulombs are defined as A×s‚ As. Voltage * Voltage (V) or Potential Difference (p.d.) is a measure of the Energy transferred per Charge Carrier between two points. * Voltage is the Energy‚ E per Charge‚ Q. Voltage is measured in Volts (V)‚ which is defined as one Joule per Coulomb. Voltage can be defined in base units as Kgm2s-3A-1. Power

The second law can also be stated in terms of an object’s acceleration. Since the law is valid only for constant-mass systems‚[16][17][18] the mass can be taken outside the differentiation operator by the constant factor rule in differentiation. Thus‚ [pic] where F is the net force applied‚ m is the mass of the body‚ and a is the body’s acceleration. Thus‚ the net force applied to a body produces a proportional acceleration. In other words‚ if a body is accelerating‚ then there is

Cocker and Walton Prizes 2012 Physics in Medicine By Fayaz Rahaman ➢ Introduction Physics is about understanding the laws that govern the world around us. Most people know about the problems solved and the discoveries made by physicists in the past‚ such as the orbits of planets found by Galileo‚ the law of gravity first unravelled by Newton and later extended by Einstein. It is not as widely

Health and Safety Measures Construction safety net also called scaffold net‚ debris net‚ safety net and so on. It is a safety device used to prevent injuries on or around a construction site. In the construction of multistory buildings it is necessary to install temporary vertical safety barriers at the edges of the various floors to prevent tools and construction materials such as rods‚ bricks‚ pipes and nails from falling from the floors and endangering people and property on underlying levels

ROA‚ ANNA MARIA D. BA PSYCHOLOGY 1 Physics and Psychology—Relationship Status: It’s Complicated but Related One way or another‚ all things in life are related to one another. The same goes with Physics and Psychology. These two Sciences are different in a lot of ways but are also similar in certain aspects. Physics is the branch of Science concerned with the nature and properties of matter and energy. Psychology‚ on the other hand‚ is the scientific study of the mind and its functions
