Leaving Certificate Physics (Higher Level)
Sample material
On our rewrite days, and in the accompanying notes, the material is broken down in to key sections. For each topic we look at the compulsory Experiments, The Definitions, The Demonstration Experiments The Core Material.
On the following pages, we show near of the revision material we use for the section of the course relations with mechanics

Definitions
There is no specific list of definitions which must be learned for the exam. Many are mentioned in the syllabus, precisely others cause been asked in the past. To be certain of getting all attach for definitions (which will amount to 15% or more), it would be needed to learn a few hundred. The vast majority of what is apt(predicate) to be asked, however, is shown here. Energy is the ability to do work. Work is through when a forcefulness moves an object through a distance.
strength is i. ii. the rate at which work is done. the rate at which sinew is converted from one form into another.
Newtons Laws of act i. A bole will continue in a state of rest or of uniform velocity unless an harebrained external force acts upon it ii.
The rate of change of a bodys momentum is proportional to the force which causes it and takes place in the direction of that force. (F = ma) iii. If body A exerts a force on body B, then body B exerts an equal but opposite force on body A.
A force is anything which causes or tends to cause an quickening.
The momentum of a body is the harvest-feast of a bodys mass and velocity

Friction is a force which tends to oppose motion
The principle of conservation of momentum states that in any interaction between bodies, the total momentum in the beginning the interaction will equal the total momentum aft(prenominal) the interaction, provided no external forces act upon the bodies
Centripetal acceleration is the acceleration of a body in circular...If you want to get a full essay, order it on our website: Orderessay
