Simple machines are extremely important to everyday life. They make stuff that is normally difficult a piece of cake. There are several types of simple machines. The first simple machine is a lever. A lever consists of a fulcrum‚ load‚ and effort force. A fulcrum is the support. The placing of the fulcrum changes the amount of force and distance it will take in order to move an object. The load is the applied force. The effort force is the force applied on the opposite side of the load

when an individual is exposed to quality interaction with the world in which they belong. ( and the individuals quality interaction with that situation that enables for the development of a sense of belonging.) Within Steven Herricks novel “ the simple Gift” the passage of time for the protagonist Billy is cherished during his stay in Bendarat and Billy interacts with the town and it’s people with the utmost respect to maintain his sense of belonging in the town.

and their surroundings. This is clearly seen in The Simple Gift by Stephen Herrick which demonstrates elements of belonging and acceptance through the ’pain and suffering’ of rejection‚ ’homelessness’ and ’dealing with death’ by the characters Billy‚ Caitlin and Old Bill. Similarly in the movie “Freedom Writers”‚ it explores the ideas of taking control of one’s identity and accepting life’s simple pleasures. Firstly‚ in the novel ‘The Simple Gift’‚ Steven Herrick explores the idea taking control

Physics 1 – Mechanics and Heat Lecture Notes Prepared by: ENGR. HAROLD JAN R. TERANO‚ ECE Lesson 5 ROTATIONAL KINEMATICS AND DYNAMICS Uniform Circular Motion – an object moves at a constant speed along a circular path. Velocity is always tangent to the path in circular motion. Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration
