EmSAT Physics Achieve(General Track)Total Time for Test: 1.5 hourEmSAT Physics Achieve (Advanced Track) is a computer‐based test and has 4 major sections –Physics Foundations, Energy‐ Transmission, Energy ‐ Waves, Force and Motion‐Objects. Testsections, questions, and options are randomized. Sections and subsections of the test are timedby the computer. Test takers can see how much time they have throughout the test.Part 1: Physics Foundations ‐ Able to recognize vector quantities use them to solve problems Solve problems using scalar multiplication ofvectors Solve problems using addition or subtractionof vectors Solve problems using linear combination ofvectors Translate a vector Find the magnitude of a vectorMOE‐OD‐EMSAT‐02 Calculate the magnitude and direction of avector Find the dot product Find the angle between two vectors Use the dot product to find perpendicularvectors Find the components of a vector Find the component of a vector alonganother vectorVersion: 01Issue date: 20/NOV/2016

Part 2: Energy‐Transmission ‐ Describe transmission of various forms of energyo Understand that heat moves inpredictable ways, flowing from warmerobjects to cooler objects until both reachthe same temperatureo Know that heat can be transferredthrough matter by the collisions ofatoms and/or molecules (conduction) orthrough space (radiation)o Understand during a phase change, heatenergy is absorbed or releasedo Understand that most substances expandwhen heated and contract when cooledo Know that temperature affects thesolubility of some substances in watero Know the energy cannot be created ordestroyed, but only changed from one forminto anothero Understand that energy can changefrom one form to another, although inthe process some energy is alwaysconverted to heatMOE‐OD‐EMSAT‐02Version: 01o Understand all energy transfers aregoverned by the law of conservation ofenergyo Understand that energy may be convertedamong mechanical, electromagnetics,nuclear, and thermal formso Know that potential energy is the energyan object possesses by its position orcondition such as gravitational and elastico Know that kinetic energy is the energy anobject possesses by its motiono Understand an ideal mechanical system isthe sum of the macroscopic kinetic andpotential energies is constanto Understand when work is done or by asystem, there is change in the total energyof the systemo Understand that work done against frictionresults in an increase in the internal energyof the systemo Know that power is the time‐rate at whichwork is done or energy is expendedIssue date: 20/NOV/2016
