Unit 4.2: Work & Power
ESSENTIAL IDEA:
Work is the transfer of energy that occurs when a force is applied through displacement.
Work is the transfer of energy that occurs when a force is applied through displacement.
UNDERSTANDINGS/APPLICATIONS/SKILLS/NATURE OF SCIENCE:
4.2.U1: Quantities can be classified as scalar or vector quantities
4.2.S1: Calculations of speed and acceleration, and distance and displacement
4.2.U2: A force is any interaction that, when unopposed, will change the motion of an object
4.2.S2: Calculating force
4.2.U3: A force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force.
4.2.U4: Power is the rate of doing work
4.2.A1: Calculate the work and power in real world applications.
