Tomorrow's test covers work, energy, power, and impulse/momentum as well as conservation of energy and conservation of momentum. The topics you should be familiar with are listed below (although I cannot promise that this is an all-inclusive list):
Topics:
Be able to define a system and determine if it is isolated. Identify internal and external forces
Define work and calculate work done by a force
Apply relationships between work, net force, displacement, velocity, and energy to solve problems
Calculate the power of a system
Identify and calculate the mechanical energy of a system including gravitational potential energy, kinetic energy, and elastic (spring) potential energy
Identify the change in thermal energy of a system when friction is present in the system
Apply conservation of energy to analyze energy transitions and transformations within a system
Analyze the relationship between work done on or by a system, and the energy gained or lost by that system
Use Hooke’s Law to determine the elastic force on an object
Calculate a system’s elastic potential energy
Calculate the work done by a variable force from a force vs. displacement graph
Define and calculate the momentum of an object
Understand the relationship between impulse and change in momentum (Impulse Momentum Theorem)
Analyze situations involving average force, time, impulse, and momentum
