4 Questions
Match the following definitions with their corresponding terms:
Mechanical advantage = The amount by which a machine can multiply an input force Efficiency = The useful work done by the machine compared to the work needed to operate it Potential Energy = An object can store its energy to do work later Friction = When two objects rub and push against each other, they create the force known as friction
Match the following concepts with their examples:
Kinetic Energy = When an object is moving, the energy it has is called kinetic energy Mechanical system = Any mechanical system that reduces the force required to accomplish work Work = The amount of effort spent when a force causes an object to move a distance Input force = Sometimes called the effort force
Match the following units/symbols with their corresponding terms:
Joules = Unit for Work Newtons = Unit for Force None = Unit for Efficiency D (meters) = Distance in Work formula
Match the following categories with their descriptions:
Contact forces and at-a-distance force = Two different groups forces can be categorized into Simple machines = Includes pulleys, wheel and axles, levers, inclined planes, screws, and wedges Mechanical advantage vs. Ideal mechanical advantage = Difference between a number telling how many times a simple machine multiplies the effort force
