Chapter 11
A prefix meaning 1000.
What is kilo-?
The SI unit for force.
What is a newton?
The SI unit for pressure.
What is the pascal?
This SI unit for work.
What is a joule?
The ability to do work.
What is energy?
The ratio of the distance an object moves to the time it took to move.
What is speed?
Fish experience this type of friction.
What is fluid friction?
To calculate pressure, this value is divided by surface area.
What is force?
The SI unit for power.
What is a watt?
Potential energy + Kinetic energy.
What is mechanical energy?
The slope of a distance-time graph.
What is speed?
Two forces acting free fall.
This principle states that faster fluids have less pressure.
What is Bernoulli's Principle?
This term describes a device that changes the force put into an object/system.
What is a machine?
Einstein's equation, E=mc^2, describes the relationship between these two values.
What are mass and energy?
The rate at which velocity changes.
What is acceleration?
What is inertia?
This principle states that pressure is transmitted equally through all directions in a fluid in a closed container.
What is Pascal's Principle?
The efficiency of a machine is always less than this value.
What is 100%
This describes the chemical energy stored in living things.
What is biomass energy?
The slope of a speed-time graph.
What is acceleration?
Action and reaction forces are described by this law.
What is Newton's Third Law?
This principle describes the relationship between buoyant force and weight of displaced fluid.
What is Archimedes' Principle?
This type of device is made up of two or more simpler devices.
What is a compound machine?
Increasing temperature results in an increase of this type of energy.
What is thermal energy?
