viscosity
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress

wheel and axle
The wheel and axle is one of six simple machines identified by Renaissance scientists drawing from Greek texts on technology
Got it
simple machine
A simple machine is a mechanical device that changes the direction or magnitude of a force
Got it
inclined planes
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load
Got it
Power

Power is the amount of work done in the time it takes to do it

Got it
potential energy
In physics, potential energy is energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors
Got it
kinetic energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion
Got it
Galileo Galilei
Galileo Galilei was an Italian astronomer, physicist, engineer, philosopher, and mathematician who played a major role in the scientific revolution of the seventeenth century
Got it
scalar quantity
A scalar in physics is a physical quantity that can be described by a single element of a number field such as a real number, often accompanied by units of measurement

Motion
In physics, motion is a change in position of an object with respect to time
Unbalanced forces
In physics, a force is any interaction that, when unopposed, will change the motion of an object
Free fall
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it
Sliding friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other
work
In physics, 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
time period
Frequency is the number of occurrences of a repeating event per unit time
lever
A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum
pulley
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taught cable, rope or belt along its circumference
screw
A screw is a type of fastener, sometimes similar to a bolt , typically made of metal, and characterized by a helical ridge, known as a male thread or just thread
compressibility
In thermodynamics and fluid mechanics, compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure change
pressure
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed
surface tension
Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible
