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
An atmosphere is a layer of gases surrounding a planet or other material body, that is held in place by the gravity of that body
A barometer is a scientific instrument used in meteorology to measure atmospheric pressure
simple machine
A simple machine is a mechanical device that changes the direction or magnitude of a force
wheel and axle
The wheel and axle is one of six simple machines identified by Renaissance scientists drawing from Greek texts on technology
Contact forces
In physics, a contact force, is a force that acts at the point of contact between two objects, in contrast to body forces
Unbalanced forces
In physics, a force is any interaction that, when unopposed, will change the motion of an object
free-body diagrams
In physics a free body diagram is a graphical illustration used to visualize the applied forces, movements, and resulting reactions on a body in a steady state condition
Free fall
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it
terminal velocity
Terminal velocity is the highest velocity attainable by an object as it falls through a fluid
hydrostatic pressure
Fluid statics or hydrostatics is the branch of fluid mechanics that studies incompressible fluids at rest
flow rate
In physics and engineering, in particular fluid dynamics and hydrometry, the volumetric flow rate, is the volume of fluid which passes per unit time; usually represented by the symbol Q
the equation of continuity
A continuity equation in physics is an equation that describes the transport of some quantity
A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum
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
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
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed
