What is density? Density is the ratio of mass to volume
What is buoyancy? The tendency of an object in a fluid to rise or sink due to density differences with its surroundings
What is Archimedes principle? The buoyant force on an abject is equal to the weight of the fluid displaced by the object
What is pressure? The amount of force applied to a given area
What are two effects of pressure? 1. It causes our ears to pop when we change altitude quickly 2. Air Balloon increases in pressure and explodes
What is parcels law? When force is applied to an enclosed fluid the increase in pressure is transmitted equally to all parts of the fluid.
What is a hydraulic system? Transfer of energy from flow and pressure, not from the kinetic energy of the flow.
What is compression? The decrease in volume as a result of a force
What is a pneumatic system? A system that uses a gas, usually air, under pressure to transmit a force
What is buoyant force? s an upward force exerted by a fluid that opposes the weight of an immersed object.
