Term
 Archimedes Principle
Definition
 The relationship between buoyancy and displaced fluid: An immersed object is buoyed up by a force equal to the weight of the fluid it displaces.
Term
 Boyle’s Law
Definition
 At a constant temperature, the volume of a given quantity of gas is inversely proportional to the pressure upon the gas.
Term
 Buoyancy
Definition
 An upward force acting on an immersed or floating body by the supporting fluid.
Term
 Buoyant Force
Definition
 The net upward force exerted by a fluid on a submerged object.
Term
 Density
Definition
 A property of a substance, equal to the mass divided by the volume; commonly thought of as the lightness or heaviness of a substance.
Term
 Displaced
Definition
 Term applied to fluid that is moved out of the way when an object is placed in the fluid.
Term
 Elastic Potential Energy
Definition
 Potential energy due to tension – either stretch (rubber bands, etc.) orcompression (springs, etc.).
Term
 Energy
Definition
 The ability to do work. Appears in many forms, all of which are either kinetic or potential.
Term
 Equilibrium
Definition
 A state of balance between opposing forces.
Term
 Fluid
Definition
 Anything that flows; any liquid or gas.
Term
 Force
Definition
 A push or a pull. An influence on a body or system, causing or tending to cause a change in movement or shape.
Term
 Gravity
Definition
 A pulling force exerted by any mass upon another.
Term
 Inertia
Definition
 The tendency of matter to remain at rest if at rest, or, if moving, to keep moving in the same direction, unless affected by an outside (or unbalanced) force.
Term
 Kinetic Energy (KE)
Definition
 Energy of motion. Includes heat, sound, and light (motion of molecules).
Term
 Mass
Definition
 The amount of matter that is contained by an object.
Term
 Momentum
Definition
 The quantity of motion of a moving object, equal to the product of its mass and its velocity.
Term
 Neutral Buoyancy
Definition
 Exists when the weight of the body is equal to the weight of an equal volume of the displaced fluid. The body remains suspended – neither rising nor sinking – unless acted upon by an outside force.
Term
 Potential Energy (PE)
Definition
 Energy of position; energy that is stored and held in readiness. Includes chemical energy, such as fossil fuels, electric batteries, and the food we eat.
Term
 Pressure
Definition
 The force per unit of surface area; exerted perpendicular to the surface; measured in Pascals.
Term
 Principle of Flotation
Definition
 A floating object displaces a weight of fluid equal to its own weight.
Term
 Speed
Definition
 How fast an object is moving. The distance traveled over time.
Term
 Velocity
Definition
 The speed of something in a given direction.
Term
 Volume
Definition
 The amount of space enclosed by a shape or object; how much 3-dimensional space (length, width, and height) it occupies.
Term
 Weight
Definition
 The downward force caused by gravity on an object.
