S&S Physics 3

Archimedes Principle states

• that an object immersed in a fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid

• the vector sum of the forces on an object is equal to the mass of the object multiplied by acceleration of the object.

• every action has an equal and opposite reaction.

• an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.

A heavy material, such as gravel, sand, iron, or lead, placed low in a vessel to improve its stability.

• matter

• ballast

• buoy

• mast

What is the power of supporting a body so that it floats; upward pressure exerted by the fluid in which a body is immersed.

• specific gravity

• density

• buoyancy

• displacement

Density is

• a force equal to mass multiplied by the acceleration due to gravity

• any substance that has mass and takes up space by having volume.

• the quantity of three-dimensional space enclosed by a closed surface

• mass of a unit volume of a material substance.

What is the change in position of an object, in space of one mass by another. the weight or the volume of fluid displaced by a floating or submerged body?

• diffusion

• displacement

• density

• buoyancy

A substance that continually deforms under an applied shear stress, or external force.

• ballast

• weight

• volume

• fluid

Fluid Mechanics

• is a branch of physics that is concerned with the response of fluids to forces exerted upon them,

• includes fluid dynamics

• includes fluid statics

• all of the above

A subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases.

• fluid mechanics

• fluid dynamics

• fluid statics

• fluidity

A subdiscipline of fluid mechanics that studies "fluids at rest and the pressure in a fluid or exerted by a fluid on an immersed body"

• fluid mechanics

• fluid dynamics

• fluid statics

• fluidity

Refers to the quantity or distance. In relation to the movement, can be correlated with size and speed of an object while travelling.

• buoyancy

• specific gravity

• pressure

• magnitude
