4.5-6.3

fluid friction that tends to slow an object moving through a fluid, including air resistance

what are the four main factors affecting drag

the science of shaping objects to allow the smooth flow of fluids around them and reduce drag

the force on an object that is generated by relative motion between the object and a fluid and is perpendicular to the direction of fluid flow

a structure designed to produce lift as it moves relative to a fluid

the phenomenon of a spinning cylinder or ball causing lift

states that lateral (sideward) pressure exerted by a moving fluid decreases as the fluid’s speed increases

the ability to do work and change matter

the unit of energy

energy of motion

energy associated with the position of an object and the forces acting upon it

energy from motion or forces that affect a whole object

the law stating that energy can neither be created nor destroyed, only transferred

who discovered that mass and energy can be considered two different ways of measuring the same physical property

law stating that the total mass and energy is constant

the simplest form of kinetic energy; the energy of an entire object moving

what are the four factors affecting rotational kinetic energy

any of the four natural forces that cause potential energy

the attractive force between all material objects

potential energy caused by the restorative forces when an object is deformed

the second-strongest fundamental force, which affects only objects with an electric charge

a force that affects certain subatomic particles; stronger than the gravitational force but weaker than the electromagnetic force

the strongest fundamental force, which acts only within atomic nuclei and combines subatomic particles together to form the nucleus of an atom

the energy resulting from the chemical combination of atoms into molecules
