Transcript of Aerodynamic. able to move through the air with as little air resistance as possible.
aerodynamic
able to move through the air with as
little air resistance as possible.
air resistance
the force of friction on a vehicle
as it moves through the air.
axle
a bar or shaft on which a wheel turns.
blueprint
a detailed plan of drawing that shows how something is designed.
constant
a condition that is not changed
in a scientific experiment.
cost-effective
able to produce the best results
for the least money.
data
information, such as that gathered
during an experiment.
drag
force that opposes the
forward movement of a vehicle.
dynamics
the part of physics that deals with how things move and the forces that change
their motion.
energy
the ability to do work or to make
something happen.
force
push or pull.
friction
force that resists movement
between two objects that are touching.
gravity
a natural force that draws things toward the earth’s surface.
inclined plane
a ramp or slanted surface.
inertia
an object’s ability to remain at rest or in motion until a force acts upon it.
kinetic energy
energy associated with motion.
laws of motion
three laws, formulated by Sir Isaac Newton, that describe how objects move in relation
to the forces acting on them.
lever
a bar or board resting on a support (fulcrum).
mass
the amount of matter an object has.
momentum
the speed or force that a moving object has because of its weight or motion.
potential energy
stored energy that can be
released to become other
forms of energy.
prototype
an original model or design.
pulley
a grooved wheel with a rope around it.
screw
an inclined plane wound around a cylinder.
simple machine
a machine with few or no moving parts.
speed
a measure of how fast
something is moving.
technological design
the process of designing and building products and systems to meet human
needs.
tension
the force exerted by a stretched
object, such as a spring.
three-view drawing
a diagram, showing top,
side, and front views.
variable
an element in an experiment
than can be changed.
wedge
two inclined planes put together to form a narrow cutting edge.
weight
a measurement of the force of
gravity on an object.
wheel
and axle
a simple machine. It consists of a
wheel that turns an axle,
or an axle that turns a wheel.
