38 Terms
weight
force an object exerts on a support surface
elastic collision
characterized without lasting deformation
friction
resists motion
force pair
action and reaction resulting from an interaction
terminal speed
when air resistance stops gravitational acceleration
inelastic collision
characterized by lasting deformation, or sticking
satellite
a smaller body that orbits a larger body
vector
described by a magnitude and a direction
mass
a measure of inertia / amount of matter
free fall
motion under the influence of gravity only
acceleration
- changing velocity over time
- meters / second ^2
projectile
an object that moves through the air under the influence of gravity
interaction
mutual action between objects
escape speed
requisite requirement to escape gravitational influence
potential energy
results from an object's position
inertia
the property of an object that resists change in motion
newton
a unit of force
kilogram
SI unit of mass
velocity
- speed in a particular direction
- distance / time
newton's 1st law
the law of inertia
newton's 2nd law
force = mass x acceleration
newton's 3rd law
deals with equal and opposite forces
work
transfer in energy fue to force
momentum
inertia in motion
energy
property of a system that allows it to do work
parabola
the path curved out by a projectile without air resistance
ellipse
general shape for the path of a satellite
aristotle
- logic
- treated motion by dividing it into two classes (natural motion and violent motion)
- natural state of rest
galileo
- experiment
net force
the combination of all forces that act on an object
support force
the force that supports an object against gravity
normal force
terminal velocity
terminal speed in a given direction (often downward)
conservation of energy for machine
the work output of any machine cannot exceed the work input
conservation of energy
energy cannot be created or destroyed, only transformed
efficiency
the percentage of the work put into a machine that is converted into useful work output
impulse
the product of the force acting on an object and the time during which that force acts on that object
kinetic energy
the energy an object possesses due to its motion
