Motion,
An object that is moving in any direction
Force,
The hydraulic system of a dump truck is designed to multiply _______.
Gravity,
Gas particles exert pressure on earth due to what
Weight,
wt
A measure of the force of gravity on an object
Speed,
S=D/T
Velocity,
Distance/tim
Acceleration,
rate of change of velocity (vector)
Newton's 1st law,
an object that is in motion tends to stay in motion and an object in rest tends to stay in rest - unless stopped by some force (a ball that is kicked will eventually hit the ground due to the force of gravity)
Inertia,
The tendency of an object to resist changes in motion
Newton's 2nd law,
acceleration depends on the mass of an object being moved and the amount of force that is acting on an object. Formula: m?a
Newton's 3rd law,
for every action there is an equal or opposite reaction (when you jump on a trampoline you will bounce back up - when you high five, your hand goes backwards)
Balanced Forces,
Forces of equal magnitude, but in opposite direction.
Unbalanced Forces,
An individual force that is NOT being balanced by a force of equal magnitude and opposite direction
Friction,
a force that opposes motion between two surfaces that are in contact
Work (W),
Managed care phar tech
Simple Machine,
A device that either multiplies or redirects a force.
Mechanical Advantage (MA),
Mechanical Advantage= output force/input forc
Efficiency,
the percentage of the input work that is converted to output work.
Power,
Work done per unit tim
Kilograms
the SI unit of mass, equivalent to the international standard kept at S�vres near Paris (approximately 2.205 lb).
Newtons,
an object that is in motion tends to stay in motion and an object in rest tends to stay in rest - unless stopped by some force (a ball that is kicked will eventually hit the ground due to the force of gravity)
Watts,
W/cm^2
Joules.
Heat is measured in what?
