Name of his book
Principia
acceleration
center seeking force that causes objects to travel in a curved path
centripetal
work output should be equal to this in ideal conditions
work input
distance between 2 ridges on a screw
pitch
His 1st law of motion
law of intertia, objects only move if acted upon
acceleration of gravity at the earth's surface
9.81 m/s2
SI unit of power
watts
a vector has what 2 things
magnitude and direction
"circular lever"
wheel and axle
2nd law of motion
F=ma, the force required to accelerate an object at a certain rate equals the object's mass times the desired acceleration
a vector showing an objects change in position
displacement
Gravitational force exerted on an object near the surface of the earth
gravity
SI unit of force
Newton
resembles an inclined plane wrapped around a rod
screw
3rd law of motion
for every action there is an equal and opposite reaction
quantity of motion
momentum
any two objects attract each other with a force that depends on their masses and the distance between them
law of universal gravitation
force of air resistance equals the objects weight during free-fall
terminal velocity
special form of inclined plane that modifies force and directs it to the side
wedge
Galileo
the resistance to motion
friction
Distance traveled in a given time
speed
Vector showing the combined effect of 2 or more vectors
resultant
combination of fixed and movable pulleys
block and tackle
