Definition
change in velocity over time. Can be speed or direction. if remains the same no acceleration 


Term
Acceleration Due to Gravity (g) 

Definition
any free falling object's acceleration is 9.8 m/s^2
speed is proportional to time falling 


Term
Speed of Free falling body
S= a*t 

Definition
The speed of a falling body is directly proportional to the time the object has been falling. if the object is falling the acceleration is acceleration due to gravity (g)
speed= acceleration * time 


Term
Distance of Free Falling Body
D= 1/2 * a * t^2 

Definition
the distance of a free falling object is directly proportional to the square of the time the object has been falling for all cases of constant acceleration, if the object is falling, it is the acceleration due to g (9.8m/s^2)
distance= 1/2 acceleration * Time^2 


Term
Newton's Second Law
Fnet = m*a 

Definition
Acceleration is proportional to net force, but inversly proportional to the mass.
acceleration = Fnet/m Fnet = mass * acceleration
harder to move, more inertia, more mass 


Term

Definition
f net = f1f2 if forces are oppisite f net = f1+f2 if forces are the same

Definition
Acceleration is proportional to net force, but inversly proportional to the mass.
acceleration = Fnet/m Fnet = mass * acceleration
harder to move, more inertia, more mass 


Term

Definition
f net = f1f2 if forces are oppisite f net = f1+f2 if forces are the same
determines acceleration when objects not accelerating, Fnet must equal 0 


Term

Definition
on the surface of earth, force exerted by gravitational pull of earth on an object Tension = Weight
Weight= mass * gravity (9.8) 


Term

Definition
upward push. equal to its weight (downward push) 


Term

Definition
tension = weight
w= mg
so t= mg 


Term
Newton's 3rd Law The Law of Force Pairs 

Definition
when you push an object the object pushes back at you. 


Term

Definition

x= distance compressed or stretched 


Term

Definition
the momentum of an object of mass (m) moving with velocity (v) Vector speed w direction 


Term
Conversion of momentum (p) 

Definition
if there are no external forces, the total momentum is conserved (unchanged), regardless of parts acting upon each other 


Term

Definition
force due to gravity = weight (m*g) Newton said same force that holds moon in orbit that pulls apple from tree to ground. 


Term
Law of Gravitation
F gravity= g * m1*m2/r^2 

Definition
if mass doubles, G force doubles. if g force divided by 4 the separation of masses doubles
two forces get farther from each other G Force gets smaller
