A
joules
unit of everything
velocity
the distance something goes in a certain direction
force
push or pull on an object
speed
how fast something goes
friction
what makes an object stop
work
f x d = w
acceleration
how fast the speed is climbing
balanced forces
forces pushing or pulling on an object the same amount
velocity graph
shows the velocity of an object
applied force
distance
how far something goes
constant velocity
change in one direction constantly
unbalanced forces
uneven force being put on an object
acceleration graph
sir Isaac newton
English mathematician who created the laws of motion
constant speed
when the speed of an object stays the same
constant acceleration
speed increasing constantly
net force
sum of all forces on an object
net force formula
d x f = w
newtons 1 law
object at rest will stay at rest until act done by an unbalanced force
no speed
when something isn't moving
increasing acceleration
speeding up quickly
work formula
f x d = w
average speed formula
average off all the speeds
newtons 2 and 3 law
acceleration of an object depends upon the mass of an object and for every action there is an opposite and equal reaction
