the process of changing position
motion
the starting point used to describe the motion or position of an object
reference point
the total length of your path of motion
distance
the distance between your final and starting postion
displacement
distance divided by time =
speed
the speed and direction of an objects motion
velocity
end speed-start spped divided by time =
acceleration
a push or pull that an object exerts onto another object
force
is a push or pull on an object by another object that is touching it
contact
a push or pull on and object by another object without touching it
noncontact
a contact force that resists the sliding motion between two objects that are touching
friction
the noncontact attractive force existing between all objects with mass
gravity
0 newtons
balanced
15N to the left is a ________ force
unbalanced
the sum of all forces acting on an object
net force
the tendancy of an object to resist an change in its motion
inertia
when two objects exert forces on eachother
force pair
Newton's ______ law explains the effect of balanced forces of an object
first
Newton's _______ law states that the acceleration of an object equals the net force excerted on an object divided by its mass
second
Newton's ____ law states that when one object exerts force on a second object exerts o force the same size but in the opposite direction of the first object
third
