movement
When two forces equal in size and acting in opposite directions on an object.
Continues to move at the same speed and in the same direction.
When two forces that are unequal in size and opposite in direction.
Causes objects to change position, direction or speed.
The overall or combination of all forces acting on a object.
Measured in Newtons (N)
position
, b)direction
, c)speed
change direction
, b)change speed
, c)change direction
applied force
object at rest tends to stay at rest unless acted by an unbalanced force
law of inertia
object in motions, tends to stay in motion, unless acted by an unbalanced force
The accerlation of an ojbect is dependent upon two variables, net force and the mas
Force = Mass X Acceleration
For every action there is an equal and opposite reaction
a rocket taking off
Newtons First First Law of Motion or Law of Inertia
Newtons 2nd Law of motion
constant speed
