newtons law

Cards (12)

balanced forces cancel each other out
unbalanced forces cause a resultant force to act on an object
what is newtons first law?
an object will remain rest or at a constant velocity unless it is acted upon by a external resultant force
what is weight  
the force of gravity acting on a object
what is mass  
the amount of matter in a object
what is the equation of weight
mass x gravitational field strength
if the forces are not balanced then the motion of the object will change
what is newtons 2nd law
can calculate the acceleration or deceleration
what is the equation for resultant
mass x acceleration
what is newtons 3rd law
if body A exerts a force on body B, body B will exert an equal and opposite force
what is terminal speed?
as something falls the forces will be opposite
what is force measured in?
newtons
