|
As the angle between two concurrent forces decreases, (resultant)
|
the resultant force increases
|
|
|
As the angle between two concurrent forces decreases, (force required to produce equilibrium)
|
the magnitude of the force required to produce equilibrium increases
|
|
|
As angle increases, the horizontal acceleration of the mass
|
decreases
|
|
|
As mass increases, the inertia
|
increases
|
|
|
Newton's Third Law
|
Every action has an equal and opposite force.
-A single force can't exist in nature- when object 1 exerts a force on object 2, object 2 exerts a forces equal in magnitude and opposite in direction on object 1 |
|
|
Newton's First Law
|
an object's state of motion will not change unless an unbalanced force acts on it. It will accelerate it.
|
|
|
The greater the force applied to an object,
|
the more it accelerates
|
|
|
the greater the object's mass,
|
the less it accelerates
|
|
|
what's the acceleration equation?
|
a = fnet/m
|
|
|
what does forces change?
|
-forces change the magnitude and/or direction of an object's motion.
|
|
|
What's another word for Newton's First Law?
|
Inertia
|
|
|
Net force
|
resultant (vector sum) of all forces acting on an object
|
|
|
What does a force do?
|
-A force changes the state of motion of an object
-A force changes an object's velocity -A force accelerates an object- slow/fast; change direction |
