Physics Forces Review
Definitions
Old Motion Vocab Set
Formulas / Formulae
W = mg
F_{NET} = ma
F_{f} = µW
F_{NET} = F_{object}  F_{f}
Δd = 0.5at² + V_{i}t
V_{f}² = V_{i}² + 2aΔd
V_{f} = V_{i} + at²
a = ΔV / t
V_{AVG} = Δd / t
g = 10ms^{2} 9.8ms^{2}
m = mass
F_{f} = Friction Force
For equations, sorry, you can't really have a Quizlet set for them, but here are some tips for memorizing equations. First, you can try writing down the equation several times. Also, you can try saying it out loud, or visualizing the shape of it. Lastly, this one works the best for me, try using the equation as much as possible in your practice problems so that you remember them.
 Newton's First Law  An object at rest tends to stay at rest and an object in motion tends to stay in motion at a constant velocity unless acted upon by an unbalanced force.
 Newton's Second Law  The acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and inversely proportional to the mass of the object
 Newton's Third Law  Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
 Newton's 1st Law  An object tends to stay at rest or stay in motion at the same speed, unless something else makes it do something else
 Newton's 2nd Law  F=ma
 Newton's 3rd Law  For every action there is an equal and opposite reaction

Newton's Third Law
I know it's the same thing, but doesn't it make more sense to say
"For every action there is an equal and opposite reaction" ?
"For every action there is an equal and opposite reaction" ?

Yea, I'll fix that
