Recall…
•
Chapter 2:
Newton’s 1
st
law, inertia, equilibrium (sum of forces = 0)
•
Chapter 3:
Linear motion, speed, velocity (= speed with direction), acceleration(= rate
of change of velocity), free-fall motion (
a = g)
•
Chapter 4:
N’s 2
nd
law, Fnet =
ma
, weight =
mg
, weight vs mass, friction, non-free fall
and air resistance, terminal velocity
•
Chapter 5:
N’s 3
rd
law, action-reaction, vectors
•
Chapter 6:
Momentum(= mv), Impulse=
F t
= change in momentum,
external vs
internal forces, momentum conservation when Fnet on system =0, collisions
•
Chapter 7:
Energy, Kinetic energy = ½
m v
2
, Potential energy, Grav. PE =
mgh
, Work
=
F d
,
change in KE = Work,
Power = Work/time, Total energy conservation,
machines
•
Chapter 8:
Rotation, linear/tangential speed vs angular/rotational speed,
v = r
ϖ
,
rotational inertia
I
,
torque =
F
x lever arm, angular momentum =
I
ϖ
, ang mom
conservation, CM/CG, stability
•
Chapter 9:
Gravity: F= Gm
1
m
2
/d
2
, weight = force exerting against supporting surface,
tides, black holes
