cos(30)

25
cos60
1/2
26
displacement
vector quantity of distance. path independent and is determined by the change in location from starting point. walking in a circle would result in a displacement of zero.
27
velocity
displacement over time. units: m/s
28
acceleration
velocity over time units: m/s^2 or V/t
29
if you have a positive velocity how would you interpret if the acceleration was.. A. positive B. zero c. negative
A. the object is moving up and speeding up more and more B. the object is moving up at constant speed C. object is moving upward and slowing down
30
if you have a 0 velocity how would you interpret if the acceleration was... A. positive B. zero C. negative
A. object is beginning to move upward from rest , or is moving from downward to upward B. object is not moving c. object is beginning to move downward from rest
31
if you have a negative velocity how would you interpret if acceleration was.. A. positive B. zero C. negative
A. object is moving downward and slowing down B. object is moving downward at a constant speed C. object is moving downward and speeding up
32
what does the slope of a displacement vs time graph represent
velocity. the steepness indicates speed - upward and downward indicate direction
33
what does the area under the curve of an acceleration vs time graph represent?
velocity 1/2(b*h)
34
major assumption for kinematic problems on MCAT?
constant acceleration
35
distance kinematic equation using velocity and time (no acceleration)
d = 1/2 (Vi+Vf)*t
36
distance kinematic equation with no final velocity?
d = Vit + 1/2at^2
37
final velocity kinematic equation with no displacement
Vf = Vi + at
38
final velocity equation with time missing?
Vf^2 = Vi^2 + 2a(delta d )
39
assumption in free fall problems
constant acceleration g = -9.8 m/s^2 - no initial velocity!
40
for projectile motion problems when does Vy = 0
when the object reaches its peak
41
what is the definition of force?
an objects mass times its acceleration units : N derived : Kg*m/s^2
42
types of force on the MCAT
1. gravitational (@ a distance) 2. electromagnetic (between charges) 3. contact 4. normal (against gravity) 5. friction 6. tension (rope). 7. centripital 8. spring (using hooke's law)
43
Newton's first law
statement on inertia object at rest will stay at rest unless acted upon, and an object in motion will stay in motion at a constant velocity unless acted upon
44
newton's second law
F= m*a
45
newton's third law
force pairs exert force on eachother equally and opposite F a on B = -F B on A
46
center of mass
X center = (m1X1 + m2X2) / (m1 + m2)
47
friction
force that opposes horizontal motion can be static (Fs) or moving (Fk) equation for static: Fs*N equation for kinetic: Fk*N
48
terminal velocity
highest velocity of an object obtained while traveling through a fluid (can no longer accelerate)
49
how do you calculate the x component of force of gravity on an incline plane?
Fsin(theta)
50
force of gravity equation
Fg = G (M1M2) / r^2
51
centripetal acceleration
a = v^2/ r
52
centripital force
mv^2/r
53
hooke's law
-Kx= Force of spring k is a constant unique to each spring
54
torque definition and equation
torque is rotational force (at a distance) T = F * d sin(theta)
55
what are the ways to increase torque?
increase force increase distance
56
rotational potential
t = f*d t = mg*d
57
work
force over a distance W= f*dcos (theta) unit: J or N*m - conservative force (independent of path)
58
mechanical advantage
on a slope, allows for less force with same work length of slope/ height of slope
59
power
work done over time P= w/t also p = V*f watts
