Aristotle categorized motions as ________________________?
either natural or violent
26
Galileo's View on Vertical Motion
Objects move downward because gravity disturbs their motion
27
An object's rate of fall is NOT dependent on its mass but primarily by gravity and air resistance
Galileo's View on Vertical Motion
28
(Galilean Vertical) In the absence of a resistance, object would _________________.
not fall depending on their weight, but in the time of fall
29
(Galilean Vertical) If the object encountered a resistive force from a fluid equal or greater than its weight, _________________.
it will slow down and reach uniform motion
30
A stone dropped in the ocean will sooner or later travel at constant speed.
Galileo's View on Vertical Motion
31
Aristotle's View on Projectile Motion
projectile will move in a straight diagonal line until energy is gone and will fall back straight down
32
Galileo's View on Projectile Motion
projectile will move in a curved path
33
curved path which is a combination of constant horizontal speed and constant vertical acceleration
Galileo's View on Projectile Motion
34
Aristotle’s View of Motion
motion of an object depends on the element that composes it (earth, air, fire, water)
35
Galileo's View of Motion
all objects moved depending on the forces acting on it
36
Stated that the Earth is attracted to the apple and vice-versa.
Isaac Newton
37
Formulated the laws of universal gravitation and laws of motion.
Isaac Newton
38
Newton's First Law
Inertia
39
An object will remain at rest and in motion unless acted by an external or unbalanced force.
Inertia
40
Newton's Second Law
Acceleration
41
An accelerated body is directly proportional to the force applied on an object and inversely proportional to the mass of the object.
Acceleration
42
Law of acceleration formula
f=ma
43
mass in motion
Momentum
44
large mass & large velocity = ?
large momentum
45
large mass & less velocity = ?
large momentum
46
less mass & large velocity = ?
large momentum
47
less mass & less velocity = ?
less momentum
48
force that acts in a particular time which causes the momentum of an object to change
Impulse
49
change in momentum
Impulse
50
Impulse-Momentum Theorem
Impulse = momentum
51
Newton's Third Law
Interaction / Action reaction
52
For every action, there is an equal but opposite directed reaction
Interaction / Action reaction
53
Law of Conservation of Momentum
total momentum before collision equals to total momentum after
54
Elastic Collision
kinetic energy and momentum is conserved
55
collision where carts bounce/separate
Elastic
56
Inelastic Collision
kinetic energy is not conserved but the momentum is conserved
57
collision where carts are attached/attracted
Inelastic
58
Studies the position, acceleration and speed of an object without regard to mass

59
Describes motion using equations of motion
Kinematics
60

Scalar
64
Displacement, Velocity and Acceleration
Vector
65
always positive
Scalar
66
can be positive or negative

69
Vertical upward motion
Type of motion that has a vertical upward path
70
Final velocity of vertical upward motion
0
71
Motion that is under the influence of Gravity
Free fall
72
Gravity acts on a motion along two dimensions, combining uniform velocity (x) and acceleration (y).
Projectile Motion
73
Uniform Speed or Velocity
object covers a similar distance in equal time intervals
74
Non-Uniform Speed or Velocity
the object travels a dissimilar distance at equal intervals of times.
75
Average Speed or Velocity
total distance/displacement divided by the total time taken
76
push and pull
Violent Motion
77
straight up or down
Natural Motion
