1
New cards
mass is
constant
2
New cards
weight is based on
gravity
3
New cards
force
push or pull on object
4
New cards
force is measured in
newtons
5
New cards
can measure force with
force meter or spring scale
6
New cards
gravitational force
exerted by gravity on objects
7
New cards
mass
amount of matter in it
8
New cards
mass is measured in
kg, grams, milligrams
9
New cards
we use ________ to measure mass and compare the pull of gravity on standard masses
balances
10
New cards
when does mass change
the amount of particles
11
New cards
weight is a
force
12
New cards
force of _______ exerted on mass
gravity
13
New cards
1kg =
9\.81 newtons
14
New cards
gravitational force depends on
distance of objects
15
New cards
object weight changes on
where it is
16
New cards
formula
weight (n) = mass times gravitational force (m/s2)
17
New cards
mass x gravity =
weight on a planetary object
18
New cards
imaginary point where mass is
evenly distributed
19
New cards
stability is where
the point is
20
New cards
structures that have a low center of gravity and wide base are
stable
21
New cards
stresses act on
outside of the structure
22
New cards
stresses act on outside of the structure cause
internal forces
23
New cards
dead load
permanent force acting on structure
24
New cards
live load
changing force acting on structure
25
New cards
impact forces
type of live load
26
New cards
internal
within the structure
27
New cards
tension
strech/pulling
28
New cards
tensile strength
stand before breaking
29
New cards
compression forces
squeezing
30
New cards
compressive strength
stand before breaking or loosing shape
31
New cards
shear forces
bending, tearing, or pressing in opposite directions at the same time
32
New cards
shear strength
before ripping apart
33
New cards
torsion forces
Turing opposite sides
34
New cards
torsion strength
spring back to normal shape
35
New cards
bending force
combo of compression and tension
36
New cards
force will cause
structures to fail
37
New cards
lever
something that with enough force will move
38
New cards
external is added to lever it will be able to lift
a heavy load
39
New cards
unintentional lever
can cause damage
40
New cards
strong wind can
exert external force that bends frame
41
New cards
fulcrum
point where beam of lever pivots
42
New cards
external force
pushes down on one side and pushes up against load. it will weaken
43
New cards
solid materials have
cracks or weaknesses
44
New cards
when compressed
cracks can enlarge
45
New cards
section of compressed material may
sheer or slide over another area
46
New cards
compression force can cause it to
bend and buckle inside and pull and snap outside
47
New cards
brittle structure will shear when
twisted
48
New cards
flexible structure will shear when
twisted
49
New cards
flexible structures fold, twist, tangle into knots causing it to
lose its shape
50
New cards
when metal is twisted a lot and then weaken it will
cause it to fail
51
New cards
some panels are meant to buckle in certain places when
pressed on
52
New cards
car bumper in collisions are supposed to
absorb energy
53
New cards
mechanical device to prevent
failure in the motor
54
New cards
break/shears protect
the motor
55
New cards
twisted yarn/fibers are stronger than
one singular fiber
