Physics Ch.2&3
Divided into
Chapter 2: Accelerated motion
Consist of
2.1: Definition
Which is
Change in the velocity of an object
2.2: Calculate
Which is
a=change in velocity/time
2.3: Unit
Which is
m/s^2 or ms^-2
2.4: Deducing
Which is
Gradient of velocity-time graph/ time
2.5: Displacement
Whixh is
The measuring of how far and which direction the object goes
2.6: Acceleration sensor
Which is
A sensor used to detect crashes and inflate airbags or detect swerves and activates stabillity control
2.7: Laboratory
We can use
Stopwatches
Ticker Timers
Light Gates
2.8: Suvat
Equation 1: v=u+at
Equation 3: s=ut + 1/2at^2
Equation 4: v^2=u^2 + 2as
Equation 2: s=(u+v)/2 x t
2.9: Deriving Suvat equations
from
a=(v-u)/t
to be
Equation 1
from
(u+v)/2
to be
Equation 2
from
Equation 1 +2
to be
Equation 4
Equation 3
2.10: Uniform and non-uniform acceleration
Divided into
Uniform
Constant Acceleration
Non-Uniform
Not Constant acceleration
2.13: Projectiles
Consist of
Y-Cartesian line (Accelerated motion)
Consist of
Uy=Usin(tetha)
Tpeak: Uy/g
X-Cartesian line (Constant speed)
Consist of:
Ux=Ucos(theta)
Smax= Ux x t
Others
include:
Smax: u^2 x sin2(tetha)/g
Hmax= u^2 x sin^2(tetha)/2g
2.12: What is g
G is..
gravity
Earth: 9.81m/s^2
2.11: Acceleration by gravity
Which is
v=gt^2
s=1/2gt^2
v^2=2gh
Chapter 3: Dynamics
Consist of:
3.1: Force, Mass, & Acceleration
Which is:
F=ma
a=F/m
m=F/a
3.2 and 3.3: Identifying forces
They are:
Push and pull
Pushing and Pullng accelerations
Weight
mass x gravity
Frriction
Rubbing of two surfaces
Drag
Resistence of medium
Upthrust
Force to float in medium
Contact force
Force made upon contact with another object
Tension
Rope or string when stretched
3.4: Mass and Inertia
That is...
Inertia: The resistance of an object to change its velocith
The more mass=more inertia
Balanced forces = (F = opposite F) = Terminal Velocity = Top speed
Unbalanced forces = (F >< opposite F) = accelerate
3.5: Moving through fluids
They are...
Water
Drag
Solution:
Streamlined-postured objects
Smooth surfaces
Air
3.6: Newton's third law of motion
''For every action, there is an equal and opposite reaction''
3.7: SI units
Consist of...
Length (metre)
Mass (kilogram)
Time (seconds)
Electric current (Ampere)
Temperature (kelvin)
Amount of substance (moles)
light intensity (candela)
