Download What makes one thing more energy efficient than another. Energy

The difference
between potential
and kinetic energy
Potential energy is
the energy
processed by its
position to others,
stress with itself,
electric charges, and
other factors. Kinetic
Energy quantifies the
amount of work the
object could do as a
result of its motion.
6 different forms of
energy
1. Thermal
2. Chemical
3. Light
4. Potential
5. Sound
6. Nuclear
The connection
between friction and
thermal energy
when you rub your
hands together the
thermal energy is
known as fiction.
Factors that impact the force of
gravity
1. distance
2. Mass
2 examples of energy converting
into another form
When a candle burns the
transformation from a chemical
energy to light and thermal energy
takes place.
Inertia is connected to Newton’s
1st law
inertia is the resistance to
movement
from an outside force and directly
interacts with Newton’s first law in
the fact that the objects inertia is
the force required to change the
motion
The connection between friction and air
resistance
Although air moves around freely, air
will rub against you and cause drag a good
example of this is when the apollo capsule
came into earth's atmosphere and flared
up the red glow was the air friction against
the pod
The Law of Conservation of Energy
energy cannot be created so there is only
a finite amount of energy, energy can be
transferred to another form of energy like
chemical energy to heat energy.
How energy and work are
related
work is the movement of an
object but to do work you need
energy like an electric motor
moves an object but to do this
it uses electrical power.
What makes one thing more energy
efficient than another.
Energy can be lost into other forms of
energy and some things limit the
amount energy transformation like
wires heat up and electrical energy is
lost.
Free body diagrams and how
they help you determine the
net force on an object
The free body diagram
lists the number of forces acting
on an object if you know the
forces on the object you can
determine the net force
How force, mass and
acceleration are related
Force is mass times
acceleration this mean that
you need to accelerate an
object with a certain mass and
the equation is the force
required.
Newton’s Laws
1. an object will stay in its current state of
motion unless an outside force is acted
on it and changes the current motion
2. Force is always equal to the mass of
the object times the acceleration
3. for every force applied to an object the
object will apply an equal counter force
