Force & Work
Metric unit used to measure work
What is joule?
A machine is any device that transmits or modifies this
What is force?
The two main types of energy
What are kinetic and potential?
The sum of kinetic energy and all forms of potential energy associated with an object
What is mechanical energy?
Heat is the transfer of energy between objects at different this
What is temperature?
A force can be defined as any this or pull
What is a Push?
It is how much a machine increases your force output
What is Mechanical Advantage?
The type of energy that depends on mass and position
What is potential energy?
A pendulum encounters this resistance each swing. It slows it down until it stops
What is friction?
Thermal conductor are substances that this transfer energy as heat
What is rapidly?
In order for something to take off and leave the floor it must overcome this force on earth
What is gravitational force?
All the classes of levers contain these items
What is a Fulcrum, Force, and Load?
Type of energy that comes from atoms, it's used in power plants to generate electricity
What is nuclear energy?
Conservation of Energy states that energy is not created nor this
What is destroyed?
A classic example of this is water filled with ice
What is thermal equilibrium?
This can be described and measured by speed, velocity, and acceleration
What is motion?
To find the Mechanical Advantage of this simple machine, you divide its length by its height
What is inclined plane?
Thunder created by a strike of lighting is an example of this type of energy
What is Sound Energy?
The Potential energy of an object that has a height of 10 m and a mass of 1kg
What is 98 Joules?
An example of this is wood, which feels warmer than metals at room temperature
What is a thermal insulator?
This formula can be used to calculate force
What is mass times acceleration?
The Mechanical Advantage of this Simple Machine is the number of rope sections holding a load
What is a pulley?
A type of energy produced when our bodies shiver
What is thermal energy?
All the energy like nuclear, chemical, internal and electrical, that is not related to an object’s motion or position
What is nonmechanical energy?
A substance is required the change of temperature from this to this
What is 1kg by 1c
