Force
Force = mass x ______________
These waves are an example of mechanical waves.
What are sound waves?
A special wheel with teeth.
Energy that is being stored.
What is potential energy?
Electrical energy is the flow of this.
What is electrons?
Change in position due to an applied force (force times distance)
What is work?
This category of waves can travel in a vacuum.
What are electromagnetic waves?
A screw is a modified _______________ (simple machine).
What is an incline plan?
The total kinetic energy that an object's molecules possess (also called heat)
What is Thermal Energy?
Material that resists the flow of electrons
What is a resistor?
The force that resists movement
What is friction?
These are the waves with the highest frequency on the electromagnetic wave spectrum.
What are gamma waves?
The point around which the effort arm rotates on a lever.
Breaking apart of a nucleus into smaller parts (releasing massive amounts of energy)
What is Fission?
The movement of electrons from an area of higher electrical potential to an area of lower electrical potential.
What is current?
In order to use less force you must apply the force over this.
What is longer distance?
What is a wedge?
What is kinetic energy?
A device to control the flow of electrons by opening and closing the circuit.
What is a switch?
This is a force exerted by liquids and gases equal to the mass of displaced fluid
What is buoyancy?
Frequency is measured in cycles per second with a unit called this.
What is hertz?
A wheelbarrow is an example of this class of lever.
What is a second class lever?
This is the amount of energy required to raise one gram of water one degree Celsius.
What is a calorie?
A device that supplies electrons through a chemical reaction.
What is a battery?
