Circular Motion and Universal Gravitation
Gravity is a force so it is measured in this unit.
What are Newtons?
These are the two types of charges.
What are positive and negative?
This term means the flow of charge.
What is current?
In order for magnetic fields to exist, electric charges must be doing this.
What is moving?
Frequency and this quantity have an inverse relationship.
What is period?
If you are not having fun on a seesaw it is probably because you have a balance what.
What is torque?
Metals are conductors. Rubber is this kind of material.
What is an insulator?
The relationship between voltage, current, and resistance is named after this scientist.
Who is Ohm?
We use this set of rules to determine the relationship between a moving charge, magnetic fields, and magnetic forces.
What are the Right-Hand Rules?
What is temperature?
We use this letter to represent the Universal Gravitational Constant.
What is (Big) G?
The law that describes the interaction between two charged particles is named after this scientist.
Who is Coulomb?
Nikola Tesla proposed this type of electric current.
What is alternating current (AC)?
An electric motor is identical to this device in every way, except that a motor converts electric energy to mechanical energy, and this device does the opposite.
What is a generator?
As the speed of sound increases but frequency stays the same, this quantity also increases.
What is wavelength?
Both gravity keeping planets in orbit and the washing machine basin keeping your clothes in a circular path are examples of this type of force.
What is centripetal?
Water is an example of this, which is why a stream of water will bend around a charged rod.
What is an electric dipole?
If you have a string of light bulbs and remove one but the rest stay on, the string is wired this way.
What is parallel?
Clusters of atoms that are magnetically aligned are called magnetic these?
What are domains?
The Tacoma Narrows Bridge disaster is an example of this wave phenomenon.
What is resonance?
A moving bicycle remains upright because of this phenomenon.
What is angular momentum?
A metal conductor, sometimes called a Faraday cage, protects its contents from electric fields in a process called this.
What is electric shielding?
This is a component found in many electrical devices. It contains a very thin filament that breaks when there is too much current in the device, but it saves the device from being damaged.
What is a fuse?
If a transformer has a turns-ratio of 1:50 and the primary coil has 500 V impressed across it, this much voltage is across the secondary coil.
What is 25,000 V?
A total shadow is called this, whereas a partial shadow is called this, instead. (You need both answers to earn the points).
What are the umbra and penumbra?
