What is Magnetism measured in?
Tesla's
|
What is the difference between Series and Parallel Circuits?
In a series circuit all current goes through all resisters, as for a parallel circuit, current goes through different branches at the same time.
|
What is the difference between Mechanical and Electromagnetic Waves?
Mechanical waves need a medium to transmit energy as to where Electromagnetic Waves do not need a medium transmit energy?
|
What is the difference between Elastic, Inelastic, and Super-Elastic Collisions?
Elastic Collision, kinetic energy stays the same, in an Inelastic Collision kinetic energy is lost, and in an Super-Elastic Collision kinetic energy is gained.
|
What direction do Normal Force and Gravity point?
Normal force always points up as to gravity, it points down.

What does each finger in the first Right Hand Rule represent?
Index Finger - Velocity of Charge (direction of velocity)
Thumb - Direction of Magnetic Field Middle Finger - Indicated the charges that move in a magnetic field |
A series circuit share ______, so they have the same ______. A Parallel circuit shares the _______ and has the same ______.
A series circuit share voltage, so they have the same current. A parallel circuit shares the current and has the same voltage.
|
What are two kinds of Mechanical waves?
Transverse and Longitudinal Waves
|
What is the definition of Impulse?
It adds or takes away momentum from an object by using an outside force and it changes velocity as well.
|
What is Inductance?
Using magnetic fields to push electrons ( electric current).

What equation is used to find the total current of the circuit?
IT = Vt/Req
|
What is the equation for Closed Pipes?
Fn = nV/4L
|
What is the Impulse Theorem?
