Units
Current is measured in this unit.
What is an ampere (or amp)?
This constant describes the acceleration of an object in freefall.
What is acceleration due to gravity (g = 9.81 m/s2)?
This law describes the motion of an object remaining the same unless acted upon by an unbalanced force.
What is Newton's 1st Law of Motion?
This is the energy of an object in motion.
What is kinetic energy (or mechanical energy)?
The magnetic field around a bar magnet is always strongest at these points.
What are the poles (N and S)?
This unit is used to measure frequency of a wave.
What are Hertz (or 1/s)?
A feather and a bowling ball are dropped from the same height in a vacuum. This one reaches the bottom of the vacuum first.
What are the feather and bowling ball (or neither)?
This law describes the equal and opposite forces acting between two objects that are in contact with each other.
What is Newton's 3rd Law of Motion?
Describe the energy transformation that takes place in a generator.
What is mechanical energy to electrical energy?
This movement of charge is when a charged object is used to separate the positive and negative charges in an object.
What is polarization?
Its unit is Watt
What is power?
