1. As the tape moves across the coil, the coil of wire experiences a changing magnetic field. This
changing magnetic field induces a current in the coil, which can be read out as an electrical
signal. A practical applicati

What Its About
Any problem about a moving object in which you do not need to know what is causing the
motion is called a kinematics problem. This worksheet is about the basic quan

What Its About
Using proportionalities. Two quantities, x and y are said to be proportional if they obey the
equation y = cx where c is a constant. (In this worksheet, well always

What Its About
The basics of geometry. When an object follows a curved path, its position, velocity, and
acceleration can now have infinitely many different directions! It no longer suffices to just
give a positive or negative
Preparation for Worksheet 3
What Its About
Having two equations and two unknowns. As you probably remember, the basic idea is
to solve (algebraically) for one of the unknowns and then substitute that into the other
equation. This leaves you with an equati

What Its About
Using proportionalities again. Not all quantities are linearly proportional; nature likes many
different power law relationships. For example, the amount of energy that an object
