UNIT 1: One Dimensional Motion

This is our Introductory physics unit.  Learn the difference between scalars and vectors.  Next move on to how to pick a constant velocity or accelerated motion equation.  Afterwards this is followed by how to approach a problem when a an object is in the air or it's based on a graph.

UNIT 2: Two Dimensional Motion

Two dimensional motion involves vectors that include motion on the X and Y axis.  The first kind of physics problem, non-projectile, includes object that are turning but not in the air.  Because of this we will use our common SOH CAH TOA trigonometry functions.  Next we get into problems with projectiles that are being accelerated by gravity in the Y axis while having a constant X axis component.  We then teach you how to approach horizontal launch problems mathematically.

UNIT 3: Newton's Laws and Forces

Learn Newton's three laws of motion starting with inertia, then force causes acceleration, and lastly action reaction pairs.  In this section we will look at the difference between mass and weight.  Then look at additional forces like air resistance, friction, tension, spring force and ones created on an incline plane.

UNIT 4: Universal Gravitation and Circular Motion

Learn about Newtons Law of Universal Gravitation.  How all masses in the universe are attracted to all other masses. Then continue on to circular motion and see how centripetal force is necessary to create a circular path.  Inertia would cause an object to continue in a straight line and centripetal force creates the inward arc creating a circle.  Lastly see torque, an equivalent to a rotation acceleration created by a perpendicular force away from a rotational point.

UNIT 5: Work, Power, Mechanical Energy, and Simple Machines

Work and power is the first section of this unit.  See how force must have a component in the direction of motion to do work or have power output.  Mechanical energy is composes of potential and kinetic energy.  See how to solve for either or the amount of one that is converted to another.  Simple machines can't be used to create energy but can be used to multiply a force at the expense of distance.  Learn more about simple machines here.

UNIT 6: Momentum, Impulse, and Conservation of Momentum

Impulse changes momentum, or moving inertia.  This moving inertia remains conserved during collisions.  Momentum is conserved through inelastic and elastic collisions.  A ball thrown and pool balls colliding are example scenarios in this section.

Unit 7: Electrostatics

A charged object has an electrical field around it.  There is an interaction with other charged objects within this field.  We begin this unit by looking at lightning and the difference when charging by conduction, induction, and friction.

  1. Charging by Conduction, Induction, and Friction
  2. What is Lightning?
  3. Coulomb's Law: Calculating the Electrostatic Force
  4. Electrical Fields
  5. Potential Difference (Voltage)
