This is a Lab Stations activity investigating multiple independent variables that might or might not affect the force of kinetic friction as well as the maximum force of static friction. Editable Word Document. Each station investigates one such factor, including: Kinetic Friction:1] Normal Force 2] Sliding Speed 3] Contact Area 4] Type of Surface Static Friction:5] Normal Force 6] Contact Area 7] Type of Surface

This editable PowerPoint presentation introduces Newton's 3rd Law and gives example of action and reaction force pairs. Agent-Object notation is introduced and used to explain the surprising reason why Normal force and Weight are equal and opposite, but NOT an Action-Reaction pair. When you dive off of a cliff, you and the entire earth fall towards each other with equal and opposite forces! (But very unequal accelerations)

In this presentation, a (secretly lazy) horse studies physics at night in the barn and uses Newton's 3rd Law to convince a farmer that it is futile to pull on a wagon since "if I pull on the wagon, the wagon exerts an equal and opposite force on me". Agent-Object notation is explained and used to analyze the three (horizontal) interactions: horse/ground, horse/wagon, & wagon/ground. Ends with an activity for small groups with whiteboards or paper to assess understanding.

This PowerPoint explains “Universal” Gravity means that every object attracts every other object! Even 2 pens, or 2 people, are attracted! Newton's law of Gravity is explained including units and cancellations. Student calculate their attraction to a classmate. Explains the Cavendish experiment (weighing the Earth!) the mass of the entire Earth and the value of "g" near the Earth's surface. A detailed explanation of how to solve proportional reasoning questions involving Universal Gravity

This Editable PowerPoint reviews the 1st and 2nd Laws, and then introduces a taxonomy of Names and Symbols for commonly encountered forces; contact and non-contact. Four real-life examples are used to show how to identify the forces present (and not present!) and create an accurate properly labelled Free Body Diagram. Finally, the Normal force is explained at a micro-physical level, and common confusions dispelled.

This fully editable PowerPoint reviews the Octet rule and the 2 main types of bonding. It introduces covalent bonding, describes with examples how and why atoms share electrons to form compounds. The special tetravalent nature of Carbon bonding is discussed in terms of forming complex 3-D structures essential for life Finally, the naming of covalent compound is introduced, using oxides of nitrogen for examples.

This fully editable PowerPoint defines the Octet rule and the 2 main types of bonding. It introduces Oxidation Number, describes with examples how cations and anions bond and form ionic compounds. Finally, the naming of ionic compound is covered, including with polyatomic ions and transition metals.

This fully editable PowerPoint gives a very clear formal statement of the 2nd Law, and then shows with example how to apply this law to simple situations, including a detailed explanation of how the units involve combine or cancel out.

This fully editable PowerPoint guides students through scenarios that show the relationship between acceleration and net force vectors and "speeding up", "slowing down" or "constant speed" scenarios. These scenarios include elevator example and how cable tension changes (Prep for the Elevator Lab) and also shows the procedure for measuring kinetic friction using a spring scale and a book sliding on a tabletop. (Prep for the Friction Lab)

This PowerPoint provides definitions for power and efficiency in terms of rates for both work and energy transformation. Three example problems guide students through solving problems that involve finding time, power, or energy. Units utilized include Watts, Horsepower, seconds, hours, and Joules.

This fully editable PowerPoint defines Newton 1st Law in 3 ways. It gives rich historic context as to how Galileo demolished the physics of Aristotle, and shows with examples the concepts of Force, Net Force, as well as Static and Dynamic Equilibrium.

This fully editable Powerpoint explains freefall and its relationship to astronauts experiencing weightlessness while in orbit. Finally, Einstein's "happiest thought" and his revolutionary Principle of Equivalence is introduced, the crucial first step in Einstein's formulation of a radical new theory of gravity. Nine links to videos and simulations are embedded for educators who want to open up more depth and wonder!

This well designed and fully editable PowerPoint presentation explains the formula that relates weight, mass, and the acceleration of gravity. Includes 3 fully worked example word problems that show the cancellation and combination of SI units.

This fully editable PowerPoint explains the concept of isotopes in terms of Rutherford's nuclear atom. Students learn to write the names and symbols for isotopes, and how the natural mixture of isotopes determines average atomic mass. The concept of radioactive vs stable isotopes is introduced using a nuclide chart.

This editable PowerPoint has a set of 12 multiple choice and true/false questions that help students to solidify their understanding of when velocity is changing, when objects are accelerating in real-world scenarios, and how the sign and direction of acceleration and velocity vectors determines motion.

This fully editable PowerPoint introduces a detailed statement of the 2nd Law. It also explains the SI units and formulas involved and gives 3 example problems showing in detail how the units combine and cancel out.

This spreadsheet allows you to enter in numeric equalities between units (for example "12 inches = 1 foot") or situational equivalencies (for example 8 slices = 1 pizza) and then generates the front and back of "Conversion Factor Cards" with a conversion factor on one side, and it's reciprocal on the other side. Using a copier in Single --> Double sided mode, a sheet of "Custom Flipable Conversion Factor Cards" is created and can then be cut out for use as student manipulables... Great for

This is a beginning worksheet with lots of scaffolding to get kids started making and using conversion factors and understanding how units cancel out in calculations.

Explains how every equality generate 2 recipricol Conversion Factors that are mathematically equivalent to "1". Gives a simple 3 step process for doing conversion and show a worked example.
