**Part One:**

This is your first virtual lesson. In this lesson, you will revisit your knowledge of Newton’s Laws of Motion and test your knowledge regarding general information about these Laws.

**Let’s get started!** This first link below is an interactive page that explains Newton’s Laws of Motion using animations of a worm and an apple, by using the same setup for each law and has the student interact at each part, the information on Newton’s Laws of Motion is more likely to stick.

The second link gives short and simple examples of all three of Newton’s Laws of Motion along with quiz questions and answers. The explanations of all three Laws of Motion have simple and straightforward animations.

**Part Two:**

Click on the link below to access the Java Applet that shows an example of Newton’s Second Law of Motion by showing the gravitational acceleration. In this applet, you will be able to control the values to the mass of the wagon, mass of the hanging object and the coefficient of friction in an air-track system. You will learn:

- The effect of the coefficient of friction on the acceleration of the wagon mass.
- The acceleration effects (that is, the wagon moves faster with time) of the wagon under varying amounts of mass from the hanging object.
- Calculate the acceleration and time at a specific time.
- The underlying formulas, as an application of Newton’s Second Law, of the system displayed in the outlet.
- The parabolic behavior of acceleration under constant acceleration and initial speed of zero.

**Part Three:**

- By exploring the links on this page, you will learn:
- The effect that increasing damping has on Newton’s Cradle.
- The effect of gravity and elasticity on the swinging spheres.
- The energies and the forces at work on the system at all times.
- The function behavior of a variety of variable combinations; for example, the parabolic behavior of the y vs x in the typical Newton’s Cradle behavior.
- The equations that govern the conservation of momentum as it associates with Newton’s Cradle.

The first link is a Java Applet that shows Newton’s Cradle, an example of conservation of momentum.

The second link shows the same thing, but is a YouTube video.

The third link provides an analysis of the mathematical equations that express Newton’s cradle, the Laws of Conservation of Momentum and Energy. You will be able to see the effect of conservation of momentum and energy from different perspective.

**Part Four:**

By exploring the links below , you will learn:

- The equations that rule over a freely falling object.
- What the effect of free falling objects of different sizes would have on the human body.
- The behavior of a free falling ball under different initial conditions.

The first link is to a YouTube video showing the power of gravitational acceleration by making even the most harmless fish dangerous when falling from great heights.

The second link is a YouTube video of an episode of Myth Busters and the myth that throwing a penny from a skyscraper could kill a person.

The third link shows the mathematical formulation of a free fall acceleration system. It shows graphs and equations related to the movement of the freefalling object.

The fourth link is to a Java Applet that shows free fall acceleration of a ball. The student can change the initial position and velocity and acceleration of the free falling ball. The goal of these links is to show the student the effect of free-fall acceleration.
