Investigate, measure, and calculate position, displacement, velocity and acceleration. 1.1	Describing Motion with Velocity vs Time Graphs - first of five lessons from The Physics Classroom Kinematics Equations and Graphs (use of velocity-time graphs to describe the motion of objects) Six practice problems are provided, each requires the student to construct a velocity-time graph. Answers, including graphs, are provided. Moving Man Simulation- Learn about position, velocity, and acceleration graphs. Move the little man back and forth with the mouse and plot his motion. Set the position, velocity, or acceleration and let the simulation move the man for you.
Analyze vector diagrams. 1.2	An index of animation of vectors and projectiles from the Physics Classroom Component Forces Simulator - choose force vectors, change magnitude, determine resultant Resultant Vector - explore the effects of combining different vector quantities Resultant of Forces - This applet deals with forces exerted on a body.You can vary the number of single forces by using the choice box at the ride side. It is possible to change the sizes and directions of these forces by dragging the arrowheads to the intended positions with pressed mouse button. Resolution of a Force into Components - java applet Vector Addition - Vector addition with moveable vectors and with spread sheet computations [excel workbook to download] Vector Analysis Worksheets - Vectors: Motion and Forces in Two Dimensions - an index of lessons on vectors, projectile motion, and forces in two dimensions Vector Direction - practice with the use of scaled vector diagrams for the representation of the magnitude and direction of a vector.

You must decide on a number of factors; the height of hill #1, hill #2, the size of the loop, the initial speed of the coaster, its mass, the gravity at work and the amount of friction on the track Model of a Carousel (Centripetal Force) - The simulation assumes a circular motion with constant angular velocity. Circular Motion and Centripetal Force - an interactive java applet

You get a maximum of 4 shots to hit the target with a cannon ball Design and Test - This project simulates the Design and Test process through the development of a virtual paintball catapult. The student must build catapults capable of performing a variety of tasks, stay within the allotted budget, and interpret test results to fine tune their design.

What will happen if both cannons fire at the same time? Projectile motion applet displaying horizontal and vertical vectors
Distinguish between mass and weight using SI units. 1.7	Your Weight on Other Worlds - This Exploratorium site gets your students' attention by showing that their weight will vary with different gravitational attraction (you will not believe what you would weigh on a Neutron star!). Then, a very good presentation of the difference between weight and mass is given. A weight and mass converter is provided by ConvertMe.com. After your students use this converter, perhaps you could discuss if it is appropriate to perform this type of conversion.
