In this homework, use the Simple Object example to simulate the Newtonian mechanics of a particle moving under gravity:

Position P

Velocity V = dP/dt

Acceleration A = dV/dt = gravitational acceleration of 9.8 meters/sec^2 in the downward (negative z) direction

It will probably be helpful to review the Integrating Differential Equations lecture note.

You may assume all the mechanics are happening in the z direction, and ignore x and y.

When your particle reaches the floor, P.z<=0, make it bounce by flipping the sign of the velocity.

681 students: make your simulation conserve energy, including when it bounces off the floor, for example by using Leapfrog or Verlet time integration.

To save your PixAnvil simulation, hit the "Save" tab, select all the text, and save it to a .html file using a plain text editor such as Notepad. Turn in your updated .html simulation on Blackboard (you'll need to log in first) by the due date of Wednesday, January 21.
