Ideas

This is a list of some possible project ideas:

Kinematics

• show that the acceleration vector is always pointed down. Have a ball shoot up, reach the highest point, then fall. Have the velocity and acceleration vectors shown during the motion.

• do the same thing but with a horizontal component

• show a bouncing ball with x,v,a plots simultaneously

• Have a particle move around the screen randomly, and show vel and accel vectors during the motion

Forces

• Have a ramp that changes the steepness with a slider. A box on the ramp shows the changing force vectors. Maybe include friction to show when the box starts to slide.

Momentum

• Center of mass moves in a parabola, even for spinning objects:

Rotations

• animate this:

• animate this:

Oscillations:

• do something with the Reference Circle

• pendulum: Show the accel and velocity vectors: Like this, but with a slider to control L (or g or f)

• Use the arrow object to make this a sim: link to video - waves

• Show the two main types of waves: tranverse-longitudinal-waves0001-0090.mp4.mp4

• Doppler: doppler effect viz

Optics

• turn this drawing that shows how wave fronts refract into a sim:

• do something like this: but not in 3d (or maybe in 3d) http://surendranath.tripod.com/GPA/Optics/WideDoubleSlit/WideDoubleSlit.html

Math

• graphically show what slope is (rise over run)

• graphically show how Delta x needs to be small in order to get information at a given moment, not an average.

• show visually how the average is equal to (min + max) / 2

• Show what it means to have a envelope around another curve: y = e^-t/τ * sin(t) Like this: decay Change the tau to change the decay rate.

Plots

• Draw your guess for the graph of a function
