The transient response of a wave front that forms a transverse cusp caustic is studied. The travel time surface of a simple cuspoid caustic is known to have the general shape of the singular surface of the next higher order cuspoid catastrophe. Though the transverse cusp wave front considered here is curved in two dimensions, it is also shown to have a ...

Students observe the relationship between the angle of a catapult (a force measurement) and the flight of a cotton ball. They learn how Newton's second law of motion works by seeing directly that F = ma. When they pull the metal "arm" back further, thus applying a greater force to the cotton ball, it causes the cotton ball to travel faster and farther. ...
