Experiment: Car 1 will roll down the ramp and exert a force on car 2. The force experienced by car 2 is measured indirectly using (the distance it travels? or its speed?)
. If the force increases, car 2 will travel (?slower ? Farther?)
. The independent variable, or what’s being manipulated in the experiment, is (? the starting height of car 1 or The type of bumper attached to car ?)
. The dependent variable, or what’s responding, is (?The distance car 2 travels or the speed of car 1?)
. The height and starting position on the ramp are constants in this experiment.

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
