Opis

This book contains graphs showing an electric train moving on flat and inclined tracks. Graphs show data of Watts, including usage at minimum and maximum velocity and variations due to number of cars and length of track. Additional analyses examine the magnetic field and voltage of the electric track, comparing it to other phenomena. Basic analyses of movement, velocity, and acceleration are also included, based on video analysis techniques. These graphs can be used for lesson plans by teachers and parents.
