Reprint edition published in October 2024. "Physics affects our daily lives. Its principles are at work when we ride a bicycle, wear a pair of glasses, play a computer game, operate a vacuum cleaner, play a music CD or call a friend on the telephone. Physics is at work all around us all the time. This book explores projects in the field of physics. For each project you’re given a material list, hypotheses, procedure, and suggestions for different ideas to try. Experiments are fun, and sharing what you’ve learned with others is even better! "
