dynamics

Examines the forces involved in a bicycle's braking, a pitcher's curveball, and an airplane's liftoff, discussing several concepts including acceleration, friction, terminal velocity, and balanced and unbalanced forces.

An introduction to kinetic energy describing the basics of mechanical energy.

An introduction to the three laws of motion that explain how forces act on matter and on how matter responds to forces.

Forces--those that push and pull on objects--are a critical concept in the elementary science classroom. For learners to truly understand this physics topic, they need to see forces in action. This well-designed book takes an up-close look at forces, exploring essential themes such as gravity, magnetism, and friction, through at-level and engaging text that leads into a related high-interest activity, such as making balloon rockets and hovercrafts as well as testing whether objects sink or float. Colorful images accompany both the main information and the step-by-step instructions.

While playing in her tree house, Jesse is intrigued by a falling sycamore seed that slowly spins to the ground. But when she sees acorns falling fast directly down to the ground, she must solve the riddle while learning about propellers and windmills and using technology to understand aerodynamics.

"Curious Pearl and her friends love soccer. There's plenty of fun, and lots of forces and motion in action. Pearl teaches her friends all about physical science as they play a game on the soccer field"--Provided by publisher.

This book follows the search for an understanding of what energy is, from the Greek philosophers to the scientific discoveries of the early 21st century.

Introduces the concept of moving objects in different ways, including pushing and pulling.

Explores the various forms of energy used at an amusement park, including heat, potential and kinetic energy, electricity, and more.

Brief text and photographs describe how to move objects by exerting a force which is a push or a pull.
