Sir Isaac Newton formulated the laws of universal gravitation and the three laws of motion. These explain how forces act on matter, and on how matter responds to forces. This leads to an understanding of how things move.
"A scientist named Sir Isaac Newton wondered why things fall to the ground. He knew that forces made objects fall and move. Newton described three Laws of Motion to explain what happens when objects move"--Provided by publisher.
"Explore this fascinating timeline history of physical science! What are matter, motion, gravity, electricity, magnetism, and substances? Who first studied these concepts? And who later built on and expanded the work of those early thinkers?"--.
"Explains how a force, such as a push or a pull, can put an object in motion. Simple activities show how a force can move an object that is not moving or stop one that is"--Provided by publisher.
From using a can opener to riding a bicycle, all daily activities involve force and motion to some degree. Friction, magnetism, gravity, and more are all addressed in this look into physical science. Infographics and illustrations help to clarify the abstract concepts..
"Motion is a change in an object's position. This title explains in a clear, simple way how objects are moved by a change in energy. Simple activities show young readers how energy is changed by applying a force, either by coming in contact with an object or by a force that does not touch it physically, like gravity"--Provided by publisher.
