Forces In Motion

"Introduces the connection between force and motion and describes the effects of air resistance, mass, and gravity"--Provided by publisher.

Forces can't be seen, but without them, nothing around us would happen! A force is a push or pull that usually causes movement. Friction is a force that opposes motion and slows things down or stops them. Famous scientist and mathematician Sir Isaac Newton wrote the rules about forces and motion.

Everything moves! Kids run around the playground, cars drive on the road, and balls fly through the air. What causes all this motion? Physics! Forces and motion rule the way everything moves through space. In Explore Forces and Motion! With 25 Great Projects, readers ages 7 through 10 discover that the push and pull of every object on the planet and in space depends on how a force acts upon it. Things float because of a force called buoyancy, we stick to the ground because of a force called gravity, and we make footprints in sand because of a force called pressure. Physics becomes accessible and interactive through activities such as a experimenting with a water cup drop, building a bridge, and spotting magnetic field lines. Simple machines such as levers, pulleys, and wedges are used as vehicles for discovery and comprehension of the foundational concepts of physical science. Using a theme familiar to everyone—motion—this book captures the imagination and encourages young readers to push, pull, twist, turn, and spin their way to learning about forces and motion.

Forces and motion are at work all around you—when you kick a ball, ride a bike, or drop a book. But what exactly are forces? And how do they make things move? For thousands of years, scientists have been testing hypotheses about forces and motion and learning from the results of their experiments. These lead to more questions: Why do you speed up when you're biking down a hill? Why are heavier objects harder to pull? Why doesn't the moon float off into space? The answers may surprise you! Find out how forces and motion are at play with everything on Earth and beyond.

Learning about heavy physics concepts can sure weigh down your brain! You need to understand huge forces (like gravity, magnetism, and inertia), huge speeds (light moves at 670,615,200 miles per hour), and even huger mysteries (what space-time is)--Cover.

Explore The Relationship Between The Strength Of A Force And Its Effect On An Object As Well As The Effects Of Forces In Nature.

This series provides an information library on the main aspects of physical science, with an emphasis on enquiry; answering the questions that children ask, addressing the topics that they are required to research at this level, and using familiar examples.

A simple look at motion.
