Forces And Motion On Earth

Readers learn about the forces of friction, magnetism, and gravity as well as the concept of balanced and unbalanced forces on Earth.

This title introduces the reader to the ways in which forces are used in our everyday lives. Find out how forces make things move and change direction, learn about the effects of gravity, and discover how our knowledge of forces has led to the tools that we use today. This series is packed with the latest scientific information and is an ideal support for physics students at Key Stage 3 level. The series will also be of interest to older students. Fascinating feature boxes outline recent physics research and encourage the reader to look more closely at the world in which they live. Key concepts are brought to life with full colour illustrations and mini quizzes help to reinforce new ideas.

Describes different types of forces and offers experiments to demonstrate the priciples of physical science that apply.

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.

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

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.
