Why do things move in certain ways? And how can you make them move faster or slower? These are questions that engineers wonder about when they design cars and spaceships and roller coasters. The key to understanding them lies in three laws of motion discovered over 300 years ago.
In this unit, you will learn about different types of forces and how they cause objects to move in certain ways. You'll also learn about how different machines make use of forces and motion to help people get work done.
The Age 11-13 semester 2 science units require materials from the Semester 2 Science Kit.
