Simple machines
Simple Machines introduces Class 9 Science students to how basic devices make work easier by changing the size or direction of a force. Within the chapter Work, Energy, and Simple Machines, students explore levers, pulleys, inclined planes, wheels and axles, and screws. They learn to identify effort and load, understand mechanical advantage, relate machines to work and energy, and apply these ideas to familiar tools and everyday situations.
