In this well-illustrated activity, learners examine the three types of intermolecular forces: dipole-dipole forces, London or Van der Waals forces, and the hydrogen bond. Two interactive questions are included.
Dr. Miriam Douglass
Dr. Martin McClinton
In this learning activity you'll explore a step-by-step process to solve simple free-body diagrams. They identify forces acting in the x or y direction in interactive exercises.
Learners use trigonometry to calculate angular input forces involving Class 2 mechanical levers.
