The PhET: Forces and Motion Basics Activity Guide is used along with the free *Next Generation PhET Simulation “Forces and Motion Basics”. Students will discover how balanced and unbalanced forces affect an object’s motion and then explore the relationship between force, mass, acceleration, speed, and friction on the motion of objects. The activity guide takes students through the 4 parts of the simulation: Net Force, Motion, Friction and Acceleration. Students are encouraged to make predictions
