This lesson explores the concepts of mass, force, and velocity. Students will conduct investigations to understand how different masses affect velocity when the same force is applied. The lesson includes hands-on experiments with objects of varying mass and a simulation to observe changes in velocity. The difference between mass and weight is explained, emphasizing that mass remains constant regardless of location, while weight varies with gravitational pull.
