The goal of the Motion and Forces virtual lab is to allow students to investigate how forces impact the motion of a wooden sled. Students conduct experiments to understand the relationship between height, mass, friction, and gravity.
Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
