Fnet = m•a

The F_net = m•a Concept Builder targets the concept of net force and its relationship to mass and acceleration. Learners are presented with a physical situation involving a known mass and acceleration and must decide on at least two horizontal and/or vertical forces that must be added to the object in order to produce the specified acceleration. The Concept Builder includes three difficulty levels with three Question Groups at each difficulty level. The first difficulty level includes three situations involving either a horizontal or a vertical net force on a 1-kg mass. The second difficulty level includes three situations involving either a horizontal or a vertical net force on a 2-kg, 3-kg, or 4-kg mass. The third difficulty level includes three situations involving both a horizontal and a vertical net force on a 2-kg, 3-kg, or 4-kg mass. Question-specific help is provided for each of the nine situations. The built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
