Describe the interaction of objects at a distance through gravitational, electrostatic, and magnetic fields, and through direct contact involving normal contact force and friction.
Understand that object interactions produce force pairs that can be mathematically represented as vectors.
Analyze the fundamental differences between vector and scalar quantities through specific examples.
Construct and analyze vector diagrams to visually resolve forces, determine net forces, and identify equilibrium states using scale drawings.
Construct and interpret free body force diagrams to model physical scenarios.
Evaluate the collective forces acting on an isolated solid object or system, determining the resultant force or recognizing the special case of balanced forces resulting in zero net force.
Explain the practical application of lubrication in reducing unwanted energy transfers within mechanical systems.
