Topic hierarchy

4.1: Introduction
There are three laws of motion that describe the relationship between forces, mass, and acceleration.
4.2: Force and Mass
Force is any influence that causes an object to change, either concerning its movement, direction, or geometrical construction.
4.3: Newton’s Laws
Newton’s first law of motion describes inertia. According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force.
4.4: Other Examples of Forces
Weight is taken as the force on an object due to gravity, and is different than the mass of an object.
4.5: Problem-Solving
Basic problem-solving techniques can aid in the solution of problems involving motion (i.e., the laws of motion).
4.6: Vector Nature of Forces
Forces act in a particular direction and have sizes dependent upon how strong the push or pull is.
4.7: Further Applications of Newton’s Laws
Net force affects the motion, postion and/or shape of objects (some important and commonly used forces are friction, drag and deformation).
