Inversely | When two values change in opposite directions, so that if one increases the othe decreases. |
Newton's second Law | The acceleration produced by a net force on a body is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the body. |
Fluid | Anything that flows; in particular, anyh liquid or gas. |
Air Resistance | friction or drag, that acts on something moving through air. |
Free-body Diagram | A diagram showing all the forces acting on an object. |
Pressure | Force per unit of surface area where the force is perpendicular to the surfaces of a lens. |
Pascal | The SI unit of pressure. One pascal (Pa) of pressure exerts a normal force of one newton per square meter. |
Terminal Speed | The speed at which the acceleration of a falling object is zero because friction balances the weight. |
Terminal Velocity | Terminal speed together with the direction of motion. |
