|
Inertia
|
The property of things to resist changes in motion. |
|
|
Normal Force
|
Component of support force perpendicular to a supporting surface. For an object resting on a horizontal surface it is the upward force that balances the weight of the object.
|
|
|
Support Force
|
Upward force that balances the weight of an object on a surface. |
|
|
Normal
|
At right angles to, or perpendicular to a normal force acts at right angles to the surface on which it acts. in optics, a normal defines the line perpendicular to a surface about which angles of light rays are measured. |
|
|
Net Force |
Combination of all the forces that act on an object.
|
|
|
Equilibrium Rule
|
On an object or system of objects in mechanical equilibrium, the sum of forces equals zero. ∑F=0
|
|
|
Force
|
Any influence that tends to accelerate an object; a push or pull; measured in Newtons. Force is a Vector Quantity.
|
|
|
Newton
|
Scientific Unit of force. One Newton is the force applied to a 1-kilogram mass that will produce an acceleration of one meter per second per second. 1 lb = 4.448 Newtons
|
|
|
Mechanical Equilibrium
|
State of an object or system of objects for which any impressed forces cancel to zero and no acceleration occurs and when no net torque exists. ∑F=0
If at rest the state of rest persists. If moving, motion continues without change. |
|
|
Kilometer (km)
|
1000 Meters |
|
|
Newton's Laws of Motion: |
Law 1 the Law of Inertia-Every object continues in a state of rest or of uniform speed in a straight line, unless acted on by a nonzero net force.
|
|
|
Newton's Laws of Motion: |
The acceleration produced by a net force on an object 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 object.
|
|
|
Newton's Laws of Motion: |
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the two objects.
|
|
|
Scale
|
In Music, a scale is a succession of notes of frequencies that are in simple ratios to one another

|
|
Equilibrium Rule
|
For any object or system of objects in equilibrium, the sum of the forces acting equals zero. ∑F=0
