|
F=ma |
Force (N) = mass (kg) × acceleration (m/s^2) Newton's Second Law (abbreviated) |
|
|
Define: Inertia |
The ability of an object to resist a change in motion. An objects natural state of motion is stationary or moving in a straight line at a steady speed. An unbalanced external force is needed to change this state. |
|
|
Define: The Newton |
The force that gives one kilogram an acceleration of one meter per second squared. 1N = 1Kgms^-2 |
|
|
Define: Moment Unit? |
Moment = Force × Perpendicular Distance From Pivot Q { × Sin(⊙) } Unit: Nm |
|
|
Define: Equilibrium |
Clockwise Moments = Anticlockwise Moments therefore no resultant turning moment. No resultant force. |
|
|
Define: Terminal Velocity |
When a body travels at constant velocity while falling through a fluid. Drag (+upthrust) is equal to the weight of the falling object |
|
|
Define: Pressure |
Pressure = Force/Area = Force Acting on a Unit Area Unit (normally) = N/m^2 = Pascals "Pa" |
|
|
Define: Density |
Density = Mass/Volume |
