When an object falls at a constant speed in a fluid, as the forces acting on it are equal |
|
|
Density |
How tightly packed the particles in an object are |
|
|
A moment |
....the force multiplied by the perpendicular distance to the force from the turning point |
|
|
Principle of Moments |
When an object is in equilibrium the sum of the anti-clockwise moments must be equal to the sum of clockwise moments |
|
|
Fluid |
A matter where the particles are free to flow past each other |
