KEY CONNECTIONS
Formulas
P = m(g ± a)
P = N
Note: The sign depends on the direction of acceleration; P = N for a body on a support without vertical acceleration.
NOTATION
Quantities in formulas
- Weight is the force with which the body acts on a support or suspension.
- Mass is a scalar physical quantity that is a measure of the inertia of a body.
- Gravity acceleration is the acceleration of a body under the influence of gravity without taking into account the resistance of the medium.
- Acceleration is the rate of change in the speed of a body.
- The support reaction force (normal pressure force) is the force with which the support acts on the body perpendicular to the surface.
