1. A force is needed
2. The point of application of the force is to be displaced.
3. If the displacement is in the direction of the force then work is said to be done by the force and if the direction of displacement is opposite to the force then work is done against the force.

2.) The object must move in the direction of the force (the exerted force in 1.)

What conditions must be met in order for a court to order a forced sale of jointly owned property?
C. The applied force must make the object move. D. At least part of the applied force must be in the same direction as the movement of the object.
Explain when a matter is in a state of equilibrium?
It is in equilibrium when the two conditions are satisfied - there is no net translational equilibrium and no net rotational equilibrium. For translational equilibrium, the summation of forces acting on the matter must equate to zero, which means that there is no resultant force. For rotational equilibrium, the sum of moments must be zero, which means there is no resultant torque. When these two conditions are met, the object will be stationary, i.e. it is in a state of equilibrium.
What is acceleration of a Car that is going at a steady speed of 50 mph?
Zero. Acceleration = change in velocity/change in time As you see the conditions are not met for acceleration to be taking place.
How pressure changes as the velocity of a fluid increases?
If we assume that the fluid we are referring to is that of an ideal fluid (incompressible and non-viscous) and is undergoing a laminar flow, we can model this problem by Bernoulli's principle and equation. Bernoulli's principle states that if the above conditions are met, the energy density of a fluid must be a constant, fixed value. This means that if the velocity of a fluid increases, other factors must decrease for the energy density of a fluid must be conserved. Bernoulli's Equation is the sum of the magnitude of the pressure, kinetic energy and potential energy of a fluid is equal to a constant. Therefore, if a velocity of a fluid increases, the kinetic energy of the fluid increases. As a result, the pressure or the potential energy must decrease. Both or only one may change; the result is dependent on the situation.
What is filtered vibration?
The filtered vibration (at rated voltage and frequency) at both twice the speed (2n) and twice the frequency (2f) must not exceed 0.05 in/s peak velocity. These are two independent measurements at different frequencies. The limit must be met at both frequencies when measured in any axis on the bearing housing.
What conditions must be met in order for work to be done?
