Examples of Force Lesson SummaryShow Frequently Asked Questions What is an example of a force in physics? The most common examples of forces are gravitational and normal forces. Gravitational force is a non-contact force and is an attractive force between two objects with mass. For example, ...
How do you calculate power in physics? Power can be calculated in two main ways. The first is to divide the work done by the time it took. The second is to multiply the force by the velocity. What is the formula for power in watts? The formula for power in watts is given by the...
In this paper, it is made a proposal for two new ones: the kind of the Hubble field as well as a De Sitter-Hubble equation. Moreover, it is proposed a necessary change in the equation of force in Special Relativity. It is included a paragraph on the search for Symmetry in Physics, ...
Bernoulli’s equation in that case is P1 + ρgh1 = P2 + ρgh2. We can further simplify the equation by taking h2 = 0 (we can always choose some height to be zero, just as we often have done for other situations involving the gravitational force, and take all other heights to be ...

From the concept of the lines of force used in defining the fields and explained earlier, we can understand that the surface integrals of the field, say ∫Sv E∙ dS, gives the total number of the lines of forces coming out of a volume V enclosed by the surface Sv. Therefore, it rep...

Torque requires a combination of distance and the force applied. This is also applied when using levers, a long lever can rotate heavier loads easier than a short lever. In an engine torque is the capacity for the engine to do work.
