Gravity keeps the moon where it's supposed to be — in orbit. Peepo / Getty Images Gravity is a force that we experience every day, yet it remains somewhat of a mystery. It's the reason we stay grounded on Earth and why objects fall when dropped. Although there are several theories ...
g is the acceleration of gravity h is the height of the fluid above the object The pressure due to the liquid alone (i.e. the gauge pressure) at a given depth depends only upon the density of the liquid, the acceleration of gravity and the distance below the surface of the liquid. Th...
this acceleration is called acceleration due to gravity; for objects near particular large bodies like planets this acceleration is approximately constant, meaning all objects fall with the same acceleration.
Understand what the equation for power is. Learn how to find power in physics using the power formulas. Practice the examples of calculating power in physics. Related to this Question What are the units of energy? What are units of frequency?
What's the definition and equation of the mechanical efficiency of the machine? Energy is fundamentally grouped into two kinds. a) What are they and define them. What is the definition of gravity? What is conservation of energy? What is Perpetual Motion?
Corollary: another thing which can be concluded from the above equation is that if the mass is neither removed nor added but only moved from one position to other on the parent body, the new center of gravity is given by the same equation except that M remains unchanged, therefore Pla...
This equation gives the magnitude of the force, and since it is an attractive force, it will always be directed towards the other object. From the above equation, we can come to the conclusion that anything that has mass has gravity. Objects with heavier mass have more gravity. The closer...
General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has to obey an equation, called the Einstein equation, which explains how the matter curves the spacetime. ...
Gravity can be described in a variety of ways. Here's how Newton and Einstein took gravity from an observation to a measurable phenomenon.
An extended body is a nonspherical object used in Newton's Law of Universal Gravitation. Using the gravitational attraction equation and an example, learn how to solve for the gravitational attraction of extended bodies. Related to this Question ...
