Gravity is the force that keeps us grounded. 1 Load The demand for services or performance made on a machine or system. 1 Force Strength or energy as an attribute of physical action. He used all his force to open the stuck window. 1 Load A burden or heavy pressure. He felt the load...
experience the same acceleration toward the center of the field acting on their masses. Thus, the only factor that changes the force of gravity felt by different objects on the same planet is their mass: The more mass, the larger the force of gravity and vice versa. ...
I am stuck on how my teacher got to the last equation in #4. Problem Statement: A 2,000 kg rocket carrying 3000 kg of fuel is drifting in space when it...
What's the definition and equation of the power generated by a machine or an engine? Define electric potential. What is definition of electric current? What is the definition of electric current? What is the unit for power, P? Explain how to estimate the wattage capacity needed by a power...
What exactly presents the Einstein equation for gravity? What would happen if the force of gravity were to disappear suddenly? Who invented gravity? Define the term center of gravity. Who invented gravity force? Why is gravitational energy negative?
Well we simply imagine that if the whole mass of the body were to be concentrated at a single point where would that point be? That imaginary point is known as the center of mass of the body. We also know that whether any other force acts on a body or not, the force of grav...
The force (F) acting on the object is demonstrated in Newton's second law, which states: F=ma In this case, the acceleration is due to gravity, so a = g, which means that: F=mg which is the equation for weight. ...
It basically set forth the idea that gravity is a predictable force that acts on all matter in the universe, and is a function of both mass and distance. The theory states that each particle of matter attracts every other particle (for instance, the particles of "Earth" and the particles ...
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. ...
Newton's Second Law can be written in equation form: F = ma. For falling objects we can write F=mg where g is the acceleration due to gravity. The force of gravity is what causes free falling objects to accelerate. These objects all accelerate at the same rate of 9.8 meters/sec^2 ...
