According to Newton's first law, the Earth would continue to move in the same direction with the same magnitude it had the moment gravity stopped. Note that the direction is perpendicular to the radius drawn at that point tangent to the curve. The diagram illustrates an intuitive and accurate...

There are two primary units that tell you how dense a fluid is: Specific Gravity and API Gravity.
However, this result failed in recent infrared (IR) modified Hořava–Lifshitz (HL) gravity. The difficulty stems from the fact that HL gravity is Lorentz-violating. Motivated by this problem, we use the Misner–Sharp mass to investigate the thermodynamics near the apparent horizon in HL ...
That means that the force of gravity must be proportional to the mass of a body. This force of gravity is called weight W and W=mg. The kinematics equations that describe an object in free fall, then, are simply v=v0−gtx=x0+v0t−12gt2, where the acceleration a has just been...
.The Reynolds number indicates the ratio of viscous to inertial forces and reflects the tendency towards turbulence, whilst the Galileo number indicates the ratio of viscous to gravity forces. The Ergun equation is valid for the range of particle Reynolds numbers, Re, from 0.1 to 1000. It gives...
Eloss= energy loss per unit mass in flow (J/kg, Btu/slug) 1 psi = 144 psf Head Form (1)can be modified by dividing with gravity like h = p1/ γ + v12/ (2 g) + h1= p2/ γ + v22/ (2 g) + h2- Eloss/ g = constant (2) ...
Center of gravity of an object is the point at which the mass or weight of the object is assumed to be concentrated. What is an example of the center of gravity? The best examples for the center of gravity of an object is the seesaw in a children's park and the weighing balance. Ho...
The graph displays the combinations of W/S and T/W that allows all the requirements to be met. If the weight of the vehicle has been assessed, the designer can extract the required wing area and thrust, allowing engine selection to be undertaken. Of the three optimum points in Figure 3-...
