Where anet is the net acceleration on the simulated insect’s body. g is gravitational acceleration, c is the drag constant, and v is the velocity vector of the simulated insect. Here, (t−1) refers to the value from the previous time step. This net acceleration is then added to the...
Where c is a constant reflecting the deceleration due to drag for a given airspeed,gis gravitational acceleration (scalar), andvtis the insect’s terminal velocity (scalar). Within our simulations of the three behavioural motifs, we used a constant of 0.80 s−1with a terminal velocity of...
In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you ...
getting a fuller picture of dark energy’s influence. “The Universe expanding is like a rubber band being stretched. If dark energy is not constant, that would be like stretching the rubber band by different amounts at different points
Near the Earth's surface, this constant is given its own special variable: g. "Little g," as g is often called, always has a constant value of 9.8 m/s2. (The phrase "little g" distinguishes this constant from another important gravitational constant, G, or "big...
Why is math so heavy in a black hole? Define Gravity and write its formula. Why are heavier elements not much larger than lighter elements? Within the visible Universe, is the sum of all gravity constant? If not, then why not? How is electricity stronger than the gravitational force? Why...
Gravity constantly pulls things down when it enters the earth’s atmosphere. Why does earth have a gravitational pull? Earth’s have a gravitational pull that keeps us on the ground so we won’t float off in space. What is the earth’s atmosphere made of? earth’s atmosphere has 78% ox...
What is the unit for magnitude of acceleration? If weight is measured in Newtons, then why do we measure our weight in pounds or kilograms? Could we replace Newtons with pounds or kilograms when solving problems in Physics? What are the units...
For me there is only one question remaining. From what I understand of SR and GR, when we dig deep enough we find that the constancy of C for all observers lies at the base of both theories. Can we say why C is constant for all observers? Is there a more fundamental statement ...
Next, we look at Newton's law of gravity, where G is the gravitational constant and M the mass of the sun, m the mass of the Earth, and r→ the coordinate direction of the force. F=−G⋅M⋅mr2⋅r→ and his second law of motion, which states that a force ...
