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 valu
36 The Moon is in circular orbit around Earth at constant speed.(a)Explain why we describe the Moon as accelerating towards the Earth.[2](b)(i)Starting from the equation for circular motion show that the acceleration of the Moon bowards the Eath is nby=(4x^2R)/(T^2) 2where 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 ...
constant, that would be like stretching the rubber band by different amounts at different points,” says Möller. “I think in the next decade we will be able to constrain whether dark energy is constant or evolving with cosmic time. Rubin will allow us to do that with Type Ia sup...
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...
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...
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...
Milgrom has proposed that the gravitational 'constant' is not constant between objects of low relative acceleration. His MOdified Newtonian Mechanics (MOND) provides an alternative explanation to dark matter for the anomalous orbital velocities of spiral galaxy stars. Ontological Evolution in Everyday ...
