The force of gravity causes objects near Earth's surface to fall with constant acceleration of 9.8 meters per second squared unless air resistance is substantial. Keep in mind that the integral of acceleration over time will yield velocity. Multiply the length of time the object has been falling...
Even the light physicists use to help them better see the objects they're observing can influence the behavior of quanta. Photons, for example -- the smallest measure of light, which have no mass or electrical charge -- can still bounce a particle around, changing its velocity and speed. ...
Calculate the acceleration of a person or object by dividing the change in velocity by the time over which the change took place. For example, consider a race car that starts from rest, or zero mph, and accelerates to a final velocity of 155 mph in 6.1 seconds. A velocity of 155 mph ...
The greater the object's mass, the larger its event horizon and the larger its radius. Regardless of how massive it is, a black hole's center point is what astronomers call a singularity -- a place where matter is infinitely dense. Of course, you'll have to find one of these objects...
You can't get torque out of 660cc at that low rpm. The velocity and mass isn't there for the torque you want. That's why you have to spin them up.. The only way your going to make it is with displacement. The F10A with the right parts will bolt in since Super Carry's used ...
He used the term "dark matter" to describe the unidentified mass required to cause this surge in velocity. A year later, Fritz Zwicky began studying galaxies in the Coma cluster. Using luminosity measurements, he determined how much mass should be in the cluster and then, because mass and ...
When sprinters run with the wind at their backs, they can reach higher speeds. Similarly, if you jump in an area where the wind is blowing upward , you can reach greater heights. It takes strong wind to push you upward—wind blowing faster than your terminal velocity . Your terminal ve...
If you're moving, you have energy—kinetic energy to be precise. Kinetic energy is simply the energy an object possesses because it has both mass and velocity (speed in a certain direction). The more mass you have (effectively, the heavier you are) and the faster you're going, the ...
In addition, these tunnels can help engineers figure out how wind interacts with stationary objects, such as buildings and bridges, and find ways to make them stronger and safer. In short, many of our modern marvels are more advanced thanks to wind tunnels. But it was the dream of flight ...
Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves. EM radiation can range from very low energy to very high energy, and we call this span the electromagnetic spectrum. Within the EM spectrum, there are two types of radiation -- ionizing and non-ionizing....
