Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four fundamental forces in the universe. But none of those facts answers the most basic question: What exactly makes a magnet stick to certain metals? Or why don't...
Thespecific gravitystands for a dimensionless unit that defines the ratio of density of a substance to the density of water. The density of water is 1000 kg/cubic meters at 4 Celsius. In physics, the weight of the substance differs from its mass. The weight is the gravitational force that ...
It is the downward force of gravity that makes this thermometer work. The basic idea is that as the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As the temperature of the water changes, it either expands or contracts, ...
On Earth, the acceleration of gravity generally has a value of 9.806 m/s2 or 32.1740 f/s2. Since this is just a different scale for measuring acceleration, it not only applies to gravity, but can be used to quantify any acceleration. How g-force relates to harsh driving As mentioned, ...
The force of ejecting at those speeds can reach in excess of 20 Gs -- one G is the force of Earth's gravity. At 20 Gs, a pilot experiences a force equal to 20 times his or her body weight, which can cause severe injury and even death. Most military aircraft, NASA research ...
The ability of a gyroscope to "defy gravity" is baffling! How can it do that? This mysterious effect is precession. In general, precession works like this: If you have a spinning gyroscope and try to change the orientation of its spin axis, the device will respond by changing its orient...
Weightis the amount offorcewith which Earth'sgravitypulls on a particular mass: the more massive something is, the more gravitational force, and the more we say it weighs. Like any other force, we should measure weight in newtons.
Is tension force and normal force the same? How to find tension on an inclined plane At what rate would a 20 kg box accelerate if it were pulled to the right with a 100 N tension at a 40° angle, in m/s^2? Why is the tension force equal to mass x gravity on an inclined ...
