The equation for determining the net force acting on an object is F = ma, or force equals mass times acceleration. Net force is measured in terms of acceleration, which means a change in velocity. If there is no change in velocity, the net force is considered to be zero.
At any time, there can be many forces acting upon an object, including gravity, friction and any external forces pushing or pulling on the object. The net effect of all of these forces is determined by the acceleration of the object. Acceleration is observed when a stationary object begins to move, a moving object changes speed or when an object in motion changes direction.Learn More
A spherical capacitor consists of two hollow, concentric spheres of oppositely charged electrodes with an insulator in between them. Physicists consider Earth to be a huge spherical capacitor surrounded by the ionosphere, with a charged atmosphere that discharges electricity to the surface of the planet in the form of lightning.Full Answer >
Atomic bombs work by splitting atoms, while hydrogen bombs, also known as nuclear bombs, draw their energy from fusing atoms together. While both types of reactions involve the nucleus of the atom, and both can therefore rightly be called "nuclear," tradition has reserved the word for the types of reactions that are exclusive to fusion devices.Full Answer >
Energy transfer is the conveyance of energy from one item to another; the transfer occurs among different scales and motions. Energy transfer may mean different things in different sciences.Full Answer >
