Variables Affecting Gravity | Mass & Distance from Chapter 5/ Lesson 13 81K Learn the definition of gravity as an attractive force, and understand how both mass and distance affect gravity. Explore other variab
wire, metal or other material that swings back and forth. Pendulums are used in everything from grandfather clocks to metronomes. Scientific principles govern what affects the swing rate of the pendulum, and there are surprisingly few variables that affect a pendulum's swing. Pendulums have fasc...
Find the change in electric potential energy between two charges that are initially a distance r1 apart and later a distance r2 apart. Use variables only. In order to keep an object moving at a constant speed, assuming yours is the only force acting on the object, how much force would yo...
In thermodynamics, any quantity can be derived from the so-called thermodynamic potentials: entropyS(N,V,E), enthalpyH(N,P,S), Helmholtz’sF(N,V,T) or Gibbs’sG(N,P,T) free energy, and grand potential\(\Phi (\mu , V, T)\), depending on the thermodynamic variables one controls:...
These changes are mostly driven by the gravitational pull of Jupiter and Saturn, according to NASA, and affect the length of our seasons. With a nearly circular orbit, the length of the seasons is about equal, but as the orbit becomes more elliptical, the length of the seasons will start...
That's a whole lot of variables, which means it's very hard to give an all-encompassing, reliable answer to the timeline of a body's decomposing process. However, it's entirely possible to give ballpark figures to its various stages, as long as we know the specific circumstances of the...
(e.g., the electron). The three non-gravitational forces are associated with (gauge) bosons, carrying spin 1. Virtual photons (\(\gamma \)) mediate the electromagnetic force, virtual gluons (g) the strong nuclear force, and virtualZand\(W^\pm \)bosons the weak force. The Higgs ...
Many people think that space and time are completely different variables, but physicists often combine them into “space-time”. Space-time is a four-dimensional coordinate system used in relativity and other areas of physics. The dimensions are, length, width, height, and the 4th is the time...
It is typically caused by contact or gravitational attraction, and it is measured in Newtons (NN). In order to understand how forces affect motion, one needs to understand concepts such as momentum, impulse and work. Kinematic equations are often used to calculate force based on t...
from Chapter 3 / Lesson 4 44K Learn about the different types of force that can affect the universe. Explore gravity, friction, electromagnetic force, elastic force, and tension. Discover the different ways each can pull or push an object. Related to this QuestionA...
