Simple harmonic motion is the motion of a simple harmonic oscillator, a motion that is neither driven nor damped. The motion is periodic, as it repeats itself at standard intervals in a specific manner - described as being sinusoidal, with constant ... more

There is no Normal Force because there is no gravity or weight acting downward to allow any normal force to be pushing upwards with. There is also no drag in the vaccuum of space and the vehicle is not accelerating so the net force of the system is ... more

Physics majors do very well. My students and physics students in general have no trouble getting jobs. The key to their success is that when they meet new technology they are able to figure it out based on their understanding of physics. They tend ... more

Active Physics provides real-world contexts and hands-on experiences to help students actively engage in learning. The CPU simulation software is an excellent complement to the Active Physics program, by enabling students to build powerful visual ... more

yes it is a luminous object. a luminous object is an object which emits lights, and when iron is red hot it absorbs all the colurs of light and reflects the red light becauze of which red hot iron is seen in red colour and it emits red light, thus ... more

John Dalton propsed the idea of atoms in their current form - as the smallest indivisible units of an element - this was in 1803.. In 1897, J.J Thompson discovered the electron. In 1911, Rutherford found that the atom consisted of a central dense ... more

Mark B has a good answer.I myself would suggest you get a magnetic compass,put it on a largish table with the electromagnet,say one metre apart with one poleface of the magnet east(or west )of the compass BEFORE you switch on the magnet.See if ... more

If you are using an electronic dimmer rather than just a variable resistor, then yes, it uses less power than when it is operating at full intensity. But it is much less efficient than a more efficient form of illumination operating at full ... more

As a child of divorced parents I felt it was my fault, it was hard because most of my friends parents were still together or had step parents. My mom never remarried so I never got to see what a healthy adult relationship looked like. BUT: I am so ... more

Dear, electron volt (eV) is the unit for energy in Atomic Physics and in Nuclear Physics. But the volt is not a unit of energy in any subject. Instead, it is a unit for voltage, potential difference or electromotive force (EMF). Because these two ... more
