How High Will It Go?
The motion of the sledder within the animation below is same to the motion of a roller coaster car on a roller coaster track. The similarity of the two motions is related along with the work-energy relationship. The energy bar charts accompanying the animation depict this relationship. Energy bar charts are a conceptual tool amount the amount of each form of energy possessed through an object as it is undergoes a particular motion. Observe from the animation in which the total mechanical energy TME of the sledder remains constant by the motion.
a balloon is filled with 100 kg of helium, and that the velocity is 2.0 m / s what is the external kinetic energy?
A particle is projected from ground with velocity 40sqrt2m/s.find- a)velocity and b)displacement of particle after 2sec .Take g=10m/s^2 Ans) velocity v=u+at a=-g v=40√2-10*2
why electric field is zero inside a cavity
Suppose a fluid (say, water) occupies a domain D ⊂ R 3 and has velocity field V=V(x, t). A substance (say, a day) is suspended into the fluid and will be transported by the fluid
Voltage: Voltage is the electrical equivalent of mechanical potential. If a person drops a rock from the first storey of a building, the velocity it will reach when dropped wi
Photoelectric effect An effect described by A. Einstein that demonstrates that light appears to be built up of photons or particles. Light can do excite electrons (called phot
What are the branches of physics? The basic branches of physics are a) Classical mechanics b) Electromagnetism (including optics), c) Relativity, d) Thermodynamics,
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
how nicol prism is constructed?
Explain the Maxwell's equation in electromagnetism connecting magnetic field vector and electric displacement vector.
