Unbalanced forces cause accelerations.
In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down. To verify if the forces acting upon an object are balanced or unbalanced, an analysis must be conducted to verify what forces are acting upon the object and in what direction. If two individual forces are of equivalent magnitude and opposite direction, the forces are balanced. An object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of euqivalent magnitude and in the opposite direction
What is Centrifugal Force? Centrifugal force is the force that is equivalent in magnitude but opposite in direction to the centripetal force, which is the force directed toward
Optical interference process is broadly divided into two categories namely (i) division of wave front (ii) division of amplitude. Give one example for each category of interference
When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
What is a hypothesis for a Hooke''s Law experiment which was completed with a single, series and parallel spring arrangement?
It is the phenomenon of emission of electrons from the surface of metals, when light radiations (Electromagnetic radiations) of suitable frequency drop on them. The emitted electro
Define Hole in Wall (Princeton)? A container is separated into two parts I and II by a partition with a small hole of diameter d Helium gas in the two parts is held at temper
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:
Violet light (λ = 415 nm) falls on a slit that is 0.040 mm wide. The distance among the centers of the central bright band and the third-order dark band is 18.7 cm. What is
Calculate the density of silver which crystallizes in the face-centred cubic structure. The distance between the nearest silver atoms in this structure is 287 pm. (Molar mass of
