Exp. An odometer or odograph is an instrument for measuring the distance travelled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two.


Exp. The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg•m−1•s−2). This name for the unit was added in 1971. It is named after the French polymath Blaise Pascal.


Exp. The time taken by a pendulum to complete one oscillation is called its Time Period.


Exp. If the weight of an object is 60 kg then mass on the moon = Mass of an object in earth/6  =60/6=10N.                                  


Exp. The convex mirror produces an upright image of any object and offers a wide viewing area as compared to the plane mirror. The usage of this type of mirror can be perceived on the car rear-view mirror, side-view mirror and even the motorcycles.


Exp.  Ultraviolet (UV) radiation from the sun or sunbeds is the main cause of skin cancer.


Exp. It may seem that current is a vector because it have a magnitude and a direction. But the thing is, a vector always obey the law of addition of vectors. Since current doesn’t obey it and it follows algebraic addition, current is a scalar.


Exp.  The phenomenon of raising outer edge of the curved road above the inner edge is to provide necessary centripetal force to the vehicles to take a safer turn and the curved road is called Banking of Roads.


Exp. Pascal’s principle states that “a change in the pressure of an enclosed incompressible fluid is conveyed undiminished to every part of the fluid and to the surfaces of its container.” For every 10m depth the pressure on the diver increases by 1 atm so at a depth of 10 meters under water, pressure is twice the atmospheric pressure at sea level. Thus, during Scuba diving players must have the knowledge of Pascal’s law.


Exp. Least distance of distinct vision is defined as the minimum distance between the eye lens and the object to form a clear image. For a healthy human eye, the least distance of distinct vision is 25 cm, however it varies with age.
