The vernier constant is the ratio of the smallest division of the main scale to the number of divisions present in a vernier scale. Vernier constant is a term used in the measurement of length, particularly in instruments such as vernier calipers and micrometers. It is a dimensionless quantity that represents the value of the … Read more
The exponential of the primary quantities in a physical quantity is called the dimension of that quantity.In physics, a dimension is a measure of the physical size of an object or system. It refers to a property of space or time that can be used to describe the position, orientation, or movement of objects. In … Read more
A body is said to have uniform velocity if it covers equal distance in equal intervals of time in a particular direction, however the time intervals may be.
After applying break, a retarding force causes the velocity of a moving car to gradually decrease. That means negative acceleration or deceleration takes place. Because of this negative acceleration, the velocity of a moving gradually decreases to zero and comes to rest.
The rate of decrease in velocity of a body with time is called retardation or deceleration. The preferred term in physics to describe the decrease in an object’s velocity is deceleration. Deceleration is simply the negative of acceleration or a change in velocity where the final velocity is less than the initial velocity. It is … Read more
Quantity is a property that can exist as a multitude or magnitude, which illustrate discontinuity and continuity.
