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.
200 N force means-
The physical quantities which are independent or neutral that is, they do not depend on other quantity, rather other quantities depend on them, are called fundamental quantities. What is fundamental quantity? In physics and other sciences, a fundamental quantity is a physical property that can’t be expressed in terms of any other physical quantities. It’s … Read more
Velocity is the rate of change of displacement with respect to time.
The rate of change of velocity with time is acceleration. If there is a change of velocity in magnitude or direction or in both, there is an acceleration. But if the velocity doesn’t change, there is no acceleration.
Heartbeat is a type of periodic motion. The heartbeat can be classified into two main types of motion, depending on how you look at it: 1. Periodic motion: When viewed from the perspective of time, the heartbeat is a periodic motion. This means that it repeats itself at regular intervals, with each cycle consisting of a … Read more
Physical quantities which need both magnitude and direction to be fully expressed are called vector quantities. Displacement, velocity, acceleration, force, electric intensity etc are the examples of vector quantities. A vector quantity is a physical quantity that has both magnitude and direction. This means that in order to fully describe a vector quantity, you need … Read more
