Motion of an object in a straight line is called one dimensional motion. The location of a particle in one dimensional motion can be explained by only one variable (say x). For a particle rolling along a straight line (1-D motion) all the vector quantities like velocity, position, acceleration and displacement have only one non-zero element.

What are the Semiconductor Devices? A semiconductor is a material whose conductivity is much less than a conductor (such as copper), but greater than that of an insulator (such
Q. Determine the elapsed time in kinematics? Let S = 1 + c 2 + c 4 + ........ Then, S = 1 + c 2 (1 + c 2 + c 4 +.......... ) S = 1 + c 2 S so, S - c 2 S = 1
What are the objectives to know about working of ultrasonics? Objectives of ultrasonics: a. Understand the term ultrasonics. b. Describe the principle, working and constr
KINEMATICS I 1. x(t) is called displacement and it denotes the position of the body at a particular time. If the displacement is positive then that body is to the right of
The energy band formed by a series of energy levels having valence electrons is called as valence band. At 0 K, the electrons fulfill the energy levels in valence band initialising
Explain the working of a refrigerator A refrigerator is the reverse of a heat engine. Here the working substance extracts heat Q2 from the cold reservoir at temperature T2, som
A tortoise can run with a speed of 0.12 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 4.0 minutes. The torto
Reflection of a Pulse at a Fixed End Let's assume a pulse moving by a medium - perhaps by a rope or a slinky. What happens to the pulse while it reaches the end of that medium?
