Newton’s law of motion First law: Everybody continues in its state to rest or of uniform motion in a straight line except in so far as it is compelled by an external force to change that state. Second law: The rate of change of momentum of a body is directly to proportion to its force and change of… Read More »
What is velocity? or Define of Velocity. Velocity: The rate of change of displacement with time is called velocity. It is denoted by V. If the displacement of the object is s or time t, Velocity/ Linear velocity: The rate of change of displacement with time is called velocity. It is denoted by v. If the displacement of… Read More »
What is Mechanics ? or Define of Mechanics. Mechanics : Mechanics is an area of science concerned with the behaviour of physical bodies when subjected of force or displacement and the subsequent effect. It is a branch of classical physics that deals with particles that are either at rest or are mvoing with velocities.
