scalar field define with example
what is displacement
the change in the position of an object in a particular direction is called displacement

what is oscillation
Bernoulli's equation which applies a fluid flow states that P+h✓g+½PV²=k. where ✓=density. P=pressure. h=height. V= velocity. g=acceleration due to gravity. k= constant. Show that the equation is dimensionally constant and show the S.I unit for k.
The nature of physics
what physics
Darshan
Physics deals with nature and its natural phenomenons
Sushant
physics explains more about mechanics and other natural phenomenon.
Ferdinand
define realitives motion
Relative motion is the calculation of the motion of an object with regard to some other moving object. Thus, the motion is not calculated with reference to the earth, but is the velocity of the object in reference to the other moving object as if it were in a static state.

I am unable to access the mcq can someone help me with it?
What is free fall?
when an object is falling under the the influence of the earth gravitational force, the term is called free fall.
Bra
V=E½-P-½ where v; velocity, P; density and E; constant. Find dimension and it's units of E (constant)

derivation of simple harmonic equation
if an equation is dimensionally correct does this mean that equation must be true?
how do I calculate angular velocity
w=vr where w, angular velocity. v; velocity and r; radius of a circle
michael
sorry I meant Maximum positive angular velocity of
Priscilla
please can u tell me the formular for tension in angular velocity I kind of forget it please don't ignore this msg I need it nw
sodeeq
Does the mass of the object affect the rate at which it accelerates ?
