    Attraction and gravitational force.

    take two masses M1 and M2. problem says that M1+M2= 4. Newton's law of gravitation says that force between two objects of mass M1 and M2 is F = (gravitational constant) x (M1) x (M2) / (square of the distance) so u know F, gravitational constant, the value of distance...

    Why is a particle at rest while accelerating?

    this example is when we analyse things in the gravitational field. Its a kind of conservative field. if a particle is placed anywhere near the surface of the Earth it possesses potential energy by virtue of its position. Similar is the electromagnetic field. But suppose we...

    Why is a particle at rest while accelerating?

    if a particle didn't move the distance dx, how can it have velocity then? m pretty confused. Is there any mathematical justification? is thr any mechanics stuff that u want me to go through so that i can make myself clear?

    Why is a particle at rest while accelerating?

    Homework Statement consider a particle moving in a straight line and assume that its position is defined by the equation, x= 6(t^2) - (t^3) Homework Equations v=dx/dt= 12t - (3t^2) and a=dv/dt= 12-6t The Attempt at a Solution the...

    Objective question related to aerodynamics

    the total pressure is eqal to dynamic pressure plus the static pressure. but when a flow is brought to rest, the dynamic pressure becomes zero. the only pressure left is static pressure.when the flow is at rest the pressure at a point is same in all directions.But i dunt know how to coordinate...
