Expression for escape velocity
Consider an object of mass 'm' placed on the surface of the earth. According to Newton's law of gravitation, the gravitational pull of the earth on that object is given by Where F is the force of attraction between the earth and the object, M e is the mass of the ..

All bodies when projected vertically upwards fall back to earth due to the earth's gravitational pull. The maximum height attained by a body depends upon the initial velocity of the body. This does not mean that no object can escape earth's gravitat..
Numerical value of acceleration due to gravity on Earth
Gravitational Constant (G) = 6.6734x10 - 1 1 Nm 2 /kg 2 Mass of the Earth (M e ) = 6x10 2 4 kg Radius of the Earth (R e ) = 6.4x10 6 m The value of acceleration due to gravity on Earth is 9.8m/s 2 . This means that when a body falls freely toward..

Acceleration due to Gravity 'g' - Bodies allowed to fall freely were found to fall at the same rate irrespective of their masses (air resistance being negligible). The velocity of a freely falling body increased at a steady rate i.e., the body had acceleration. This acceleration..

A space ship is launched from Earth with an escape velocity into the space. The path of the ship is a parabola with the center of Earth as the focus as shown. Find the equation of the parabolic path of the ship when d = 4500.(Assume that Earth is a ..
Centre of Gravity
We know that the earth attracts every particle towards the centre. A body can be considered to be made up of number particles. As the size of the body is small when compared to that of the earth, the gravitational pull acting on these particles can be regarded to be parallel to..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Even though I don't feel good, the tutor helped me by totally helping me understand!
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
The tutor let me do the work and corrected me when i made a mistake. They didn't just show me how to do it. They gave me instructions. We managed to do several problems.I really like this service - cindy
