Why gravitational force is conservative??

Yogita Ingle 7 years, 2 months ago

A conservative force is a force with the property that the work done in moving a particle between two points is independent of the path taken. The gravitational force is conservative because the work done by the gravitational force on an object depends only on its change in height.

Light year is the distance travelled by light in one year. And a parsec is defined as the distance at which one astronomical unit subtends an angle of one arcsecond,[1] which corresponds to 648000/π astronomical units. One parsec is equal to about 3.26 light-years (30 trillion km or 19 trillion miles) in length.

Tendency of an object following a curved path to fly away from the center of curvature. Might be described as “lack of centripetal force.” No; centrifugal force is the inertia of motion. The direction of centrifugal force is the radius of the circle, from the center towards the object.

Vector

Pavas Bhatnagar 7 years, 3 months ago

Since force is a vector quantity, impulse is also a vector in the same direction. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the same direction. thus it can be concluded that impulse is a vector quantity
