Explain about gravitational work. Give its unit.

1.	Explain about gravitational work. Give its unit.
Answer» 1. When an object is raised to a certain height against the gravitational field, gravitational work is done on the object. 2. For example, if an object of mass ‘m’ is raised through a height ‘h’ against acceleration due to gravity ‘g’ , then the gravitational work carried out is ‘mgh’. w = m.g.h w = Kg .ms^-2.m w = Kg m² s^-2 w = Joule

Answer»

1. When an object is raised to a certain height against the gravitational field, gravitational work is done on the object.

2. For example, if an object of mass ‘m’ is raised through a height ‘h’ against acceleration due to gravity ‘g’ , then the gravitational work carried out is ‘mgh’.

w = m.g.h

w = Kg .ms^-2.m

w = Kg m² s^-2

w = Joule
