Question

define weight and universal law of gravitation​

Answer 1

Answer:

Wieght It is force acting on a body.It depends upon 'g' acceleration due to gravity and the mass of the object.

• Universal Law of gravitation says that two object of mass say 'm' and 'M' attract each with Certain force . This force is directly proportional to the product of the mass of object 'm' and'M'and inversely proportional to the square of distance between them.
• F=G×m×M\radius square.
• G is the universal gravitation constant.
• 'G'=6.67×10 to the power -11 Newton .m square .kg power -2.

Answer 2

Answer:

Explanation:

Section Summary. Newton's universal law of gravitation: Every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
