About this Poster. This worksheet is appropriate for high school students of IGCSE, ICSE, CBSE, 5 views. Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics.They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. Statement ”Every body in the universe attracts every other body with a force Newton's law of universal gravitation states that a particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Q 2 Weight of an object on earth and moon is different. Gravitation is an important chapter in the Class 9 Science syllabus. from the equation (1) and (3) $$\vec F_{12} = - \vec F_{21}$$ Hence, it is clear that the applied forces are equal and opposite. The universal law of gravitation successfully explained several phenomena which were believed to be unconnected: (i) the force that binds us to the earth; (ii) the motion of the moon around the earth; (iii) the motion of planets around the Sun; and (iv) the tides due to the moon and the Sun. 1.
