The Lab Environment Spend a few minutes to understand/explore the functionalities of the different tabs/components Force on m2 by m1 = 0.000 000 021 604 N Force on m1 by m2 = 0.000 000 021 604 N 01 Mass 1 50 kg Mass 2 200 kg Move the slider(s) to change the values of the two masses Instructions 1. Hold and drag the two masses to adjust the distance between the two masses. Let it is 2. Drag the sliders to adjust the two masses. Let these masses are M, and My. 3. Note down the values of the forces exerted by the two masses on one another. Since these forces will be equal in magnitude and opposite in direction, select any one and let it is F₁, that is force on mass 2 because of the mass 1. It can be noted that the force exerted by the mass 2 on mass 1 will be F, and is of the same magnitude Gravitational force depends on the masses and the distance. Newton developed the following equation to describe quantitatively the magnitude of the gravitational force if distance r separates masses my and m₂: Newton's Law of Universal Gravitation mm₂ ✔Show Values Constant Radus gravitational force=constant x 4. We can make the G as subject of formula, that is mass 1 x mass 2 (distance between masses)² Gis called the constant of universal gravitation. The value of Gwas unknown in Newton's day, but experiments have since determined the value to be as follows: G=6.673 x 10-11 Nm²
