How do you calculate your weight on Neptune?
How do you calculate your weight on Neptune? Being that it takes the weight of an object on earth and converts it to the weight on Neptune, the formula is Weight on Neptune= (Weight on Earth/9.81m/s2) * 11.15m/s2. To find the weight on Neptune, we divide the weight on earth by the earth’s force of […]

Why gravity is always attractive?
Why gravity is always attractive? In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces. […]
Does moving a piano put it out of tune?
