What is the size of the gravitational force acting on the earth due to the sun?

The gravitational force between two objects of mass $m_1$ and $m_2$ separated by a distance $r$ is given as: $F_("grav")=G(m_1*m_2)/r^2$ Where $G$ is the Universal Gravitational Constant$=6.67xx10^-11 (Nm^2)/(kg^2)$

Using Newton's gravitational force equation $F=(Gm_1m_2)/(r^2)$ and assuming that the mass of is $m_1=5.972*10^24kg$ and $m_2$ is the given mass of the moon with $G$ being $6.674*10^-11Nm^2/(kg)^2$ gives $1.989*10^20...

With respect to each, use $"Force" = "Mass" xx "Acceleration" = gamma(mM)/r^2$. So the accelerations towards the other are in the inverse ratio of their masses. The mass of...

In all the spontaneous processes where heat is transferred from a body of higher temperature to a body of lower temperature, entropy always increases. To learn why, check...

We know because of all the data collected by scientist and satellites. But there are some observations you can do to determine for yourself what orbits what. 1 / Let's...

As 0.5 degrees is quite a small angle the diameter of can be calculated as $rθ$, where r is the distance to the Sun and θ is the angle in...

IAU (International Astronomical Union) AU = 149597870.7 km. 1 light year (LY) = 6.29 E+04 AU. For the precision in measurements of angles, all the significant digits (sd) in size...

Velocity is defined as the rate of travel, and can be found using the distance formula. $"velocity" = "distance"/"time"$ Rearranging this formula we can solve for distance given velocity and...

Light takes about 5.5 hours to reach Pluto from . If you know the time that light takes to reach certain object, you can deduce the distance to that object...

The radius of the Earth is approximately $4000$ miles. Gravity obeys an inverse square law, decreasing by the square of the distance from the centre. So the gravitational acceleration due...
