Acceleration = Force/Mass . A force of 20 N acts upon a 5 kg block. Calculate the acceleration of gravity on the object. Formula: Force = Mass X Acceleration or Acceleration = Force/Mass . 20N = 5kg X Acc or Acc = 20N / 5kg = 4m/s2. A force of 200 N is exerted on an object mass of 40 kg that is located on a sheet of perfectly smooth ice.

The larger the Star is the more gravitational force it will exert, pulling planets towards it, the planets will orbit more quickly and be pulled more strongly giving a more elliptical orbit. When the planet is larger it will orbit the star more slowly. The closer a planet is to its star the more quickly it will orbit, further away from the star ...

If the force were supplied by gravity, then it must be given by F = GMm/r2. ΣF = ma Assuming gravitational force is responsible and that the motion is circular yields. FG = m(v2/r) Substituting in Newton’s formula for gravitational force. GMm/r2 = mv2/r
Newton’s Law of Universal Gravitation | Boundless Physics
In the formula, m. 1. and . m. 2. are the magnitudes of the masses and . r. is the distance between their centers as shown below. G is a number called the “Gravitational Constant”, which relates the gravitational force in Newtons to the masses in kilograms and the distance in meters. Its value is 6.67 x 10-11 Nm2 /kg2 .
