Ppts about gravitational force of different planets
Answers
Explanation:
the gravitational force of different planets will be -Gm1m2/r²
Answer:
Every body in the universe exerts a gravitational influence on every other body. That includes human bodies, but the force is more important between more massive bodies, such as planets and stars. The gravitational force between two bodies on Earth is negligible, but not the attractive force between a body and the planet itself. It's the glue that prevents everything that isn't tied down from floating off into space.
In general, two bodies exert a gravitational force on each other directly proportional to the product of their masses and inversely proportional to the square of the distance between them:
F_g = G {(m_1m_2)\over R^2}F
g

R

(m

where G is the gravitational constant.
When one of the bodies is much larger than the other, as is true for Earth and anything on its surface, its mass predominates. Every object on Earth's surface is attracted to the center of the planet with a force proportional to its mass, giving rise to the adage: "whatever goes up must come down," which is true as long as the object isn't moving fast enough to leave the ground and go into orbit.
Other planets exert the same type of gravitational force on objects on their surface, but the magnitude of this force is different. It depends not only on the planet's mass, but also its density, because the denser a planet is, the more mass there is under your feet pulling you down.
