What has the strongest gravitational field?
Jupiter, the fifth planet from the Sun, has the strongest gravitational pull because it’s the biggest and most massive.
- Massive Gravitation.
- Jupiter and the Asteroid Belt.
- Almost a Star.
- Jupiter and Neighboring Planets.
Who found the value of G?
Henry Cavendish
How would the value of G and G be affected if the mass of Earth becomes four times?
Gravity is in g is equal to earth masses/earth radius^2. By increasing mass, we proportionally increase volume (assuming constant density). This means that 4 Earth would have a radius that is cube root 4 bigger than Earth. So due to the mass, the gravity increases by a factor of 4.
What will be the value of G if mass of Earth becomes four times?
4GM/r^2
How will the value of G be affected if?
Answer: If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
Does a parachute fall freely?
In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. By this definition then, a skydiver is never in true free fall, even before they deploy their parachute. Because the gravity of earth is the only force acting upon the moon.
Why does a person feel weightless during free fall?
When in free fall, the only force acting upon your body is the force of gravity – a non-contact force. Since the force of gravity cannot be felt without any other opposing forces, you would have no sensation of it. As such, you would experience a weightless sensation.
When a body is under free fall?
Equations. The best way to see the basic features of motion involving gravity is to start by considering straight up and down motion with no air resistance or friction. This means that if the object is dropped, we know the initial velocity is zero. Once the object is in motion, the object is in free-fall.
