Each particle produces a gravitational field around it which exerts the gravitational force on each of the other particles present within this region. The portion around a point mass in which each other point mass experience a gravitational force, is known as the gravitational field i.e. The intensity of gravitational field at point is the gravitational force exerted on a unit mass reserved at that point.
The force performing on a particle of mass m placed at a distance r from the centre of earth is given by
If a ring were constructed as knid of a space station. How fast must a 50.0-m-radius ring rotate to simulate Earth's gravity?
A 250 N crate is sitting on a 30 degree inclined plane. The frictional force is larger than the component of the crate's weight parallel to the inclined plane, so that the crate do

Logan, whose mass is 18 kg, sits 1.20 m from the center of a seesaw. If Shiro must sit 0.80 m from the center to balance Logan, what is Shiro's mass?
Q. Why there is no horizontal acceleration during projectile motion? Ans: The gravitational force (F)acting on the particle during its flight has only vertical component i.e. F(co
