The Earth Our Habitat gives an introduction to the major geographical aspect of our planet. This subject is further divided into 8 chapters which are important for the exams. The Class 6 geography NCERT Social Science Chapter 8 is named India: Climate, Vegetation and Wildlife Acceleration due to gravity of the earth. Acceleration attained due to gravity of earth. All the objects fall towards the earth because of gravitational pull of the earth. And when abody is falling freely, it will have some velocity and therefore it will attain some acceleration. This acceleration is known as acceleration due to gravity The internal structure of Earth, structure of the solid Earth, or simply structure of Earth refers to concentric spherical layers subdividing the Solid earth, i.e., excluding Earth's atmosphere and hydrosphere.It consists of an outer silicate solid crust, a highly viscous asthenosphere and solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core Question 8.15 A body weighs 63 N on the surface of the earth. What is the gravitational force on it due to the earth at a height equal to half the radius of the earth ? Question 8.16 Assuming the earth to be a sphere of uniform mass density, how much would a body weigh half way down to the centre of the earth if it weighed 250 N on the surface Gravitational force on the surface of the moon is only 1/6 as strong as gravitational force on the earth. What is the weight in Newton of a 10kg object on moon and on the earth? Answer. Given, mass of the object, m = 10kg. Weight on the earth, w = mg = 10×9.8 = 98 N. Weight on the moon = 1/6(weight on the earth) = 1/6(98) = 16.33 N 14
For example, when an object is attracted by the earth's gravitational force, the object attracts the earth with an equal an opposite force. According to Newton's second law, an object's weight (W) causes it to accelerate towards the earth at the rate given by g = W/m = 9.8 meters / s 2 , where m is the object's mass Morning Star solutions for ICSE Class 9 Total Geography chapter 8 (Earthquakes) include all questions with solution and detail explanation.

Day & Night 8. • The part of the earth that is facing the sun experiences day-time The acceleration of gravity (also referred to as the gravitational field strength) at the surface of the earth has an average of 9.807 m/s^2, which means that an object dropped near earth's surface will accelerate downward at that rate. Gravity is a force, and according to Newton's Second Law, a force acting on an object will cause it to accelerate: F=ma Acceleration is a rate of change of.
