If you tossed an object either up or down and could somehow eliminate the effects of air on its flight you would find that the object accelerates downward at a certain constant rate. The rate is called the free fall acceleration and its magnitude is represented by g. The acceleration is independent of the objects characteristics such as mass density or shape it is the same for all objects.
Assertion(A): The weight of the of an object decreases as it moves from poles to equator. Reason(R): The earths radius is larger at the equator than at the poles.
Assertion(A): The acceleration due to gravity is maximum at the surface of the earth. Reason(R): Gravitational force decreases with altitude and depth from the Earth's surface.
Weight on Different Planets An astronaut weighs 700 N on Earth. The table below shows the acceleration due to gravity on different planets. Planet | Acceleration due to gravity (m/s2) Earth | 9.8 Mars | 3.7 Jupiter | 24.8 Moon | 1.6
Variation of graph with altitude The following graph shows how the gravitational acceleration g varies with altitude h from the surface of the earth.
The mass and radius of earth is reduced to half the acceleration due to gravity would
