Answers
Answer:
Your answer 1 ) SI unit is m/s2. ...
2 ) The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.
3 ) The value of acceleration due to gravity increases as we move from equator to pole.
4 ) The factors affecting the value of g are the shape of the earth, altitude and depth below the earth's surface. ... At the surface of the earth, the value of g is maximum (9.832m/s2) at the poles as the polar radius is minimum , while it is minimum (9.78m/s2) at the equator as the equatorial radius is maximum.
5 ) Differentiate between gravitational constant (G) and acceleration gravity (g) ?
Gravitational constant (G) Acceleration gravity (g)
Universal gravitational constant is a constant value at any place in the universe. The nature of the acceleration due to gravity varies from place to place.
Explanation:
Here is your answer
Answer: 1: the acceleration of freely falling bodies is called acceleration due to gravity.It is denoted by 'g'. the unit of gravitational acceleration is (N/kg).
2: Acceleration due to gravity is independent of mass. These two quantities are independent to each other. Light objects accelerates more slowly than heavier objects. When force other than gravity works.
3: the distance at the poles is smaller than that of the equator hence we can say that person has more acceleration due to gravity on the poles than the equator. the value of acceleration of gravity increases as we move from equator.
4: The factors affecting the value of g are the shape of the earth, altitude and depth below the earth surface.
5: G :- *it is universal gravitational constant.
*its numerical value is 6.673*10^-11 Nm2kg-2.
*it remains constant everywhere.
g :- * it is acceleration due to gravity.
*its numerical value is 10ms^-1.
*it decreases with increase in altitude.
