A ball is thrown downward with an initial speed of 20 m/s on Earth. What is the acceleration of the ball?

Question

fifciol · Answer

the acceleration on Earth is given by the equation:
$$g=\frac{ G M_E }{ R_E^2 }$$
which on the surface of the Earth is about $$9.81 \frac{ m }{ s^2 }$$ It means that every mass near the surface of the Earth, while falling down gains the speed of 9,81 m/s in every second (if we neglect the resistive forces acting on mass). Do you think the acceleration depends on the velocity of an object?

shamim · Answer

g=acceleration due to gravity

shamim · Answer

g does not depend on any objects initial velocity

shamim · Answer

The value of g is constant for any object

shamim · Answer

Acceleration = rate of change of velocity
