I have a bit confusion about the term force in general sense. Suppose a body is at rest in the ground, say this to be point A. Then, a force F is applied to it upwards which sends it accelerated against the gravity. Now my confusions are:
"In point A, the initial velocity of body is 0. Due to force in upward direction it's velocity will gradually start increasing in upward direction. At point B the velocity will be u1 (say). u1 is greater than 0. Then due to effect of gravity the velocity will decrease again slowly. At point C, the velocity will be u2 (say). u2 will be equal to zero. Then the body will start accelerating downwards under the effect of gravity" - Is the statement correct? If not, please correct me
In point A, the force is applied to move the body in upwards direction. Now say at any arbitrary point B, what will be the force acting? Does the question even make sense? I don't know if force will act after the body is punched from the point A in upwards direction.
