An object moves freely upward.  The acceleration at maximum height is  

I am confused.  When at max velocity, velocity is zero.  But at that point gravity is negative or -g, magnitude is g. Is accleration at maximum height zero?  Please explain the rest.


Expert Answer

Step 1

When an object is freely moving under the influence of gravity, the motion of the object in free fall. In free-fall motion acceleration of the object is equivalent to acceleration due to gravity.

Step 2

Sign convention: In general acceleration toward upward from the earth is considered as positive and toward downward it is considered as negative. The same sign convention is considered for velocity and displacement.

Step 3

The motion provided in the question is free fall. Therefore, acceleration of the object throughout the motion will be equiv...
