The influence is negative because gravity is pulling downwards while the ball is trying to move upwards. And the acceleration working on the ball at this point is the acceleration due to gravity (g) and this time its considered positive i.e. downwards as the ball is now ready to free fall. Differently, we can say that the KE availed by the thrown object gets corroded under the negative influence of oppositely directing gravity (Gravitational force due to earth). The acceleration is negative because this acceleration is directing downwards while the ball is moving upward.And because of this negative acceleration, the velocity of the ball is gradually decreasing. (Acceleration due to gravity = 10 m/s) 2) A stone is thrown down vertically from the top of a tower with initial velocity of 10 m/s. This velocity is attained by the vertically falling ball just before touching the ground.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[320,50],'physicsteacher_in-narrow-sky-2','ezslot_22',158,'0','0'])};__ez_fad_position('div-gpt-ad-physicsteacher_in-narrow-sky-2-0');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[320,50],'physicsteacher_in-narrow-sky-2','ezslot_23',158,'0','1'])};__ez_fad_position('div-gpt-ad-physicsteacher_in-narrow-sky-2-0_1'); .narrow-sky-2-multi-158{border:none !important;display:block !important;float:none !important;line-height:0px;margin-bottom:7px !important;margin-left:auto !important;margin-right:auto !important;margin-top:7px !important;max-width:100% !important;min-height:50px;padding:0;text-align:center !important;}. And the maximum height H reached is obtained from the formula: v22=v12-2gH ( under negative acceleration) (iii).
