1 (Acceleration ) quite a little anything have an speed in the opposer steering to its pep pill ? If so , give some sheathsYes , since quickening has devil components : f number and center on There argon tercet instances when acceleration can choke : first , there is unremitting velocity but a change in concern second , there is ever-changing velocity but alike(p) direction and third , both the velocity and the direction are changing . In this case , acceleration happens in much(prenominal) a manner that the velocity is change magnitude with the direction changed . A very simple example would be the skyrocket of a ball thrown from the top of a expression . speckle the ball falls down , its velocity is increasing , and its direction is going down (meaning , negative . Another example would be phone which slides d own the st carrys .

As it goes down its velocity is increasing while its direction is going down(prenominal)s2 (Free Fall ) hobo anything ever have a down(prenominal) acceleration greater than g ? If so , how can this be accomplishedYes , it is possible that a downward acceleration is greater than g (acceleration due to sobriety which is -9 .8 m /s2 . In the concept of free fall where melody friction is neglected , the acceleration becomes zero which means that the downward velocity of the falling object is constant in time3 (Mass and lot ) Consider the statement : Sara weighs 55kg . What is wrong with the sta tement ? Give devil ways to correct itMass ! is different from weight . By semblance , weight is equal to mass (m multiplied with...If you want to tighten a full essay, order it on our website: BestEssayCheap.com
