Acceleration is caused by a net force that is not zero (according to newtons second law)

@MTM ok i know that but i still dont have an answer

OpenStudy (anonymous):

for accelerating a body force must be applied so we hve to do a work therefore Energy causes acceleration but in the case of a freely faillung bdy gravity also provides acceleration

im going to go with energy then because i dont think gravity makes it excelerate because once its at 9.8 m/s it stops

OpenStudy (anonymous):

nope im going with gravity because thats the answer lol
