d) Q: What is the sign of the acceleration when speeding up and moving in the positive direction? e) Q: What is the sign of the acceleration when speeding up and moving in the negative direction? f) Q: What is the sign of the acceleration when slowing down while moving in the positive direction? g) Q: What is the sign of the acceleration when slowing down while moving in the negative direction? h) Q: For the following acceleration graph, is the motion in the negative or positive direction, or is it impossible to tell? Explain your answer.Explanation / Answer
d) first ofcorse the acceleration will be positive as speeding up or has positive velocity therefore the acceleration will have same direction in the dirction of velocity. it will be (+)
e)If an object is speeding up in the negative direction then it will having a negative velocity also the direction of acceleration will be negative same in the direction off velocity. (-)
f))If an object is slowing down in the positive direction then according to a slowing down object principle the acceleration will be opposite to velocity direction always i.e negative acceleration (-)
g)If an object is slowing down in the negative direction then according to a slowing down object principle the acceleration will be opposite to velocity i.e positive acceleration (+)
