an unloaded truck weighing 2000kg has maximum acceleration of 0.5 m/s sq. what is the maximum acceleration when it is carrying a load of 2000kg ?
In this question,we are calculting 2 different masses of same truck. but we have studied that mass is constant, only weight changes.........
please clarify the topic................is force =weight or mass

See, you're correct with the point that mass is constant. But see the question again. It is mentioned 'weighing', not 'of mass'. So the weight of the truck changes in the two cases, not its mass. And Force is weight, weight is the gravitational force pulling on a body. It is also equal to mass multiplied by acceleration. I hope your doubt is clear now.
Plz mark as brainliest :D

poojaoberoi: But the SI unit of mass in Kg and the SI unit of weight is Newton. so how can you link weight with Kg.............please plz help me....... thanks

chiefLucky: That is the thing. When you multiply force(which is newtons) by acceleration due to gravity(10 m/s2), you get its weight in kg. Kg is also N m/s2, which means force multiplied by acceleration!

poojaoberoi: thanks
