السلام عليكم ورحمة الله وبركاته. أولا جزاك الله خيرا على المجهود الذي بذلتيه وبإذن ستكون في موازين حسناتك لأنك فرجتي عني كربته .
بما انك معنا اليوم نريد ان نستفيد من علمك . وهذه 3 أسئلة.
1- gravity on the surface of the moon is only 1/6 as strong as gravity on the earth.what is the weight (in newtons) ofa 10 N object on the moon and on the earth? what is the mass on each ?
2- what is the work done whena force of 5N slides a 1kg book across a table a distance of 2 m ?
3- this question is typical on some driver,s license exams : a car moving at 50 km/h skids 15m with locked brakes . How far will the car skid with locked brakes at 150km/h ?
ولن أنساكم بالدعاء .............................................
