عندي مجموعة أسئله تحتاج الى حلول نموذجيه متكاملة وان شاء الله سأجدها عندكم


when you weight your self,how does the support force of the scale
acting on you comparewith the gravitational force betweenyou and Earth??

.................................................

If you push an object at constantvelocity ,how do we know how much friction acts on the object
compared to our pushing force??

................................................

suppose you push to the right on a heavy piece of furniture but not hard enough to make it slide .Does a friction force act on the furniture?

................................................

why do we say velocity is a vector and speed is not??

................................................

How can you be at rest and moving at 100,000Km\h at the same time??
