... will always happen – the acceleration will be the same direction as the net force (this is from Newton’s 2nd law) At this point it should be clear why the eraser slowed down and stopped. The acceleration was to the left – opposite the velocity, so the speed decreased. We will return to this example ...

... Block A in the diagram below weighs 1.50 N and block B weighs 4.30 N. The coefficient of kinetic friction between all surfaces is 0.20. Find the magnitude of the horizontal force, F, necessary to drag block B to the left at a constant speed if A and B are connected by a light, flexible cord passing ...

... Whatever the reason, they're missing an opportunity to experiment with rotational motion, balance, levers, and mechanical advantage. Seesaws turn out to be a wonderful context in which to explore the physics of rotational motion. So I've stuck with them, even as they've somewhat abandoned me. If you ...

... Feedback: Make sure that you don't justify the correct answer (no) on the basis of gravitational energy mgh. We are told that the initial height of the dropped disk is negligible, so, we must neglect it in our considerations. That means nothing undergoes a non negligible elevation change in the proc ...

Newton`s third law
... ball (mass = 100 g) is suspended on a 60 cm long string. When a charged rod is brought near the ball, the rod exerts a horizontal electrical force Felec on it, causing the ball to swing out to a 20° angle and remain at rest there. What is the magnitude of the electric force Felec? What is the tensio ...
