... m but also depends on gravity. Weight does change if you go somewhere else. Therefore the answer is (2). 26. Based on Newton’s 3rd law, every action has an equal but opposite direction. If the student pulls the sled with 20. Newtons, the sled exerts exactly the same magnitude of force the other way. ...

... To derive the laws of circular motion the knowledge of vector addition, subtraction and motion laws will be applied. During circular motion the velocity vector permanently changes its direction as it is shown on Fig. 2.2-49. Two velocity vectors are named vFin (final velocity) and v 1n (initial velo ...

... You have now developed a model of how things move by considering work done on an object and the change in energy of the object. In the cases studied so far, you've only needed to concern yourself about constant forces (or in some cases, average forces, for which we don't have detailed information ab ...

... What is energy? When you have a lot of energy you can run farther or faster; you can jump higher. Objects, as well as people, can have energy. A stone falling off a high ledge has enough energy to damage a car roof. One way to summarize the examples of energy above is to say that an object has energ ...

... Since the E field lines point left, then the force on a positive test charge will be to the left and the shaded area charge must be attracting the positive test charge. That makes the shaded area negative. Note that even though we will later ask questions about the Neg “on” charge, we have not at al ...
