Force and acceleration Chapter_3_Lesson_1
... Mass and Acceleration • If you throw a softball and a baseball as hard as you can, why don’t they have the same speed? • The difference is due to their masses. • If it takes the same amount of time to throw both balls, the softball would have less. • Force, mass, acceleration and acceleration are r ...

Practice test 2, hints Question 1: Magnetic field lines always form
... Question 9: The proton and the positron have the same charge and they are in the same field, so they experience the same force, F = qE. The acceleration is a = F/m, so the lighter particle (the positron) has the greater acceleration. When the particles reach the other plate, the potential energy U ...

... Begin by choosing the positive direction as down. That seems reasonable since the fire fighter will slide down the pole and not up the pole. The two forces on the fire fighter are his weight, W=mg, which acts downward, the force of sliding friction, f, which acts upward ( ie the friction force oppos ...

... 4-34 A factory worker pushes horizontally on a 250 N crate with a force of 75 N on a horizontal rough floor. A 135 N crate rests on top of the one being pushed and moves along with it. Make a free-body diagram of each crate if the friction force is less than the worker’s push. There is a friction fo ...
