Lecture 17 - De Anza College
... Galileo predicted (correctly) that all objects at the Earth’s surface accelerate at the same rate, g . This was a revolutionary idea because it seems obvious that less massive objects should fall more slowly: consider a feather and a bowling ball. What is happening there? ...

... of equation of motion. As a result we will diminish the number of equations describing the motion of an object in question. 10. If there are several bodies in the problem, repeat all steps described above for each object separately. If cables connect these objects, apply 3rd Newton’s Law for tension ...

(2.5 points) Only if a force on a particle is conservative: A) does it obey Newton's third law B) does it obey Newton's second law C) does it do no work when the particle moves exactly once around any closed path D) it is not a frictional force E) does the work it does equal the change in the ki ...

... 1. Hang the object by one point and draw a vertical line following a plum-bob. 2. Hang the object by another point and do the same. 3. The point where the two lines meet is the CM. Since a rigid object can be considered as collection of small masses, one can see the total gravitational force exerted ...

When the light turns green, the cars accelerate to the right (Fig. 2). To achieve this acceleration, the car tires exert a backward force on the road (to the ...

4.1 The Concepts of Force and Mass
... Version 1 A force is conservative when the work it does on a moving object is independent of the path between the object’s initial and final positions. Version 2 A force is conservative when it does no work on an object moving around a closed path, starting and finishing at the same point. ...

It is connected by a lightweight cord, which passes over a massless and frictionless pulley, to a second box B, which hangs freely as shown. (a) If the coefficient of static fr ...

... Example. Two automobiles of equal mass approach an intersection. One vehicle is traveling with velocity 13.0 m/s toward the east and the other is traveling north with speed v2i. Neither driver sees the other. The vehicles collide in the intersection and stick together, leaving parallel skid marks at ...
