Acceleration
... Theory that explains how chemical reactions take place and why rates of reaction alter. For a reaction to occur the reactant particles must collide. Only a certain fraction of the total collisions cause chemical change; these are called successful collisions. The successful collisions have sufficien ...

HP Unit 2 vectors & newton 1D - student handout
... A person stands on a bathroom scale in an elevator at rest on the ground floor of a building. The scale reads 836N. As the elevator begins to move upward, the scale reading briefly increases to 935N but then returns to 836N after reaching a constant speed. a) Determine the acceleration of the elevat ...

... What supplies the force to an object in circular motion? What pays the force bill? The answer to this question varies: • For Odie, the centripetal force is provided by tension in the string (the tension transmitted in the string is provided by the hand of the person swinging Odie in circular motion) ...

Version A
... 5) Can an object's velocity change direction when its acceleration is constant? A. No, this is not possible because it is always speeding up. B. No, this is not possible because it is always speeding up or always slowing down, but it can never turn around. C. Yes, this is possible, and a rock thrown ...
