PHYS 2207 Prelim #2 Exam Questions And Answers 100% Verified. Rotational analogs of all kinematics - answerjust remember can use any of the kinematic equations with the angular quantities as you would use them with linear quantities how many revolutions in that time - answerbe sure to use the kinematic equation involving change in angle and then divide that by 2pi to get revolutions from radians; if you give a final frequency/speed that is not constant likely for these prelim's problems!...

Jacobian How to use the chain rule? When you have a composition of functions (dw/ds, dw/dt)= (df/du, df/dv)(du/ds, dv/ds, du/dt, dv/dt) so it gives a vector Classify critical points 1. differentiate WRT each variable x and y. 2. set them equal to 0. then solve for the values (often take the equation that is easy to factorize and take its values. 3. replace the values obtained in the other partial equation set equal to 0 to get the points ***trick: you can add the equations some...

AP Physics Unit 3 progress check Parts A&B (answered_2023.) AP Physics: Unit 3 Progress Check: MCQ Part A Planet X has a mass of MM and a radius of RR. Planet Y has a mass of 3M3M and a radius of 3R3R. Identical satellites orbit both planets at a distance RR above their surfaces, as shown above. The planets are separated by such a large distance that the gravitational forces between them are negligible. How does the magnitude of the gravitational force FYFY exerted by Planet Y on its sa...

What two entities comprise a vector? Magnitude and direction What do you do with any vector that is not on either the x or y axis? Break it up into x and y components using trig, add up the components. 00:11 01:23 How are velocity and speed different? Velocity has a direction and speed does not have direction. What quantity is calculated from slope of the displacement versus time graph? velocity What does upward slope on a displacement versus time graph ...

WGU C451 Module 2: Forces, Energy, and Motion Questions and Answers Rated A+ What is potential energy? Stored energy that has the potential to do work. How does a change in mass of an object affect the gravitational potential energy of that object? How does a change in height affect it? The greater the mass, the greater the force of gravity it exerts, so the more attracted to each other they will be. When objects are pulled further apart, the force of gravity weakens. The distance increases the...
