The work-energy theorem applies to changes in kinetic energy because.... a- forces applied over a distance change the position, therefore the object has some velocity, which implies kinetic energy. b- forces applied over a distance change the position, therefore the object has some acceleration, which implies kinetic energy. c- forces are a part of kinetic energy. d- forces applied over a distance change nothing about the system so we have to study kinetic energy.

1. The graph shows the motion of an object traveling in a straight line as a function of time. What is the average speed of the object during the first two seconds? 5 m/s 2.5 m/s 10 m/s 20 m/s 2. Using the velocity versus time graph, what was the average acceleration of the object during segment B? 0 m/s/s 20 ms/s 10 m/s/s 5 m/s/s 3. Remember to identify all your data, write the equation, and show your work....

Vibrational Motion Introduction If an object is following Hooke’s Law, then Fnet = -kx = ma Since acceleration is the second derivative of position with respect to time, the relationship can be written as the differential equation: kx = m δ2xδt2/{"version":"1.1","math":"<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>k</mi><mi>x</mi><mo> </mo><mo>=</mo><mo> </mo><mi>m</mi><mo> </mo><mfrac bevelled="true"><mrow><msup><mi>δ</mi><mn>2</mn></msup><mi>x</mi></mrow><mrow><mi>δ</mi><msup><mi>t</mi><mn>2</mn></msup></mrow></mfrac></math>"} Methods for solving differential equations are beyond the scope of this course; in fact, a class in differential equations is usually a requirement for a degree in engineering or physics. However, the solution to this particular differential...

5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...
