please answer the following questions so I can understand, thank
you very much!
A mass, m, is attached to a massless string of length l; the other end of the string is attached to a rigid and frictionless support. While keeping the string taut, the mass is raised to a height h (see diagram) and released. Under the force of gravity (g = 9.8 m/s), the motion of the mass follows the dashed line (i.e., it's a pendulum). (a) Draw...

A simple pendulum is a mass on a string. Does the period with which the pendulum swings depend on mass, length, initial angle, or some combination of those? In this lab, you will vary each of these three parameters independently and measure the affect they have on period. Using graphical analysis techniques, you will determine the functional dependence of period on each of those quantities. Not knowing how any of these quantities—length l, mass m, and initial angle (theta)—affect the...

4 Exercise 4. In any mechanics problem where the mass m is constant, the position vector F sweeps out equal areas in equal times the magnitude of the angular momentum ILI is conserved (Note: be sure to prove "if and only if") (Note: don't try to use Exercise 2 in the proof of...

Torque and Angular Acceleration Learning Goal: To understand and apply the formula τ= Iα to rigid objects rotating about a fixed axis. To find the acceleration a of a particle of mass m, we use Newton's second law. Fnet =ma, where Fnet is the net force acting on the particle. To find the angular acceleration a of a rigid object rotating about a fixed axis, we can use a similar formula: Tnet = Ia, where Tnet=∑T is the net torque acting on the object...

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...

[1] CONSIDER THESE TWO Cases : 1. A ball moves in uniform circular motion. (i) Sketch a two dimensional position plot of the functions x(t) and y(t). Extra credit: What type of plot is this? (5 points). (ii) On your plot, draw in five different velocity vectors at different times. (iii) Is there an acceleration ? Why or why not? 2. A ball moves in a straight line while its speed decreases. (i)...
