## Comparing The Spring Constant And The Velocity Of A Duck

- 1424 Words
- 6 Pages

The purpose of the lab was to find the spring constant and the velocity of the duck when it launched. The spring constant is the ratio of the force that the spring applies over a given distance and the velocity is the speed and direction of the duck. To find the spring constant we used the work-energy theorem. It states that the work done by an object is the sum of all forces acting on an object which is equal to the change in the object’s kinetic energy. The equation is mgh + .5kx2 + WNC = mgh + .5mv2. This equation works because energy is conserved. We also used Δx= .5at2+vit, which is used to find the time and velocity of the duck. Then we use .5kx2=.5mv2, which comes from the work-energy theorem. In this experiment, the velocity and the

## Spring Constant Lab

The purpose of the lab is to collect data, then from the data determine the potential energy, spring constant, and the maximum velocity of the toy. The toy measured to be 0.055 kg, 0.06 m tall when standing and 0.04 m tall when pressed down. During the experiment, we determined that the average maximum height of the toy is 0.622 m. From this information, we determined, using the equation PE=mgh, that the potential energy of the toy was 0.313 Joules. Then, using the potential energy and the difference between the toy’s height when it's pressed down and when it's freely standing we determined the spring constant by using the equation PE=(1/2)kx^2.

## An Analysis of Vibration

- 2299 Words
- 9 Pages

An oscillating motion of a particle or body about a reference point which is fixed is known as vibration. This motion is sinusoidal i.e., simple harmonic or otherwise non sinusoidal i.e., complex. This can occur in different modes as translational or bending modes and, since the vibration can occur in more modes at a time, vibration analysis is very much difficult.

## Non Linear Behaviour And Chaos

The Duffing Oscillator named by the German electrical engineer Georg Duffing is a non-linear, second-order differential equation, periodically forced and includes a damping term proportional to particle’s velocity. The equation can show different types of oscillations such as a limit cycles and chaos. Given its characteristics Duffing oscillators are often used to produce similar behaviours in nature. The equation in this experiment has been studied through the dynamics of a particle under a potential field, driven by an applied periodical force. The equation of motion for the particle in this system is
