S74 Experimental Investigation Determining Acceleration in relativity to force and mass Reece Day Izaac Ellings/Lachlan Morgan 26/08/2013 Mr Fogarty 1. Introduction Background theory review Physics is defined as the study of matter and energy as well as their interactions (Lombardi‚ 2001). Although physics is more theoretical based‚ countless solutions are discovered through observation/experimentation (Physics.org‚ ?) and many seemingly intricate things in nature can

observed since the carts stuck together after the collision‚ creating friction that converted the lost energy into heat. Objective The objective of the lab was to investigate the validity of the laws of conservation of momentum and energy by analyzing simple elastic and inelastic collisions. Procedure EQUIPMENT: -horizontal dynamics track -collision and dynamics carts with picket fences -photogates connected to the Science Workshop interface -250 g weight Two carts were weighed and

(mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an object has a speed and direction. Using the formula “(ma * vai) + (mb * vbi) = (ma* vaf) + (mb * vbf‚)” the final velocity of two carts after they collide can be found. The first cart is 1.5 kg traveling at 0.7 m/s and the cart that it collides with is 1 kg and at rest‚ so (1.5 kg * 0.7 m/s) +(1 kg * 0)= (1.5 kg * vf) + (1 * vf). 1.05=2.5 (vf) so the final velocity is 2.38 m/s. This collision would look like:

Introduction The purpose of this experiment is to determine whether a change in mass affects the acceleration of the cart. The independent variable is the mass of the weight and the dependant variable is the acceleration. I do not think there is a control in the experiment because we do not know an absolute result with any of the masses of the weight. Besides‚ if we used 0g as our control‚ the cart won’t even move. Hypothesis Under these conditions I believe that the results shown in the distance vs.

Analyzing Exploding Carts - Lab Activity Objectives We will study the relationship of force and the duration of the collision. In doing so we will observe the max force experienced by an accelerating cart when it impacts another cart with a spring. A stiff spring will be used. We will collect the information through two items. We will use distance and time as information collectors. This will measure the acceleration‚ velocity‚ and position of the cart as it moves down the track. The most

in the cart by measuring the force required to compress a spring as well as the distance the spring compressed relative to the equilibrium position. A cart was placed onto a slanted track and speed and force censors were used to record appropriate data. The spring constant was determined by substituting the measured data into Hooke ’s Law (Fs=-kx). This gave a spring constant of 597± 28.5 Nm-1. A secondary experiment was also conducted to prove conservation of energy. A spring on the cart was compressed

The application also provides a drag and drop feature so that a user can add a product to the shopping cart by dragging the item in to the shopping cart. The main emphasis lies in providing a userfriendly search engine for effectively showing the desired results and its drag and drop behavior. .
