describe the physical difference between elastic and inelastic collisions. in an elastic collision all kinetic energy of the bodies colliding before the collision remains after the collision and none is converted into noise‚ or any other form of energy. in the real everyday world all collisions are inelastic and it is merely a matter of extent. 2. How are you able to determine if conservation of momentum occurs in each collision? momentum is always conserved. but you can calculate the vector sum

Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this

Purpose: To practice direct and indirect measurement Introduction: Do you think you could measure the average thickness of a sample of M&Ms without directly measuring selected M&Ms? The answer is "yes‚" and in this activity you will make direct and indirect measurements of the thickness of M&Ms. You will compare the results and evaluate the reliability of each method of measurement. Be sure to view the tutorial on the proper use of the vernier caliper. Please re-visit the information on when

Motion of the Cars In this part of the experiment‚ we are trying to figure out how fast each of the cars are moving using our own measurements. We are also asked to make a mathematical equation that describes the motion. What we plan to do is use 2 meter long meter stick to measure the distance of the cars and record the position at each time interval. After that an average velocity can be found. After we used the average velocity‚ we were able to put it into the equation of a line formula and

Torque and Equilibrium Purpose: Apply principle of static equilibrium to determine a coefficient of friction. Research Question: What is the coefficient of friction between a meter stick and wall? Hypothesis: Tying a piece of string on to the end of a meter stick‚ put the other end of the meter stick against the wall so that the meter stick is horizontal and does not slide down the wall. Hang a weight on the meter stick sliding it to a point where the meter stick is about to come off from

properties about the incident light‚ in particular its wavelength. This will be our task‚ in this first optics lab exercise. The analysis of diffraction patterns is used extensively in the sciences to provide information about the microscopic structure of molecules‚ atoms‚ and nuclei. In addition to various forms of light (gamma rays‚ x-rays‚ visible light‚ infra-red‚ radio waves)‚ even high-energy atomic and sub-atomic particles (electrons‚ protons‚ and neutrons) can be used in diffraction studies.
