Tasneen Ahsan Date: 19th November‚ 2012 Purpose To show how the acceleration of an object changes when‚ the mass changes and the net force is kept constant and when the mass is the same.. Hypothesis I predict that by changing the mass of the object will result in a change in the acceleration as Newton`s second law states that the magnitude of the acceleration of any object is directly proportional to the magnitude of the net force‚ and inversely proportional

If the car takes 2s to stop after the application of brakes‚ calculate the distance it travels during this time. 5. What is positive acceleration and negative acceleration? 6. Why is the motion of Satellites around their planets considered an accelerated motion? 7. Study the time (t) versus distance

Acceleration Velocity Displacement Distance Time Definition 1. Acceleration is the rate of change of velocity with time. Velocity is a vector physical quantity; both magnitude and direction are required to define it. the length of an imaginary straight path‚ typically distinct from the path actually travelled by P. Distance is a numerical description of how far apart objects are. In physics or everyday usage‚ distance may refer to a physical length‚ or an estimation Time in physics is

first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the second experiment‚ acceleration of a cart traveling down a slight incline was measured with a two photogate method. Gravity was calculated and yielded

Sub-outcome 3: Derive units of speed‚ acceleration‚ force‚ density‚ area‚ volume from basic units. The Derived Units: From the base SI units‚ many units for other physical quantities were derived. A derived unit is a unit that is defined by a simple combination of one or more of base units

Based on these measurements‚ the acceleration of the blood ejected by the heart can be determined. Patients with low blood accelerations generally have weakened heart muscles. A sketch of a single cycle of a ballistocardiogram is given in the figure. . The units of the graph are arbitrary and linear for both time‚ ‚ and acceleration‚ . Part A At what time (in the arbitrary

PROCESSING THE DATA (PART A) 1. Describe the difference between the two lines on your graph made in Step 6. Explain why the lines are different. Referring to graph on the right the difference between the two lines is that one line is at a faster speed than the other in the same amount of time. While one is steeper the other one is not as steep. 2. How would the graph change if you walked toward the Motion Detector rather than away from it? Test your answer using the Motion Detector. Since

LAB WRITE-UP NAME: Gabriel-Ohanu Emmanuel PARTNER: Baptiste Gilman TITLE: Graph Matching PURPOSE: The purpose of the experiment was to analyze the motion of a student walking along a straight line in front of the motion detector moving back and forward with different speed trying to match the graph provided. To also understand and interpret graphs of distance vs time and velocity vs time. To also know what the slopes of the each graph represent which tells how far the student travelled
