The materials needed for this experiment will be a ball, a meter long ramp, tape, a protractor, and stopwatch. For the first step you will set up the incline of the ramp at a 10° angle. Then you will mark, with tape, six points on the one meter ramp that are equidistant from one another. Next, using a stopwatch, you will roll the ball from each point three times each. After all the trials are completed for the six distances, find the average time it took the ball to reach the end from each point.
Centrifugal Force - Is the apparent force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body. 8. Centripetal Force - Is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body, toward the fixed point of the instantaneous center of curvature of the path. 9.
Jessica Yan Rick St. Denis, Tyler Wiseman 13 September 2012 Projectile Motion: Ball in the Bin Purpose: The purpose of the experiment is to determine the velocity of a ball launched from the Projectile Launcher device, and then to use that velocity to find where on the floor the ball will land given a specific angle. Theory: Two-dimensional motion is as it sounds, made of the two components of Vertical velocity and Horizontal Velocity. Horizontal Motion can be described as constant, neglecting air resistance, and Vertical Motion is characterized by the acceleration of gravity pulling at 9.8m/s². In this particular experiment, the total velocity will be split into the two components in order to find the time in the air, and horizontal distance from the launcher. The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit.
Forces Test Review 1. Inertia can be best described as the (A) force that keeps an object in motion with constant velocity (B) force that keeps an object at rest (C) force that overcomes friction (D) property responsible for an object's resistance to changes in motion (E) property responsible for slowing down an object 2. A box is given a sudden push up a ramp. Friction between the box and the ramp is not negligible. Which of the following diagrams best represents the directions of the actual forces acting on the box as it moves upward after the push?
What you are looking for is how it rides. You want to start by checking the servo and speed controller. You want to make sure the wheels turn and that you can go forward and reverse. You can check the suspension and handling by making some sharp turns and going over bumps and small jumps. Next you want to see how it runs at high speeds.
Abstract To determine the coefficient of restitution, the method used will involve recording the height from which a squash ball is dropped and the height with which it bounces up to and then comparing the ratio of the two heights. The temperature will be adjusted by using a water bath heated up to 100°C and then allowing the temperature to fall and recording results as necessary. Using a high definition digital camera to record the height at which the balls bounce against a marked background of 1cm lines. The bounce height recorded by the camera is then divided by the standard initial height of 1.2m to produce e2. This value is then square rooted to provide a value for the coefficient of restitution.
10 drops of each cation that are left are added to clean centrifuge tubes. 15M NH4OH was added dropwise until a color change or a precipitate was formed with no more than 20 drops added. A cation should be eliminated. If the solution formed a precipitate before, then 10 more drops of the 15M NH4OH was added to the solution. The last two cations should be separated with the observations of the additional NH4OH added.
G. TRUE or FALSE: The acceleration of a particle following a space curve lies in the normal plane. 2) Sketch the curve with the given vector equation, starting at t=0 . Indicate with an arrow the direction in which t increases. Be sure to include a few points to justify your graph. 8pts r(t) = cos t, sin t, sin
Set the stopwatch to 1 minute. Use a lighter to light the fuel. Blow out the fire when the timer reaches 1 minute. Measure the final temperature of the water using a thermometer. Then measure the final mass of the fuel using a mass scale.
Suggest two reasons for this change. Task 2 Press back but not clear and change the number of chips to 10 but leave the acid concentration at 1.0 mol/dm3 . Click start and take readings approximately every 3 seconds (by clicking the take readings button) until the mass reaches 0.0 g. Stop the reaction immediately. Plot these results on the same grid as the results of your first experiment. How does the rate of reaction in Task 2 compare with the rate in Task 1?
