Teaching Instrument Flat Throwing Motion Experimenter Model Physical Mechanics Model Physical Mechanics and Motion Experimental Equipment

Plane Parabolic Motion Experiment:1. Rotate the small knob, move the support shaft of the ball groove, and place it at any position above the panel. (The position should take the upper position first and move down one by one)2. Put the white paper and carbon paper on top of each other (the carbon paper is outside) flat on the panel, and press the top and bottom with magnetic strips. Note that the main position of the paper should be based on the squares on the panel (ie the left and upper edges of the paper) and the throwing point of the flat throw rail as the origin 03. Adjust the position of the height adjuster and fix it well. Use a clip to push the steel ball against the adjuster to release the steel ball. The steel ball hits the ball receiving groove and leaves marks on the white paper through carbon paper.4. Lower the ball receiving slot one by one and repeat the above operation, that is, trace a series of steel ball movement traces on the white paper.5..Remove the white paper,. Draw a horizontal line at the origin, the X axis to the right and the Y axis vertically downward, and connect the recorded points with a smooth curve to draw the level of the steel ball.Throwing trajectory.6. Measure the height h and the horizontal distance S of each point, and use the formula to find the horizontal speed of the steel ball, that is, the initial speed V of the steel ball in the horizontal throwing motion, and finally calculate the average value.

• The instrument can accurately describe the trajectory of the motion of the paraboloid, and measure the initial velocity of the paraboloid. The structure of the instrument is simple and the operation is convenient, which is beneficial for students to experiment in groups.
• The instrument is supported by the flat throwing rail (to hold the flat throwing ball, and the position and height of the flat throwing ball can be adjusted.
• And throw the ball horizontally), catch the ball (catch the flat throw ball, and make the ball automatically trace the trace point);
• Heavy hammer (adjust the experimental device to reach the horizontal position) leveling bolts (adjustment of four leveling bolts, cooperate with the heavy hammer to reach the horizontal position); steel balls, magnetic strips, panels, bases, etc.
• Fix the flat throwing guide rail to the front position of the panel with screws, and the horizontal part of the end of the guide rail is required to be perpendicular to the weight line.
