The Effects on a Ball Rolling Down a Ramp

Influence of the ball on the roll-off slope Purpose: I am trying to find a factor influencing the rolling distance of the ball when the ball is released from the top of the slope. Variable Input / Control Result Unit Ground Ball Height Distance Ball Height Distance Ball Rolling Centimeter (cm) Slope Speed ​​Ball Roller Bevel Direction Ball Rolling Surface Floor Surface Marble Size Marble Size Variable: Height Lamp is the ball rolling speed Because the higher the lamp that changes the distance the higher the ball.

Influence of the ball on the roll-off slope Purpose: I am trying to find a factor influencing the rolling distance of the ball when the ball is released from the top of the slope. - The rolling bearing in the motor supports and positions the rotor, maintains a small and constant air gap between the rotor and the stator, and transmits the load from the shaft to the motor frame. By using bearings suitable for the application, it is possible to operate the motor efficiently over the design speed range, minimizing friction and power loss, and realizing low noise and long life. On the other hand, if the motor is not properly used, the bearing will be damaged rapidly.

In the first episode of episode 1, a prospective teacher performs a simple experiment of confirming the movement of the bowling ball in the corridor. As the ball rolls, team members use their meters and stopwatches to track their position. At a given moment, the member associates the measured position with an acceptable starting point. Stephen: I explained the chair and lamp settings and how the bowling is 30 cm above the lamp. Stephen: When I first started, I started a timer from where the ball first touched the ground. We were lined in the hall there. At the arbitrary time like 200 cm, the timer starts and the timer stops saying "stop". We repeated this many times. We took every distance ... So we made 200 cm ... Every time we separate ...

What is mathematical modeling? Exploring future teachers uses experiments to link mathematics to sports research

Roll each ball many times along the ramp and record the distance traveled from the bottom of the lamp. A more reliable result can be obtained by performing measurement more than three times for each. Measured values ​​are measured as precisely as possible, but by repeating each test multiple times, the effect of errors can be minimized. For each ball, individual measurements are added and divided by the number of measurements to obtain the average. Perform this process for each ball and record the rule in the notebook
