In moving process, the end of rotor plate 6 can put down rotor plate 6 between two raised strips 24, now rotor plate 6
One end can with against raised strip 24 because the distance between raised strip 24 differs 1cm or 2cm, the height of raised strip 24
Degree is certain, and the length of rotor plate 6 is also certain, so the angle of rotor plate 6 is basic it was determined that there is some examination question meetings
Some changes are carried out on existing experiment basis, for example dolly 2 is moved on the base 1 of certain angle, and some are learned
Raw is simply that the description imagination does not come out according to examination question, so we can change device according to the description of examination question, accords with device
The description of examination question is closed, allows students to see the experiment content of examination question, more convenient student is understood.
In existing examination examination question, acceleration test examination question can be improved, be tested sometimes using photoelectric door,
Exactly the time used in the unit distance of dolly 2 can be obtained by experiment, to carry out the calculating of acceleration, photoelectric door passes through dolly
Anti-dazzling screen 19 in 2 determines the elapsed time of dolly 2.
In existing examination question, often outlet is inscribed to the force analysis of mobile object, so to disposing stress on dolly 2
Apparatus for demonstrating, dolly 2 is placed on rotor plate 6, allows student to carry out force analysis, then adjusted pointer 20 and carry out trolley for demonstrating 2
Stressing conditions because pointer 20 can the bottom affected by gravity, we, which are fixed pointer 20 using standing valve 21, makes
Classmates are readily appreciated that and then can answer examination question.
