Technical field
The utility model belongs to physical demonstrator technical field, and in particular to a kind of physics dynamic Overweight and Zero Gravity demonstration device.
Background technology
Overweight is restraint suffered by object, also referred to as elastic force（Pulling force or holding power）More than showing for gravity suffered by object
As.When object does accelerated motion upwards or retarded motion downwards, object is in overweight state, i.e., no matter how object is transported
Dynamic, as long as with acceleration upwards, object is at overweight state.In fact, as long as object has straight up relative to the earth
Acceleration when, overweight phenomenon will be produced；Otherwise can then produce weightlessness.It should be pointed out that no matter object is gone back in overweight
It is state of weightlessness, the earth acts on the gravity of object to be present all the time, and size does not also change, and simply object is to holder
Pressure (or the pulling force to hanger) there occurs change, it appears that as the weight of object has increased or reduces.Object is drawing
There is quality in the field of force during free movement and do not show weight or a kind of less state of weight, also known as zero-g.Weightless sometimes general
Nulling gravity and microgravity environment.Specifically, when acceleration straight down when be state of weightlessness.Pressure of the object to holder
（Or the pulling force to hanger）It is referred to as weightlessness less than the phenomenon of gravity suffered by object.Overweight, weightless is senior middle school physics teaching
Difficult point, and the now important phenomenon in science and technology of aviation, but the multiplex deformation of existing physics dynamic Overweight and Zero Gravity demonstration device
Carry out qualitative demonstration, its accuracy is relatively low and very big with the life feeling difference of student, effect is very bad, without convincingness, because
We need a new physics dynamic Overweight and Zero Gravity demonstration device for this, meet the demand of people.
