Things needed for the experiment:
1) A web camera.
2) A glass platform
3) A hovering device.
4) A program that can take chrono-photographs through the webcam.
The Procedure:
1) Place the hovering device in such a way that it stays at rest i.e. with a net force equal to null vector.
2) Push the device and take a chonophotograph.
In the chronophotograph, the gap between each consecutive photo was 0.1 sec. Here's a diagram of how the chonophotograph looked.
Observation:
As we see in the chronophotograph, the gap between every two points is the same. In other words, the distance traveled by the hovering device is the same for every 0.1 sec.
The hovering device's motion was thus a motion with constant velocity.
First of all, how is the motion of a hovering device friction-less?
The hovering device has a motor that pushes it away from the surface thus compensates for the weight of the object.
There is thus no friction between the hovercraft and the surface and its motion is frictionless.
We know that the net force on the hovering device is Zero, According to Newtons's First Law , if the net force acting on an object is zero, the object will maintain its state of motion (at constant velocity). The chronophotograph proved the fast that the velocity was constant:
Conclusion of the first experiment:
The motion of a hovering device which is a friction-less motion is with a constant velocity (i.e. a uniform rectilinear motion).
An alternative to the hovering device experiment is a balloon hovercraft:
Things we need to make a balloon hovercraft:
-A CD
-Some blue tag or a sealing tag
-A balloon
-A bottle cap
Procedure:
Take the CD and fix the bottle cap at its center with the blue tag. Attach the balloon to the cap and inflate it. Thats it! Its a perfect substitute for a hovering Device
