Hovercraft Blog Post

Riding the hovercraft felt a bit weird and cool at the same time. It is definitely a great experience but the concept of it moving without any forces acting on it is pretty nice, for the people that have not tried it yet, you are up for a surprise. Its different than riding on a sledge or skateboarding as you are hovering, so you move without any forces acting on you while not touching the ground. 

From this experiment i managed to learn that it is possible for an object to be moving without any forces being acting on it, this refers to newtons first law which states, An object in motion or at rest stays in rest or in motion unless acted on by an outside force. So the hovercraft kept moving as it was moving in the first place and there are no forces affecting it. 

Acceleration always depends on forces affecting a certain object, so if the net force of an object is not 0 then there is an acceleration going on. Which occurred at the push and stopping parts of the hovercraft experiment. 

Constant velocity is when an object is moving at a constant speed in a certain direction. Relating it to our experiment, after the person on the hovercraft was pushed, there wasn't any forces acting on the object (Net force = 0) so it moved at constant velocity (equilibrium) until it reached the stopping point the force of the person stopping it made it stop. 

Some members were harder to stop than others as they weighed more, so you had to put in the same effort to move them (push them) and to stop them, so because they weigh more the amount of force you have to put it to start and stop them is much more.
