I don't know whether this really is the case. But if it is, I can imagine the moving magnet inducing currents in the pipe, resulting in movement energy being lost. (The currents will induce a magnetic field that opposes the movement.)
The ball has both potential energy when it is thrown upward (due to its position) and kinetic energy when it falls (due to its motion). As it falls, potential energy is converted into kinetic energy.
This is called electromagnetic induction, where a magnet or coil of wire moving relative to each other induces a flow of current in the wire. This process is used in devices like generators to convert mechanical energy into electrical energy.
To have zero speed at the top, you need to throw the projectile with an initial velocity such that it reaches its maximum height at that point. This requires the initial velocity to be exactly equal to the velocity that would be attained due to gravity when the projectile falls from that height. The angle of projection should be such that the vertical component of the initial velocity cancels out the velocity due to gravity.
Yes, a magnet can be ridden of it's magnetic properties by either using it to pick up iron filings or heating it up and rubbing it on another magnet. This is called demagnetizing. On the other hand, magnets can be re-magnetized by heating and holding the south end of a magnet on one end and the north side of another magnet on the opposite end although the magnet will not be as strong as before.
When you throw a ball in the air and catch it, the initial energy transformation is from mechanical energy (kinetic) to potential energy (gravitational potential). When the ball falls back down, the potential energy is converted back to kinetic energy.
The leaf does not fall straight down. It falls slowly because of air resistance. The air provides upward force. The upward force on the apple is negligible.
Throw the magnet at the TV REALLY REALLY HARD.
anywhere where you could throw away aluminum cans
The Kaiser Aluminum Hour - 1956 Throw Me a Rope 1-15 was released on: USA: 29 January 1957
It flows through aluminum foil better because electricity flows throw aluminum or metal better then plastic or other
you throw stuff at him when he falls over pick him up and throw him
lob
falls apart
Stop immediately & throw them a life preserver.
Yes, in Falling for the Falls part 2.
The egg has to stay together while it falls so the best method is to use straw and aluminum foil place it inside the helmet and tape it. On top you have to put something as well otherwise the egg falls out. In this case you place some hard paper on the top and make an opening so the egg can get in. Like this The egg is safe and will resist in every case you throw it down.
You find a paper clip in the sports shop under the couch first then you go to the magnet use your rench in your spy phone open the box beside the magnet and throw the paper clip in. This makes the box blow up and the magnet dies.
