The apple falling down indicates that there is some kind of gravitational pull.
A spoon is magnetic !
The spring in the diving board is what causes an elastic force to occur. Once the swimmer jumps up into the air, the board retracts causing the spring to compress and then go back to its original form
lets see how much force it takes to move this chair
The magnet will attract anything object with magnetic materials. If the object is not magnet such a piece of wood, the magnet will not attract towards it.
It did not take a lot of effort to push it because the surface is flat
The spoon got attracted to the magnet because it is made out of steel. Steel is a material that is magnetic therefore, any objects made out of steel will be magnetic. The force of the magnet will increase once there is a higher rate of magnetic materials in the objects.
Starting at point A, when the chair is being pushed across a flat surface it causes sliding friction due to force that the chair has been given.
During the sliding friction process, the chair is being accelerated forward while the friction force is pushing back the opposite way against the applied force and acceleration. The friction force becomes outweigh by the applied force.
