If the ball is falling, then work is being done.
Work is the product of (force) times (distance). The ball in the air has force acting on it, created by gravity, and known as the "weight" of the ball. If the ball is falling, then the work done on it by gravity is (its weight) multiplied by (the distance it falls).
If the ball is accelerating up, then something has to be providing force greater than its weight, in order to lift it against the force of gravity. It may be a muscle, a motor, an elevator, or some kind of air-foil taking energy out of wind. The work done on the ball is (the upward force on it) multiplied by (the distance it's lifted).
If the ball is moving only horizontally, and not the slightest bit up or down, then almost no work is being done, since there's no significant horizontal force acting on it. The ball does a small amount of work to move air as it moves through the atmosphere.
What else can I help you with?
Is the pitcher still doing work on the ball as it flies through the air?
No, once the pitcher releases the ball, their work is done and the ball's trajectory is determined by the laws of physics such as gravity, air resistance, and spin. The pitcher's influence ends upon release.
When air resistance is a factor affectin the ball will return to original with same less or more ke?
When air resistance is a factor, the ball will return to its original point with less kinetic energy due to the work done against the resistance of the air. The air resistance converts some of the ball's kinetic energy into thermal energy, causing a reduction in the ball's speed.
Is work being done by an automobile operating for several minutes?
No work is being done by the automobile if it is standing still with the engine running since it isn't in motion (not counting any work done by the vibrations transmitted to the air and ground upon which it rests). The engine, on the other hand IS doing work while idling since the parts inside are moving and both having work done on them and, in turn, performing work on other parts.
Is air resistance in a ball being thrown?
Yes, air resistance affects a ball being thrown by creating a force that opposes its motion through the air. This force acts to slow down the ball and alter its trajectory, especially at higher speeds or in the presence of turbulent air flow.
Who air pollution being done to?
everyone
A ball with a weight of 30 newtons is kicked 2 meters into the air what work has been done?
w=(f)(d) 30 times 2 =60
How is air pollution being done?
Greatest cause being man
What was the piece work done at home?
air condition
What creates pressure in a bicycle tire?
The pressure increases, and the molecules collide with the tire's inner surface.
Does it take time for the air get colder if you have replaced the air compressor?
If the work was done correctly, no.
Why does a ball bounce higher than others?
it will bounce higher if there is more air. ex. Flat basketball- being flat, the ball will just hit the floor and will be pressed inwards on the spot it landed pumped basketball- being full of air, the ball hits the ground and like a flat basketball is pressed inwards. but because there's air in it, the air will make the ball retain its shape and bounce.
When a pitcher is holding a baseball the ball has energy. After the pitcher throws the ball the ball has energy.?
The Ball has energy in the form of potential energy as if it was released it would fall to the ground. The pitcher uses chemical energy to move his arm and give momentum to the ball. The ball's energy is now transformed to kinetic energy as it moves through the air.
