In physics, work is defined as the transfer of energy to an object by applying a force through a distance. When dropping a ball, gravity is the force acting on the ball, but no energy is transferred by an external force so technically dropping a ball is not considered as doing work in the physics sense.
What else can I help you with?
Is work done when you throw a ball?
Yes, work is done when you throw a ball. When you exert force on the ball to throw it, you are transferring energy to the ball, thus doing work on it. This work results in the ball gaining kinetic energy as it moves.
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.
If the sum of all the forces on a ball is zero what is the ball doing?
I don't know the answer.thats why I went to this website.💩💩
Is energy is capacity to do work?
Energy is the capacity to do work.
What is the connection between balls dropping and voice breaking?
The dropping of balls and voice breaking both involve sudden changes in pitch. In the case of balls dropping, the pitch changes as the ball accelerates towards the ground. In the case of voice breaking during puberty, the pitch changes as the vocal cords grow and thicken, causing fluctuations in the voice.
Is the ball dropping next year?
You're ball is also dropping.
Why funnel is used for dropping the ball bearings?
Why funnel is used for dropping the ball bearing
How would the motion of a ball being dropped be viewed differently as seen by the person dropping the ball and a stationary observer?
If the ball were simply dropped, the person dropping the ball and a stationary observer should see the same thing.
Is work done on a ball when a pitcher throws it is the pitcher stil doing work on the ball?
Well, that's a tough question. I suppose it all depends on how you look at "work." Obviously when the pitcher releases the ball, his work is finished, but the effect that he places on the thrown ball is not finished until the ball stops. The pitcher has transferred his "work" energy to the ball. The ball then carries out the remainder of his work.
Is work done when you throw a ball?
Yes, work is done when you throw a ball. When you exert force on the ball to throw it, you are transferring energy to the ball, thus doing work on it. This work results in the ball gaining kinetic energy as it moves.
How is force being used when dropping a ball?
Gravity
Energy is the ability to work?
Yes. No work occurs until an object is moved. When you throw a ball, the ball isn't doing work. It has potential and kinetic energy while moving. Once it hits something and moves it, the ball has done work.True.
Why do you need to use balls for dropping ball experiment?
you don't
When a punter kicks a football is he doing work on the ball while his toe is in contact with it?
yes!
What do you mean by positive and negative work?
Positive work is input energy, w= -f.d - |fd|cos(fd) , when this is positive energy is put into the system, in this case the force is in the opposite direction of the displacement. Negative work is output energy properly called exergy, w = -f.d, in this case the force is in the direction of the displacement, for example, dropping a ball is exergy, the displacement is in the direction of the force of gravity. This is exergy, work is taken out of the system as opposed to lifting the ball which required putting work into the system. Maxwell had a problem with quaternions because physicists defined positive work as dropping the ball, and the rules of quaternions said dropping the ball is a negative sign and thus exergy, work out, not work in. Around the 1900 this was a major conflict and the physicist won and decided to change the sign on vectors squared , I2 = -1 to +1, so dropping the ball would be positive energy. This is incorrect physics and incorrect mathematics. The sign of the scalar work is negative for work out and positive for work in. This is seen in opposites attract, you get work out and the sign is negative. For like charges the sign is positive and you have to put work in.

How can I train my dog to fetch a ball and bring it back to me without dropping it?
To train your dog to fetch a ball and bring it back without dropping it, start by teaching them to retrieve the ball and bring it to you. Use positive reinforcement, such as treats or praise, to reward them when they successfully bring the ball back. Gradually increase the distance they have to fetch the ball and practice consistently. Encourage them to hold onto the ball by using a command like "hold" and rewarding them when they comply. With patience and practice, your dog can learn to fetch the ball and bring it back without dropping it.
