When you throw a ball upward its kinetic energy what?
When you throw a ball upward, its kinetic energy decreases as it moves against gravity due to the work done by the force of gravity. As the ball reaches its highest point, its kinetic energy is at its minimum while potential energy is at its maximum.
A student throws the same ball straight upwards to a height of 7.50 m how much work did the student do?
The work done by the student to throw the ball upwards is equal to the potential energy gained by the ball at the maximum height. The work done is given by the formula: work = force * distance. In this case, the student exerted a force to lift the ball against gravity to a height of 7.50 m, so the work done is equal to the potential energy gained by the ball, which is mgh, where m is the mass of the ball, g is the acceleration due to gravity, and h is the height.
Is work done when a ball is dropped out of a window to the ground below?
No, work is not done when a ball is dropped from a window to the ground because work is only done when a force is applied over a distance. In this case, gravity is the force pulling the ball down, and there is no force acting against it over a distance.
A ball has a mass of 3 kg. What is the work done on this ball by the gravitational force exerted by the earth if the ball move 2 m along each of the following direection?
The work done by the gravitational force on the ball is dependent on the vertical component of the displacement. As the ball is being moved horizontally, the work done by gravity is zero as the force is perpendicular to the direction of motion. Therefore, the work done by gravity in moving the ball a distance of 2 m horizontally is zero.
When you throw a ball your hand applies blank to the ball?
When you throw a ball, your hand applies force to the ball. The force propels the ball forward, giving it speed and direction.
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.

What is the beat ball to catch Ho-oh with?
The best ball obviously is a Master Ball, but you can also try a Quick Ball. If it is at night, use a Dusk Ball after a few blows to it. If that doesn't work, throw a whole bunch of Pokèballs, lower its health a little more, and throw a Timer Ball. This should work. If not, bring out a strong Pokèmon with False Swipe, get its health down to 1 HP, and throw those Pokèballs!

What is the difference between throw me the ball and throw the ball to me?
nothing they mean the same thing
In soccer can you throw the ball of someones head and make a point?
It is quite possible, and even quite legal to take a throw in and have a team mate head the ball into the goal for a score. It's done all the time on a corner kick. The move is called headding the ball. It's quite legal.
What is scratch throw?
it is a scratch throw when you throw the ball it will go straght
How do you throw a football with an arch?
To make the football arch you must first get in throwing position and then you throw the ball slightly up at the right angle and you should get a perfect arch if done correctly
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.
What do you do with a Nerf ball?
You can throw the ball in the air and catch it. If you have a net with your Nerf ball then you can throw the ball into the net. You can also pass the ball to another person and play catch.
