How a ball point pen work in space?
One with a sealed cartridge, which is pressurized, would work best. The pressure would push the ink towards the ball point, eliminating the need for gravity to 'pull' the ink 'down'. See related link.
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.
How much work does the force of gravity do on a 5.45-kg bowling ball that falls a distance of 0.755 m?
4.695
In tennis on return of the serve the receiver must hit the ball in how many bounces?
No, that would be perfectly legal. Hitting the ball before it bounces is called a volley.
Is digital pen works in space?
A digital pen - that is, a stylus that "writes" on a computer screen - should work perfectly well in space, assuming that the tablet device or touchscreen would work in vacuum. In the early days of the US space program, there was a level of concern that traditional ball-point pens would not work in free-fall, because the ink was gravity-fed to the ink ball. (Ball point pens typically do not work when held upside down, for example, or when writing on a surface above the body of the pen. ) NASA commissioned the design of a "space pen" with a pressurized cartridge allowing it to write in free-fall or when inverted.
Does a ball point pen work in space?
Yes.
Why don't ballpoint pens work in space?
Lie down and write with a ball point pen upside down. after a while the pen wont work because it needs the ink to fall down to the ball point. there is no gravity in space there fore the ink will just float it wont fall Edit: why not use a pencil?
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.
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.
When a ball is in the air is work being done?
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.
When a ball is rolling on the floor and the fingers are used to stop it is work or force used?
Rolling the ball would be work and stopping the ball would be force.
Is dropping a ball doing work?
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.
