Well, honey, when a ball is thrown upward, the system is experiencing an increase in potential energy and a decrease in kinetic energy. As the ball reaches its highest point, its potential energy is at its maximum and its kinetic energy is at its minimum. Once gravity takes over and brings that ball back down, the potential energy decreases while the kinetic energy increases. It's just physics doing its thing, darling.
What else can I help you with?
When a ball is thrown straight up into the air when the does the acceleration change directions?
Any object near the surface of the earth and not constrained experiences a downward vertical acceleration of 9.8 meters (32.2 feet) per second2 because of the mutual force of gravitational attraction between it and the earth.
How does gravity affect a baseball hit into the air?
When you hit a ball off a tee or hit one that's pitched to you, you are changing its momentum. In the first case, the ball has zero momentum before you hit and only a little more when you nip it and it dribbles a few away from you while everyone watching laughs. In the latter case, the thrown ball has positive momentum that the pitcher gave it, and hitting it changes that momentum from positive to negative, assuming you don't foul it straight back. (Momentum is a vector quantity, you see.) Changing an object's momentum requires you to do work on it, which requires energy. The greater the change in momentum, the more energy is required. But momentum depends upon mass as well as velocity. In other words, if two objects are going the same speed, the more massive object has greater momentum, which is why it's better to get hit in the head with a ping-pong ball dropped from three feet than a bowling ball dropped from three inches. So, a more massive -- that is, heavier -- ball will not go as far if you hit it with the same amount of energy with which you hit a lighter one.
When is a thermodynamic work said to be positive?
A thermodynamic work is said to be positive when the system does work on the surroundings. This occurs when energy is transferred from the system to the surroundings, resulting in a decrease in the internal energy of the system.
When a ball increases in speed by the same amount each second its acceleration is?
When a ball increases in speed by the same amount each second, its acceleration is constant. This type of motion is known as constant acceleration.
When energy is applied work is said to be doneexplain what it means to be done?
When energy is applied to a system to cause a change in its state or position, work is said to be done. This means that energy has been transferred to the system, resulting in a measurable effect on the system, such as displacement or a change in velocity. Work represents the transfer of energy from one form to another.
What force is acting upon a ball that is thrown in the air?
On the bullet itself, gravity and air friction.
Runner on third taking a lead is hit by a thrown ball from catcher while in fair territory is he safe or out?
He is out for interfering with a thrown ball while running out of the baseline. The same is true with a runner running to first base. Tom Seaver said that when he saw a runner running to first in fair territory he would throw the ball into his back to get the quick out.
When a ball is thrown straight up into the air when the does the acceleration change directions?
Any object near the surface of the earth and not constrained experiences a downward vertical acceleration of 9.8 meters (32.2 feet) per second2 because of the mutual force of gravitational attraction between it and the earth.
Examples of equal forces in sport?
When the force of gravity equals upthrust, the object is stationery and the forces are said to be equal. Eg. A scuba diver holding position underwater. A soccer ball will remain stationery when the force of gravity is equal to the upward force on the ball.
Can you tackle a runner by tripping him with your feet?
You can't tackle a player that doesn't have the ball in his possession. You can block any player you want -- you can even knock someone over with a pancake block -- but grabbing onto a player who doesn't have the ball and taking him to the ground would constitute holding.
Who said See the ball hit the ball?
See the ball hit the ball
A ball thrown by a boy from the roof top is what motion?
When the boy is holding the ball it has Gravitational Potential Energy (GPE).When he lets go the Gravitational Potential Energy is converted to Kinetic Energy.As the ball is falling it continues to gain Kinetic Energy, however, the friction from the air on the ball increases (Air Resistance).When the Kinetic Energy and Air Resistance become equal the ball is said to have to reached Terminal Velocity.Once the ball hits the ground the Kinetic Energy is transferred to the ground through heat (Friction) and also as sound.Remember energy cannot be created or destroyed, it is always transferred.
Was Chris Brown and rihanna get thrown in jail?
Chris might they even said it
Is a sofball harder to hit than a baseball?
It said that a softball is harder to hit because of the force it comes in at is greater in the highest levels of softball then is baseball, also the underhand motion causes the ball to have an upward movement which is hard to master then the downward movement of a baseball.
Which has more mass a bowling ball or a table tennis ball?
a bowling ball
Who said a thrown stone and a spoken word once cast can never be recalled?
Horace said "a word once spoken can never be recalled." (Latin)
How do you throwback grenades in Halo Reach?
by hitting the said thrown grenade with a grenade to thrust it back at said owner (must be stick or will bounce every were)
