Oil is set by the oil cartels and the government. They have their own reasons, including greed to set the prices the way they do.
higher income, more luxery goods. not rocket science.
It had made it much easier to clean cotton and made industries sky rocket
The fighter plane began it's inexorable journey to destruction after being hit by a rocket.
· We should be proud of the pound · Prices will rocket · It will cost £18 million to set it up · It would make it hard to get out of the current economic crisis · We would lose our individuality
I am assuming you actually did mean acceleration and not speed or velocity. Acceleration already implies a change in speed or velocity, either increasing or decreasing. For an object to change speed -- in other words, for an object to accelerate -- the sum of the forces acting upon it must be non-zero. But you asked about an increase in acceleration! That's a bit different. The change in acceleration is called jerk, which requires a bit of explanation. If you drop an object off a tall tower in a vacuum on Earth, that object will experience constant acceleration; that is, its speed will increase at a constant rate. At the end of its first second of freefall, it will achieve a speed of 32 feet per second; at the end of its second second of freefall, it will reach 64 feet per second; and at the end of its third second, it will be falling at 96 feet per second. You can see that the change in speed from one second to the next is always 32 feet per second, which implies a constant acceleration. Since the object is accelerating, we know that the sum of the forces acting upon the object is something other than zero. In fact, the force acting upon the falling object is its weight, and since there's nothing to counteract its weight, the object falls at constantly increasing speed. But what if the object reached 32 feet per second in the first second and 64 feet per second in the next and 128 feet per second in the next?! You can see that the difference in speed from one second to the next is not constant; it's increasing. That implies that the force acting on the object is not constant but is also increasing. That sort of thing happens in rocketry -- think of the space shuttle -- when the thrust forces created by the rocket motors increase greatly as they burn off fuel. A varying force will result in a varying acceleration, which is called jerk.

i dont exactly no but it is highly a lot of money for petrol...
Magnets.
Rocket fuel contains oxygen, which is not found in space. A rocket in space could theoretically work in space if it were to carry its own oxygen, but other fuels such as hydrogen are more efficient.
Wind will affect the rocket causing it to go off course or crash into a tree.
A rocket drops back to Earth due to the force of gravity pulling it down. Once the rocket's engines stop providing thrust, the gravity of Earth becomes the dominant force, causing the rocket to descend.
Team Rocket is causing the strange radio waves at the Radio Tower in Goldenrod City.
The parachute creates drag that opposes the rocket's motion, slowing it down. This drag force is generated as the parachute catches the air and creates turbulence, reducing the rocket's speed.
A good balance of propulsion and weight, and make sure that it has a good aerodynamic structure, because sometimes the nose of a rocket tends to be in a shape that creates more wind resistance.
A rocket is propelled by the force of the expanding gases produced when fuel is burned in the combustion chamber. This force pushes the exhaust gases out of the rocket's nozzle in one direction, causing the rocket to move in the opposite direction as described by Newton's third law of motion.
Resistance can affect the shape of a rocket by increasing drag, which can slow down the rocket and reduce its efficiency in reaching its intended destination. To minimize resistance, rockets are typically streamlined with pointed fronts and smooth surfaces to reduce drag and improve aerodynamics.
The main force causing a rocket to fly upwards is thrust, generated by the propulsion system. This force propels the rocket in the opposite direction of the exhaust gases expelled from the engine, overcoming gravity and enabling the rocket to ascend. Aerodynamic forces also play a role in stabilizing the rocket's flight path.
