Ejecting from an aircraft moving at speeds greater than the speed of sound (mach 1: 750 miles per hour / 1,207 kph) can be very dangerous. The force of ejecting at those speeds can reach in excess of 20 Gs -- one G is the force of Earth's gravity. At 20 Gs, a pilot experience...

If you want to calculate the acceleration, first you need to modify the force equation to get a = F/m. When you plug in the numbers for force (100 N) and mass (50 kilograms), you find that the acceleration is 2 m/s2. HowStuffWorks You may be surprised to learn that Newton wasn...
Mr. Movellan, who designed the software, said that in the future the robot could be in museums to help people from different cultures to understand one another.1. What do we know about the robot? A.It can recognize and respond to human emotions. B.It can develop new machines for ...
Although they might sound like the perfect quick fixes, liposuction and laser cellulite treatments are not simple means of going from a size 16 to size 6 overnight. So how can you get rid of cellulite? Nothing can substitute for eating an anti-inflammatory diet and getting enough exercise. ...
Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries. Generator: The generator is ...

These cap plies are not found on all tires; they are mostly used on tires with higher speed ratings to help all the components stay in place at high speeds. The tire sidewall provides lateral stability for the tire, protects the body plies and helps keep the air from escaping. It may ...
If the pilot continually fires the fuel jets, the balloon will continue to rise. There is an upper altitude limit, however, since eventually the air becomes so thin that the buoyant force is too weak to lift the balloon. The buoyant force is equal to the weight of air displaced by the ...
If they were to let go of the hose, it would thrash around with tremendous force. If the firefighters were all standing on skateboards, the hose would propel them backward at great speed! When you blow up a balloon and let it go so that it flies all over the room before running out ...
