    every action there is an equal and opposite reaction. This means that any force exerted onto an object has a counterpart force that is exerted in the opposite direction back onto the first object. The first and second laws represent a break with the physics of Aristotle, in which it was believed that a force was necessary in order to maintain motion. They state that a force is only needed in order to change an object's state of motion. The SI unit of force is the newton, named in Newton's honor. Toward

    The Physics behind Car Safety Systems By changing an object’s momentum, we are able to move it either faster or slower, and eventually to a halt, depending on the amount, direction, and magnitude of the force that acts upon the object. By applying this aspect on a car’s safety systems, we are able to either reduce the risks of injuries as the results of a crash, or to avoid a crash completely. It is with this principle that seatbelts, crumple zones, air bags, and braking systems, among other features

    It is not possible to adjust the open loop voltage gain of an op-amp to enable them to be used in normal amplifier circuits so Negative Feedback is used to reduce the overall gain of the circuit. With negative feedback a proportion of the output signal is 'fed-back' to the input so that it cancels out some of the input signal and reduces the apparent voltage gain of the whole circuit. With an op-amp, negative feedback is the only way of controlling the voltage gain of the circuit. The voltage

    The avalanche increases in horizontal width because snow particles are dislodged laterally, as well. While a surface snow layer that never becomes cohesive is obviously vulnerable to this process, these avalanches often occur when external forces, such as sun and rain, weaken bonding in this layer until cohesion is little enough that some snow breaks free (Graydon and Hanson 1997). The angle of the snow slope ultimately determines at what point cohesionless snow will be able to break free, and

    To understand the lift force on a hang glider, this equation must be applied to a wing. Wings are shaped so that as air flows over the top of them, its velocity must increase and results in a greater air speed on top of the wing than on the bottom. And from Bernoulli's equation, we can see that if velocity increases, pressure must decrease. This means that air pressure is higher on the bottom of the wing than on the top, and an upward force known as lift results. Maybe this illustration will
