No, Newton's Cradle is not an example of a perpetual motion machine. A perpetual motion machine hypothetically runs forever via some external, infinite power source (or, alternatively, it simply requires no additional momentum to continue). However, a Newton's Cradle does not continue forever: its energy slowly falls over time, making it non-perpetual.
F=M*A (F=force m=mass A=acceleration) force equals mass times acceleration
a machine applies a force of 100 newtons over a distance of 10 meters to raise a500 newtons drum 1.5 meters. what is efficiency of the machine ?
Newtons concept of the world machine was that the universe is like a perfect machine created by god wich works by the laws of physics.
The mechanical advantage of a simple machine in this scenario would be 5. This is calculated by dividing the output force (200 newtons) by the input force (40 newtons).
newtons third law of motion
that movie leathal weapon
no, it would be a violation of Newtons third law...it would have to generate more energy than the energy it usesFor every action, there is an equal and opposite reaction.I think it is. I think about satellites. The definition of a pmm is once you start it you don´t need any extra power to keep it going. Satellites don´t get any extra power after they have been launched. gravity does the rest of the work for eternity as long as no meteorite crashes intothe satellite.
Multiply kilograms by the acceleration due to gravity (9.8 m/s^2). The formula is: F = M * A F = Force (AKA Newtons, in the following example) M = Mass A = Acceleration For example: 60 kilograms needs to be converted to Newtons. 60*9.8 = 588 Newtons
The mechanical advantage (MA) of a machine can be calculated using the formula: MA = Load Force / Effort Force. In this case, the load force is 1700 newtons and the effort force is 340 newtons. Therefore, MA = 1700 N / 340 N = 5. This means that the pulley system provides a mechanical advantage of 5, allowing a smaller force to lift a heavier load.
A medium-sized refrigerator or a grand piano typically weigh around 1000 Newtons. Wildlife, such as a large adult reindeer or a black bear, can also weigh close to 1000 Newtons.
If the mechanical advantage of the pulley is 1, then the input force needed to lift the 900-newton refrigerator is also 900 newtons. This means that the moving company would need to apply a force of 900 newtons to raise the refrigerator to the second floor.
The difference between 200 newtons and 20 newtons is 180 newtons.
