You can multiply the amount of torque in Newton-meters by the rotational speed in order to find the power in watts. Another way to look at power is as a unit of speed (m/s) combined with a unit of force (N). If you were pushing on something with a force of 1 N, and it ...
How to find kinetic energy from momentum? A 0.300 kg ball has a speed of 15.0 m/sec. What is its kinetic energy? If the speed were doubled, what would be its kinetic energy? Is kinetic energy a state function? Your car has a dead battery. It is initially at rest, ...
How do you find velocity kinematics? Velocity, Acceleration, and Air Resistance Because kinematics equations are used when the acceleration of the object is constant, we can use a simple equation to determine the average velocity of an object. To find the average velocity, simplyadd the initial ...
How to find the total momentum of two objects? Is force the derivative of momentum? Why is momentum always conserved in elastic and inelastic collisions? What is the equation for the law of conservation of momentum? Is momentum a form of energy?
During an impact, the energy of a moving object is converted into work, and force plays an important role. To create an equation for the force of any impact, you can set the equations for energy and work equal to each other and solve for force. From there, calculating the force of an...
Again, the first step is to set the equations for energy — this time kinetic energy — and work equal to each other and solve for force. W=KE=Fd=12mv2⟹F=1/2mv2d The final step is to plug the values from the problem into the equation for force: F=1/2(2,200)(20)20.75=586...
hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. The world's hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable Energy ...
The Kinetic Furnace was sitting to the rear of the conference room. I understand that it does not produce anomalous energy after being transported on a truck. Did it ever produce anomalous energy? I found out that one of the inventors had died. Jed's point struck home. It was a pleasure...
The heat capacity formula comes in various forms, but they all amount to the same basic equation: Q = mCΔT This equation simply states that the change in heat Q of a closed system (a liquid, gas or solid material) is equal to the mass m of the sample times the temperature change ...
How much energy can one atom make?A surprisingly large amount! That was what physicist Albert Einstein meant when he wrote out this simple and now famous equation:E = mc2If E is energy, m is mass (the scientific word for the ordinary stuff around us), and c is the speed of light, ...
