How Is Work Calculated? Explanation: The formula for work is , work equals force times distance. In this case, there is only one force acting upon the object: the force due to gravity. What is the formula for work? To express this concept mathematically, the work W is equal to the force f times the
How Is Angular Momentum Related To Energy? If we push on an object in the forward direction while the object is moving forward, we do positive work on the object. Rotational kinetic energy = 1⁄2 moment of inertia * (angular speed)2. … When the angular velocity of a spinning wheel doubles, its kinetic energy increases
How Is The Energy Of The Universe Conserved? Energy was conserved. … As space expands, it releases stored up gravitational potential energy, which converts into the intrinsic energy that fills the newly created volume. So even the expansion of the universe is controlled by the law of energy conservation. How matter and energy are conserved
How Long Will A Stone Take To Fall To The Ground From The Top Of A Building 80 M High And B What Will Be The Velocity Of The Stone On Reaching The Ground? How long will a stone take to fall to the ground from the top of a building 80 m high and
What Will Be The Potential Energy Of A Pendulum In An Extreme Position? The kinetic energy of the bob of the pendulum is zero at the extreme positions while its value is maximum when it passes through its mean position. … The potential energy of the bob of the pendulum is maximum at the extreme
How Does Friction Affect Total Mechanical Energy? The mechanical energy of the system increases, provided there is no loss of energy due to friction. The energy would transform to kinetic energy when the speed is increasing. The mechanical energy of the system remains constant provided there is no loss of energy due to friction. How
How Much Power Is Required To Raise A 200kg? Question Answer How much power is required to raise a 200-kg crate a vertical distance of 2 m in a time of 4 s? 200 x 10 = 2000 x 2m = 4000/4 = 1000 Watts Raising an auto in a service station requires work. Raising
Which Requires More Work Lifting A 50 Kg Sack A Vertical Distance Of 2 M Or Lifting A 25 Kg Sack A Vertical Distance Of 4 M Quizlet? Which requires more work- lifting a 50-kg sack a vertical distance of 2 m or lifting a 25-kg sack a vertical distance or 4 m? Both are
Where Is Energy Stored In A Molecule? Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy. What part of a molecule stores energy? Adenosine 5′-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often
How Fast Do Molecules Move In A Gas? As a side note – gas molecules tend to move very fast. At 0 °C the average H2 molecule is moving at about 2000 m/s, that is more than a mile per second (and the average O2 molecule is moving at approximately 500 m/s). Do gas molecules
