Which quantity has the same dimension as that of gravitational potential?
The quantity that has the same dimension as gravitational potential is potential energy. Both gravitational potential and potential energy are measured in joules (J) or its derived units, indicating the amount of stored energy based on an object's position in a gravitational field.
What does combustion of fuel inside an engine produce?
It produces a transfer of energy...from potential to kinetic, or Torque when it comes to an engine.
Define torque.derive its unit?
Torque is vector energy. Physicists have mistakenly defined energy as a scalar. Energy is a quaternion consisting of scalar energy (potential) and vector energy (torque). The units of torque is Joules or Newton meter, the same as work or energy..Here is the correct definition of Energy = FD = -F.D + FxD where F is force vector in Newtons and D is displacement vector in meters.F.D = - FDcos(Angle) is the Work or scalar energy and FxD=FDsin(Angle) is the Torque or vector energy. If the angle between the force and displacement is 90 degrees there is only torque; if the angle is a zero degrees there is only work or scalar energy ; if the angle is not a multiple of these two angles there is both scalar and vector energy; work and torque. E.g FD= -Fdcos(45) + Fd sin(45) gives work and torque.
Which torque is absent in energy meter why?
The torque absent in an energy meter is the viscous torque. This type of torque is not present because energy meters are designed to measure the energy consumed or generated by a system, and viscous torque is a resistive torque generated due to viscous fluid flow which does not contribute to the energy measurement.
What is the significance of torque in generators?
Torque is crucial in generators as it directly affects their efficiency and output power. It represents the rotational force required to convert mechanical energy into electrical energy. A sufficient torque ensures that the generator can maintain a constant speed, which is essential for stable voltage and frequency in the generated electricity. Inadequate torque can lead to decreased performance and potential damage to the generator system.
What is the equation for mechanical power?
Mechanical power is typically calculated as the product of force and velocity, or torque and angular velocity. The equation for mechanical power can be expressed as P = Fv or P = τω, where P is power, F is force, v is velocity, τ is torque, and ω is angular velocity.
Why torque is imporatnt in hydraulic pump?
Torque is crucial in hydraulic pumps because it determines the pump's ability to convert mechanical energy into hydraulic energy effectively. Sufficient torque ensures that the pump can overcome internal resistance and maintain the desired flow rate and pressure. Inadequate torque can lead to inefficiencies, reduced performance, and potential damage to the pump and connected systems. Therefore, understanding and managing torque is essential for optimal hydraulic system operation.
Is chemical energy kinetic energy or potential energy?
Chemical energy is a form of potential energy stored in the bonds of chemicals. When these bonds are broken, the potential energy is converted into other forms of energy, such as kinetic energy.
What type of energy is torque?
rotational energy
How are potential and kinetic energy related?
Potential and kinetic energy are related in that potential energy is stored energy that can be converted into kinetic energy, which is the energy of motion. When an object has potential energy, it has the potential to move and therefore has the potential to have kinetic energy.
What are the two types of potential energy?
There is chemical potential energy, heat potential energy, elastic potential, and gravitational potential energy.
Does everything have potential energy?
No, not everything has potential energy. Potential energy is the energy that an object has due to its position or state, such as gravitational potential energy or elastic potential energy. Objects that are stationary or at rest may not have potential energy.
