BRAINCAKEWork, Energy and Power
Revision notes for Work, Energy and Power in OCR Physics A (H156). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- Work Done and EnergyWork done is the force multiplied by the distance moved in the direction of the force, W = Fx.
- Work Done at and Angle to MotionWork done by a force at an angle to the direction of motion can be calculated by using the component of the force that is in the direction of the…
- Principle of Conservation of EnergyEnergy is the capacity to do work.
- Forms of EnergyKinetic energy is the energy due to the motion of an object with mass..
- Kinetic EnergyKinetic energy is the energy due to the motion of an object with mass.
- Gravitational Potential EnergyEnergy is the capacity for doing work.
- Energy TransferEnergy can be transferred from one form to another.
- PowerPower is the rate of work done.
- Power and MotionWhen a constant force F is exerted on an object to maintain a constant speed v the rate of work done P is given by P = Fv since power = work…
- EfficiencyWhenever energy is transferred by a machine or device, only part of the input energy is transferred to the form we want.
