Joule (unit of energy or work) – 1 The work done by the point of application of the Newtonian force when it moves a distance of 1 meter in the direction of the force.

Watts (unit of power) – the power that gives 1 joule of energy in 1 second.

Coulombs (unit of electricity) – The amount of electricity transported by 1 ampere of current in 1 second.

Volts (Potential Difference and Unit of Electromotive Force) – If the power drawn between two points is 1 watt in a wire flowing through a constant current of 1 ampere, the potential difference between the two points is 1 volt.

Farad (capacitance unit) - When a capacitor is charged with 1 coulomb, there is a potential difference of 1 volt between the two plates, then the capacitance of this capacitor is 1 farad.

Ohm (unit of resistance) – A constant potential difference of 1 volt is added between two points of a conductor, and if a constant current of 1 ampere is generated in the conductor and no other electromotive force is present in the conductor, the resistance between the two points is 1 ohm.

The resultant force f = f1 - f2 n

f = f1 + f2 f1 and f2 are on the same straight line and in opposite directions.

F1 and F2 are on the same straight line and in the same direction.

Pressure p = f s Papa

p = g h p = f s is suitable for solids, liquids and gases.

p = g h for vertical solid columns.

p = g h can be used to calculate the liquid pressure directly.

Buoyancy f float = g f n

Floating, levitating: f float = g n

F float = g row = liquid g v row.

Judge the amount of buoyancy according to the floating and sinking conditions (1) Judge whether the object is buoyant.

2) Judge the object according to the floating and sinking conditions of the object.

In what state.

3) Find a suitable formula to calculate buoyancy.

Object float and sink conditions (premise: the object is submerged in a liquid and subject only to buoyancy and gravity):

f float g (liquid) floats to float f float = g (liquid = matter) suspension.

f float g (liquid) sinks.
