Explain angular momentum precession and give examples.

Explanation:

Angular momentum precision:

   We know that

Linear momentum P= m. v

Rate of change in linear momentum is called force.

Angular momentum L = I.ω

            L =  I.ω

Rate of change in angular momentum is called torque .

This rate of change of angular momentum is called angular momentum precision.

Example of angular momentum:

1. Lets take a disc is connected to shaft ,When disc is rotating along its axis and shaft is also rotating .

2.When air plane take turn then they feel one torque this torque is nothing ,it is due to angular momentum precision.

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?

the body's situation won't change the forces are equal opposit and on the same body
