Answer:
Finding time period of SHM from equation of displacement
Explanation:
0
Say for example I've got the equation of a SHM as:
x=Acos(ωt+ϕ)
where A is the amplitude.
How do I find the time period of this motion?
I tried by finding the second order differential of the given equation.
a=d2xdt2=−Aω2cos(ωt+ϕ)
Comparing it with the general equation for acceleration a=−ω2x, we can find ω from here.
But that is where the problem is coming. It makes no sense if I write ω=ωA−−√.
What is the correct method to find the time period of the SHM? What am I missing?
There is a very simple mistake in your math. Notice A is part of x, it is factored so you'll get to ω=ω again. If you want to find a meaning to ωT=2π, consider the fact that cos (or sin) are periodic functions with period 2π. Hence, every time you have a time difference such that ω(t1−t2)=2π you are back at the same point. Hence the period is given by ωT=2π.
When water changes from a liquid state to a solid state, the process is called solidification (freezing), this change in matter strengthens the intermolecular forces of the molecules and is hence an exothermic reaction, which releases energy.
When water changes from a liquid state to gaseous state, the process is called evaporation (vaporization), this change in matter weakens the intermolecular forces of the molecules and is hence an endothermic reaction, which absorbs (uses) energy
Pls specify and I can help it really does not make scence?
