26.4 Energy Stored in a Charged Capacitor
Stanley Liu
Summary of what happens when open/close a switch connected to a capacitor and battery.
Work must be done to move a charge from one
plate to another. In process of moving, you create a
potential differe

1) The force on a particle of mass m depends on position such that F(x) = ax2+ bx when the particle is
constrained to move along the x-axis. The particle starts from rest at xi =

Significant Figure: Addition and Subtraction
Rules:
For addition and subtraction, look at the decimal portion (i.e., to the right of the decimal
point) of the numbers ONLY. Here is what to do:
1) Count the number of significant figures in the decimal port

Significant Figures
Rules:
1) ALL non-zero numbers (1,2,3,4,5,6,7,8,9) are ALWAYS significant.
2) ALL zeroes between non-zero numbers are ALWAYS significant.
3) ALL zeroes which are SIMULTANEOUSLY to the right of the
decimal point AND at the end of the nu

Significant Figures: Multiplication and Division
Rules:
The LEAST number of significant figures in any number of the problem determines the
number of significant figures in the answer.
This means you MUST know how to recognize significant figures in order
