Law of Conservation of Charge states that the total charge of a closed system is constant. 
Law of Conservation of Energystates, energy cannot be created or destroyed but is converted from one form into another or the total amount of energy in the universe is constant. 
Law of conservation of momentumstates, the total momentum of an system remains constant if no external forces act on the system. 
Lenz's law states the direction of the induced emf is such as to tend to oppose the change producing it. (s)

Lightyear ly, is the distance traveled by light in one year in a vacuum or empty space. (d) 
Linear momentum is the product of mass and velocity, $$p= m v$$. (d) 
Loglog plots are used to find the value of the exponent $$n$$ and coefficient $$a$$ for the general relationship $$ y= a x^n$$. The value of the gradient for the loglog plot equals $$n$$ and $$a= log^{1}{(\text{yintercept})}$$. For example A linear relationship should have $$n \approx 1$$; A squareroot relationship should have $$n \approx \frac{1}{2}$$; A quadratic relationship should have value $$n \approx 2$$; An inversesquare relationship should have value $$n \approx 2$$. 
LSBleast significant bit is the rightmost or the trailing bit in a binary number. 
Luminosity is the power radiated or energy radiated per unit time by a star. (d)
