Sources of random errors include: The observer being less than perfect The readability of the equipment External effects on the observed item Systematic errors A systematic error is an error which occurs at each reading. Sources of systematic errors include: The observer […]
Momentum: In classical mechanics, linear momentum, translational momentum, or simply momentum (pl. momenta; SI unit kg m/s is the product of the mass and velocity of an object, quantified in kilogram-meters per second. It is dimensionally equivalent to impulse, the product of force and time, quantified in newton-seconds.
Potential energy The word potential means that something is capable of becoming active. Potential energy sometimes is referred to as stored energy. This type of energy often comes from the position of an object relative to Earth. A diver on the high diving board has more energy than someone who dives into the pool from […]
