What are the 3 types of flexibility? There are considered to be three main types of stretching methods for muscle flexibility. These are static stretching, dynamic stretching and proprioceptive neuromuscular facilitation (PNF). Is being too flexible bad? By repeatedly pushing past “normal” range, you’re getting micro traumas, which can lead to more serious injury, such […]

Is it better to breathe through your nose or mouth when exercising?
Is it better to breathe through your nose or mouth when exercising? The nose also adds moisture and warmth to inhaled air for smoother entry to the lungs. Nasal breathing, as opposed to mouth breathing, has another important advantage, especially for effective and efficient exercise: It can allow for more oxygen to get to active […]
How fast is a DC motor?
How fast is a DC motor? DC controls adjust speed by varying the voltage sent to the motor (this differs from AC motor controls which adjust the line frequency to the motor). Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and 1000-5000 rpm for DC fractional […]
Is Absolute Zero Possible?
Is Absolute Zero Possible? Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach. How do you explain thermodynamics to a child? Thermodynamics […]
