When you let go, the bow springs back to its original shape and the bowstring moves back to its original position. The movement and energy propel the arrow from the bow at high speed Two factors determine the amount of energy a bow can hold. Its draw weight is the amount of force ...
Amp to Watt conversion: Learn how to calculate watts from volts and amps in both DC and AC circuits. Understand the impact of power factor & reactance on the calculation.

To accurately compare the Work required by a typically sized male gymnast to do a push-up against the much longer-armed and heavier Shag would require understanding and applying the International System of Units derived for Work (measured as “Joules”) and Force (measured as “Neutons”). ...
: 5 (mass) x 9.8 (gravitational acceleration of the earth) x 1 (height) = 49 joules of energy. This means that 49 joules of energy are required to lift the box to a height of 1 meter, and the force at which the box is pushing down on you is equal and opposing (49 joules)....
How to find the density of an object? What is the density in g/mL of a sphere with a diameter of 4.00 cm and a mass of 1.35 g? How do you convert calories to Joules using a formula? What units are used to measure force?
If the resultant force acting on a 2 kg object is equal to (3i+4j) N, what is the change in kinetic energy as the object moves from (7i-8j) m to (11i-5j) m? An object of mass 7.4 kg is moving with an initial kinetic energy 455 Joules. If the object undergoes a displacement...
Heat is one of the seemingly countless forms of the quantity known as energy in physics. Energy has units of force times distance, or newton-meters, but this is usually called the joule (J). In some applications, the calorie, equal to 4.18 J, is the standard unit; in still others, th...
Suppose a spring has a natural length of 20 cm, and 5 J of work is needed to stretch it from a length of 40 cm to a length of 50 cm. How far beyond its natural length will a force of 20 N ...
