PF1.5: WORK, ENERGY AND POWER. Energy exists in many different forms, eg, kinetic energy Ek, potential energy Ug, electrical energy, and elastic (or spring) energy Es. A fundamental principle of nature is that energy cannot be created or destroyed, only transformed or transferred.
When calculating power, you should use the formula P = _________________ divided by _____________. In this formula, “P” stands for power, ____ stands for work, and _____ for time. 3. The SI unit for Power is the ______________________. C. Power Problems. 4.
Worksheet 22.2 Power and Energy 1. A 60–W light bulb is operated for an average of 5 hours per day. a. How much energy does the bulb consume in joules each day? b. How much energy does the bulb consume in kilowatt–hours each day? c. How much energy does the bulb consume in kilowatt–hours each month? (Assume 30 days per month) d. If the ...
PHYSICS FIRST PRACTICE SHEETS.book. Name: Power. Date: In science, work is defined as the force needed to move an object a certain distance. The amount of work done per unit of time is called power. Suppose you and a friend are helping a neighbor to reshingle the roof of his home.
Teacher Toolkit - The Basics of Work, Energy, and Power. Objectives: To describe the conditions under which positive and negative work are done and to use the work equation to calculate the amount of work done.
We describe the rate of energy dissipation over time as power (P), and we express power in the unit of the watt (W). Write the equation relating power to voltage and current, for an electrical resistance.
Work Power And Energy Worksheets 2024. Physics' three essential concepts are work, energy, and power. When a force (push or pull) applied to an item results in the displacement of the object, that force is said to have performed work. Energy is how we define the ability to perform work.
