Physics Practice Problems: Work and Energy

Work and work-energy theorem: 1. A 2kg crate rests on the floor. How much work is required to move it at constant speed a) 3m along the floor against a friction force of 4N, b) 3m along a frictionless air table, c) 3m vertically? 2. A 2-kg object is being pushed by a horizontal force F along a horizontal frictionless air-table.

Heat, Temperature, and Thermal Energy • Thermal energy Eth is an energy of the system due to the motion of its atoms and molecules. Any system has a thermal energy even if it is isolated and not interacting with its environment. The units of Eth are Joules. • Heat Q is energy transferred between the system and

Principles of Electromechanical Energy Conversion

• The actual process of converting electric energy to mechanical energy (or vice versa) is independent of: – The loss of energy in either the electric or the mechanical systems (W eL and W mL) – The energies stored in the electric or magnetic fields which are not in common to both systems (W eS) – The energies stored in the mechanical ...

Photosynthesis: How do plants get energy?

Created by LABScI at Stanford 2 Key Concepts: • Photosynthesis is the primary means by which plants get their energy. They derive this energy from a sugar called glucose (C 6 H 12 O 6). • To make glucose, sunlight is captured in pigments like chlorophyll, the substance that gives leaves their green color.
