NCERT Physics Class 11 Course: NCERT Physics Class 11 > Unit 6 Lesson 7: Work and energy problems involving friction Energy dissipated by friction Work energy problem with friction
- Thermal energy, temperature, and heat (video) | Khan Academy
Thermal energy refers to the kinetic energy of randomly moving particles in a substance Particles can have translational, rotational, and or vibrational kinetic energy, depending on the state of matter Temperature is a measure of the average kinetic energy of the particles in a substance
- Thermal energy and heat transfer (video) | Khan Academy
When a warmer object meets a cooler one, energy flows until they reach the same temperature, also known as thermal equilibrium This transfer of energy between systems is what we call heat Temperature measures the average kinetic energy or motion of these particles
- Thermal conduction, convection, and radiation - Khan Academy
There are three forms of thermal energy transfer: conduction, convection, and radiation Conduction involves molecules transferring kinetic energy to one another through collisions Convection occurs when hot air rises, allowing cooler air to come in and be heated
- What is thermal energy? (article) | Khan Academy
Almost every transfer of energy that takes place in real-world physical systems does so with efficiency less than 100% and results in some thermal energy This energy is usually in the form of low-level thermal energy
- Heat and temperature (article) | Khan Academy
Scientists define heat as thermal energy transferred between two systems at different temperatures that come in contact Heat is written with the symbol q or Q, and it has units of Joules (J )
- Types of energy (article) | Khan Academy
The average thermal energy of a group of molecules is what we call temperature, and when thermal energy is being transferred between two objects, it’s known as heat
- Energy dissipated by friction (video) | Khan Academy
Learn how to find the energy dissipated by the friction force Solve an example conservation of energy problem involving thermal energy losses due to friction
