Question

What are 3 ways energy can be transferred from one object to another?
Answer:
Answer:
Answer:
2) Describe how heat travels in terms of temperature differences.
3) If you wanted to give initial spring energy to an object, what would you have to do to it?

Answer 1

1) Three ways energy can be transferred:
- Conduction — direct contact, energy passed by particle collisions or electron movement.
- Convection — bulk movement of a fluid carrying energy.
- Radiation — transfer by electromagnetic waves (e.g., infrared), no contact needed.

2) Heat travels from regions of higher temperature to regions of lower temperature, spontaneously until thermal equilibrium is reached. The rate of heat flow depends on the temperature difference (the gradient) and the properties of the materials (e.g., thermal conductivity).

3) To give initial spring energy to an object you must displace the spring from its equilibrium (compress or stretch it) by doing work on it to store elastic potential energy, then attach/release the spring so it does work on the object, converting that stored energy (usually into kinetic energy).
