2
Q
What is the definition of power?
A
The rate at which energy is transferred
3
Q
How does the conductivity of a material affect how quickly heat is lost?
A
- if a metrical is a good conductor heat will be lost much faster as there will be a higher rate of energy transfer across the material
4
Q
Explain the energy transfer when a vehicle slows down.
A
The kinetic energy is transferred to heat energy due to the friction between the wheels and the breaks
5
Q
Explain how energy is lost when a ball hits the wall
