Energy Flashcards
(14 cards)
How can waste heat be reduced?
Using lubrication or thermal insulation to contain heat.
What is conduction?
Energy transfer, heat or electric charge, through a substance.
Why will theoretical velocity not normally be reached?
Due to friction and resistance.
What energy change occurs when an object accelerates by a constant force?
Object’s kinetic energy increases as work is being done, object accelerates at a constant rate.
What energy change occurs when a vehicle slows down?
It’s kinetic energy decreases, transferred to thermal energy, possibly in brakes, surfaces, and air; it decelerates.
What is spring constant measured in?
N/m.
What is gravitational field strength measured in?
N/kg.
What is volume measured in in Physics?
m³.
What is specific latent heat measured in?
J/kg.
What is weight measured in?
Newtons.
What is momentum measured in?
kg×m/s.
What is a period measured in?
Seconds.
What is wave speed measured in?
m/s.
What is magnetic flux density measured in?
Tesla.
