Gravitational Potential Energy Flashcards
1
Q
How is GPE (gravitational potential energy) calculated?
A
GPE is calculated by MASS (kg)x GRAVITATIONAL FIELD STRENGTH (9.8m/s) x HEIGHT (m).
2
Q
If the height of the ramp is increased, will the GPE of a car rolling down that ramp increase as well?
A
If the height of the ramp is increased, then the GPE of the car will increase as well. This is because the higher the ramp, the more GPE is stored in the car which will release more kinetic energy.

Q
What are the key features in sankey diagrams?
A
Key features in sankey diagrams include: labels [(input (100% or joules) output wasted (% or joules) and output useful (% or joules)] and using a ruler draw the diagram ACCURATELY.
