Kinetic + gravitational potential energy + energy stores Flashcards
1
Q
where is kinetic energy found
A
in a moving object
2
Q
what is the formula for kinetic energy (Ek)
A
Ek = 0.5 * m * v^2
3
Q
what is v and what our its units
A
speed m/s
4
Q
What is gravitational potential energy
A
objects raised above ground level
5
Q
what is the formula for gravitational potential energy (Ep)
A
Ep = m *g * h
6
Q
what does h represent
A
shows height in metres
7
Q
where is energy stored
A
inside a system by particles (internal energy)
8
Q
What happens when heat is applied to system of particles
A
increases particle energy causing raise in temp or state change
9
Q
what is the increase in temp of system dependent on
A
mass of substance heated, type of material and energy inputted
