New cards

net positive work applied to a system

increases kinetic energy

2
New cards

formula for kinetic energy

½ mv2

3
New cards

gravitational potential energy

the energy of an object due to its position

4
New cards

formula for GPE

mgh

5
New cards

formula for h on an incline

h = dsintheta

6
New cards

elastic potential energy

energy that can be stored by compressing or stretching a string

7
New cards

hooke’s law

fspring = -kx

8
New cards

formula for epe

1/2kx2

9
New cards

the greater the spring constant

requires more work and stores more elastic potential energy

10
New cards

open system equation for total energy

E = Ke + GPE + EPE + Einternal = W

11
New cards

closed system equation for total energy

E = Ke + GPE + EPE + Einternal = 0
