Question 0

What is W_net?

Answer 0

The sum of the work done by conservative forces and by no conservative forces.

Question 1

Potential Energy Formula

Answer 1

mass * gravity * height

mgh

Question 2

What are the conservative forces?

Answer 2

Gravitational, Elastic, and Electric (GEE)

Question 3

What are the nonconservative forces?

Answer 3

Friction, Air resistance, Tension in cord, Motor or rocket propulsion, Push or pull by a person (FATMP)

Question 4

Summation of conservative and nonconservative forces is equal to W_net and _____

Answer 4

Change in kinetic energy

W_c + W_nc = ΔKE

Question 5

Nonconservative forces in relation to ΔKE and ΔPE?

Answer 5

W_nc = ΔKE + ΔPE

Question 6

Conservative forces in relation to ΔPE

Answer 6

W_c = -ΔPE

Question 7

Mechanical energy when nonconservative forces are not present

Answer 7

ΔKE + ΔPE = 0

Question 8

Conservation of Mechanical Energy when only conservative forces are working

Answer 8

E = KE + PE

Question 9

Elastic force of a spring

Answer 9

F = -kx

Question 10

KE in terms of mass and velocity

Answer 10

(.5)(m)(v^2)
