In video 5 dealing with EPE, if the k value is larger , it is _______ to change the size of the spring

• harder

• easier

Which of the following choices has the equations for all three types of mechanical energies correct

• $KE\ =\ \frac{1}{2\ }kv^2\ ,\ GPE\ =\ mgh,\ EPE\ =\ \frac{1}{2}kx^2$

• $KE\ =\ \frac{1}{2\ }mv^2,\ GPE\ =\ mgv,\ EPE\ =\ \frac{1}{2}kx^2$

• $KE\ =\ \frac{1}{2}mv^2,\ GPE\ =\ mgh,\ EPE\ =\ \frac{1}{2}kx^2$
