Answer:
Tonya's potential energy is converted into kinetic energy
Step-by-step explanation:
Potential energy:
Potential energy is a type energy possessed by a body by virtue of the position of the body.
Kinetic energy
Kinetic energy is defined as the energy of the body possessed by the motion of the body.
In the context, Tonya is standing on a rock. So Tonya has a potential energy due to her position which is equal to :
P.E. = mgh
where m = mass of Tonya
g = acceleration due to gravity
h = height of her position from the surface
When Tonya jumps into the lake, she posses kinetic energy due to her motion.
So her potential energy is transferred into kinetic energy when she jumps from the rock to the lake.
