Question

Rachel is wearing roller skates and is standing next to a wall. She pushes off from the wall and then glides to a stop. Plan an X in the lines next to all the statements that you think are true about Rachel’s motion.
__ The force from the wall is becoming less and less as Rachel glides on her skates.


__ Rachel’s motion energy is naturally going down and the energy is disappearing.

__ Rachel’s motion energy is being turned into other types of energy.


__ There is a force by the ground slowing Rachel down.


__ There is a force by the ground that keeps Rachel moving for a while before she stops.

Answer 1

Answer:

The correct option is;

Rachael's motion energy is being turned into other types pf energy

Explanation:

Here we have Rachael pushing off from the wall to generate motion energy. The motion energy makes Rachael glide such that she is displaced while at the same time she overcomes resistances to the motion, (rolling) of the tires  from the ground as well as generates some audible noise and heat. These are all forms of energy that takes up the initial motion energy that Rachael had.
