Question: Why doesn’t the skater stop moving? Justify your answer. The skater does not stop moving because when it starts from a height that gives the energy to move to the other side of the high and that hight then gives the energy to go to the other side of the track where it came from, it all repeats leading it to not stop. ( the hill of the track gives it energy to go to the other side of the hill and so on).

Question: If the skater was in the same positions on the right side, would you expect the diagrams and the speed to look the same? Why?
If the skater was in the same position on the right side, I would expect the diagrams and the speed to look the same because it is not the side that matters what matters is the hight. Any where it is all that matters is the same height which would give the same diagrams and the speed to look the same.

Next, using the L shaped ramp.
Question: Describe the transfer of energy and explain WHY the skater has each type of energy.


Next, on the W shaped ramp:
Question: Consider the two low points in the ramp. At which point will the skater have the maximum kinetic energy? Why do you think that is?

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
