Energy conversion from potential energy (the energy of position or composition) to kinetic energy (the energy of motion) is illustrated by the diagram of a roller coaster. When the coaster is in position A, the potential energy is drag and drop answer here and the
kinetic energy is drag and drop answer here As the coaster moves to position B, the potential energy is
drag and drop answer here and the kinetic energy is drag and drop answer here As momentum carries the
coaster into position C, the potential energy is drag and drop answer here and the kinetic energy is
drag and drop answer here Finally as the coaster reaches position D, the potential energy is
drag and drop answer bere
and the kinetic energy is drag and drop answet here

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i.e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that
