System 2
1.
Which system has more potential energy? Explain.
2.
Which system has more kinetic energy? Explain.
3.
Which system has more total energy? Explain.
1.
System 2 has more potential energy. Both boulders are the same mass,
and are not moving, therefore they have the same velocity. System 2
has a boulder at a higher height, thus it has more potential energy.
2.
Both systems have the same amount of kinetic energy. Both boulders
are on the cliff and at rest, therefore their velocity is 0. As such, they
have the same kinetic energy.
3.
System 2. The total energy of a system is given by its potential energy
and kinetic energy. Since both systems have the same kinetic energy,
the system with the greatest potential energy has greater total energy.

Which system has more potential energy? Explain.

Which system has more total energy? Explain.
Started from
the cliff
1.
System 2 has more potential energy. Both boulders are the same mass.
While system 1 has a boulder that is moving, an object’s speed does not
affect its potential energy. System 2 has a boulder at a higher height,
and so therefore has more potential energy.
2.
System 1 has more kinetic energy. Only system 2 has a boulder on the
cliff and at rest, therefore its velocity is 0 while system 1 has a moving
object. As such, they have the same kinetic energy.
3.
Both systems have the same amount of energy. The total energy of a
system is given by its potential energy and kinetic energy. Since the
boulder in system 1 started at rest from the same height as system 2, the
systems must have the same amount of energy since energy cannot be
created or destroyed.

V ≠ 0
1.
Systems 1 and 2 have the same amount of energy. Both systems have
boulders that are the same mass and at the same height. The velocity of
an object does not affect its potential energy.
2.
System 1 has more kinetic energy. System 2 has a boulder at rest (no
kinetic energy; only potential energy), while system 1 has a boulder that
is moving. Therefore, system 2 has more kinetic energy.
3.
System 1. The total energy of a system is given by its potential energy
and kinetic energy. Since both systems have the same potential energy,
the system with the greatest amount of kinetic energy has greater total
energy.
3.
If I double the velocity an object moves, what
happens to the amount of energy?
2.
If I triple the height from which an object is
dropped, what happens to the amount of
energy?
The amount of energy doubles. E = m * g * h
The amount of energy triples. E = m * g * h
The amount of energy quadruples. E = ½ m * v

height, mass, velocity
Spring 2. Spring 2 has a mass that weighs more and so is
pushing the spring down a greater distance. In this
instance, the spring is what stores the potential energy.
