The group decides to try allowing a round object to roll down the ramp.
they measure the initial height to calculate gravitational potential
energy, use the motion detector to track the final velocity, and calculate
the kinetic energy of the object at the end.
despite all their careful measurements, it still appears that energy is not
conserved! the object is moving faster than before at the bottom of the
ramp, but not as fast as the initial gravitational potential would have led
them to predict. which of the following suggestions is possible? select all
that apply.
there is rotational energy in the system when the mass reaches the bottom because it is
energy may still be leaving the system through friction.
there could be measurement error that accounts for the missing energy.
even though friction is diminished, air resistance could still
having an effect on the total energy.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
