NEXUS/Physics Clicker Questions
A mass is hanging from a spring. The position of
the mass is measured by a sonic ranger sitting
25 cm under the mass’s equilibrium position.
At some time, the mass is started oscillating.
At a later time,
the sonic ranger
begins to take data.
Which graph could
represent the
net force
on the mass?

NEXUS/Physics Clicker Questions
A pendulum swings in the plane in front of
the marked board. There is a peg
(indicated). When the ball passes the peg
it will pivot from the peg instead of from
the original pivot. How high will it go
on the right?
