This is a collection of physlet activities on Newton's laws, consisting of both
qualitative and quantitative problems. It is part of a collection of web pages
with embedded java applets (href="http://webphysics.davidson.edu/physletprob/Default.htm">Physlets) that
can be used to develop on-line homework or tutorial applications. Each item
illustrated is part of an on-line homework problem collection distributed along
with a textbook written by target="_blank">Giancolli. Following is a short summary of each item in
8.2.1: A large block and small block are in contact, and are pushed
by an external force on a horizontal frictionless surface. Masses are
given, and the student measures the acceleration from data collected from the
motion. The force of contact between the blocks is calculated when the
external force is applied to the large block and to the small block.
8.2.2: Force Concept Inventory-type problem where an external force
(thrust) is applied to a "floating satellite."
8.2.3: A horizontal force presses a block against a vertical
wall. The student measures the acceleration downward, and calculates the
external force. The coefficient of friction is given.
8.2.4: A small block slides on top of a large block. Both
block slide on a frictionless surface. The student measures the
accelerations of the large block to determine the coefficient of friction
between the blocks.
A.1: Two equal and opposite external forces are applied to a block
at various distances from an axis of rotation. The student is asked to
identify the physical and non-physical animations.
A2: A wagon carries a block on its frictionless bed,
and is pulled
to the right by a string. The animation is not physical, and the student
is asked to explain why.
A3: A simulation shows two masses connected by a string which is
draped over a pulley. The ratio of the masses may be specified by the
student. A series of questions is asked that relate to motions observed
when the mass ratios are varied.
A4: A woman in an elevator is standing on bathroom scales when the
cable breaks ...
A5: Similar to 8.2.3
A6: Similar to 8.2.3 (non-constant velocity).
A7: A woman in an elevator stands on bathroom scales as it moves up
at constant velocity.
A8: Similar to 8.2.2, but with a momentary push.
