Minds On Physics Internet
Objectives - Forces in Two
The Minds On Physics program consists of 16 modules - each
covering a separate topic. Each module consists of a varying number
of sublevels. Every sublevel addresses one or two objectives. The
objectives for the Forces in Two Dimensions module are listed
Forces in Two Dimensions -
- Sublevel 1:
- The student should be able to explain the meaning of a
vector component and use that understanding to compare the
relative magnitudes of the components of a given vector.
- The student should be able to use trigonometric functions
to calculate the components of a given vector.
- Sublevel 2:
- The student should be able to analyze physical situations
in which forces act at angles to the horizontal to accelerate
objects across horizontal surfaces.
- The student should be able to determine the horizontal
accelerations of objects to which forces are applied at angles
to the horizontal.
- Sublevel 3:
- The student should be able to define equilibrium and
describe the state of objects which are at equilibrium.
- Sublevel 4:
- The student should be able to physically analyze situations
in which a weight is supported by two or more cables which
extend at angles to the horizontal.
- The student should be able to perform calculations to
mathematically relate the tension in a sign-supporting cable to
the angle with the horizontal and the mass of the sign.
- Sublevel 5:
- The student should be able to identify the forces acting
upon an object upon an inclined plane and determine the value
and recognize the importance of the components of the weight
- The student should be able to compare forces and force
components for objects placed upon inclined planes.
- Sublevel 6:
- The student should be able to mathematically analyze
physical situations involving an object upon an inclined
