The nature of acceleration is determined by the net external force for constant mass system. Depending on the nature of force, there exists wide range of possibilities like zero, constant or varying accelerations in one dimensional motion.
Solving problems is an essential part of the understanding process.
Motion in two dimensions with one dimensional acceleration (projectile) is analyzed with component motions in coordinate system, whereas motion in two dimensions with two dimensional acceleration (circular motion) is analyzed with the help of component accelerations - tangential and normal accelerations.
Solving problems is an essential part of the understanding process.
The rate of change of velocity with time is called acceleration. Most of the real time examples of motion are accelerated in variety of ways - despite the fact that the basic nature of the matter is to maintain its velocity in both direction and magnitude
A planned approach to problems is essential to effectively apply laws of motion.
Analysis of resultant motion is best fit to the principle of independence of motion in mutually perpendicular directions.
Analyzing collision situation involves application of basic conservation principles in a closed system.
This lab activity has students rolling a marble down a ramp to study position, velocity, and acceleration. Based on a experiment performed by Galileo.
The angular momentum in rotation is a subset of angular momentum about a point in general motion.
Objective questions, contained in this module with hidden solutions, help improve understanding of the topics covered under the module "Angular momentum".
Angular quantities are not limited to rotation about fixed axis only.
Artificial satellites are the backbone of modern communication systems.
One dimensional attributes need careful interpretation because a vector quantity, inherently different to scalar, is represented by a signed scalar (positive or negative) quantity with superimposed notions of two concepts (scalar and velocity).
Resultant of a balanced force system is zero.
Solving problems is an essential part of the understanding process.
This activity is a lab investigation where students design a balloon car to collect data about speed and velocity.
Students will design and build a device to protect and accurately deliver a dropped egg. The device and its contents represent a care package that must be safely delivered to people in a disaster area with no road access. In a similar fashion to a team of design engineers, students will design their devices using a number of design constraints including limited supplies. The activity emphasizes the change from potential energy to kinetic energy of the device and its contents and the energy transfer that occurs on impact. Students will enjoy this activity and attain deeper understanding of mechanical energy.
Students build their own roller coasters using pipe insulation and marbles, and then analyze them using principles of physics. They examine conversions between kinetic and potential energy and frictional effects to design roller coasters that are completely driven by gravity. A class competition is then held to determine the most innovative and successful roller coasters.
This Internet resource provides introductory information, concept or skill development in Mathematics for grade 9, 10, 11, and 12 students who are at grade level in a single student situation. This text was initially written by David Guichard. The single variable material (not including infinite series) was originally a modification and expansion of notes written by Neal Koblitz at the University of Washington, who generously gave permission to use, modify, and distribute his work. New material has been added, and old material has been modified, so some portions now bear little resemblance to the original.
This digital textbook was reviewed for its alignment with California content standards.
