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.

Analysis of resultant motion is best fit to the principle of independence of motion in mutually perpendicular directions.
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".

Students examine how different balls react when colliding with different surfaces, giving plenty of opportunity for them to see the difference between elastic and inelastic collisions, learn how to calculate momentum, and understand the principle of conservation of momentum.
In this activity, students examine how different balls react when colliding with different surfaces. Also, they will have plenty of opportunity to learn how to calculate momentum and understand the principle of conservation of momentum.
This is a case study designed to facilitate the learning of conservation of momentum and inelastic collisions. There are other physics concepts ingrained in the mathematics that are needed when examining this case.
This simulation represents the case of an object sliding frictionless over the surface of a flat disk that is rotating. I will call the object 'the puck', as in ice hockey. The 'Distance' in the simulation is the distance to the disk's rotation axis. The 'Velocity' is relative to the disk; 0.3 velocity means that at the instant of being launched the puck's velocity relative to the disk is 30% of its co-rotating velocity at that particular distance to the rotation axis. That is, close to the rotation axis 0.3 represents a slower velocity than close to the disk's rim.
The disk supports the weight of the puck, but since there is no friction the rotation of the disk does not affect the motion of the puck. So there's no dynamics going on; there is no exchange of momentum, no change of kinetic energy.
Investigate collisions on an air hockey table. Set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum conserved? Is kinetic energy conserved? Vary the elasticity and see what happens.
As a continuation of the theme of potential and kinetic energy, this lesson introduces the concepts of momentum, elastic and inelastic collisions. Many sports and games, such as baseball and ping-pong, illustrate the ideas of momentum and collisions. Students explore these concepts by bouncing assorted balls on different surfaces and calculating the momentum for each ball.
In this interactive activity adapted from the University of Toronto, observe the effect of mass on momentum in elastic and inelastic collisions.
Some of the topics addressed in this book are: Conservation of energy; the transfer of mechanical energy; conservation of momentum; conservation of angular momentum; thermodynamics.

Students learn about the physical force of linear momentum movement in a straight line by investigating collisions. They learn an equation that engineers use to describe momentum. Students also investigate the psychological phenomenon of momentum; they see how the "big mo" of the bandwagon effect contributes to the development of fads and manias, and how modern technology and mass media accelerate and intensify the effect.
