2D Motion

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Physics Education Technology (PhET) University of Colorado
Grade Level: Secondary, Post-secondary

Abstract: Learn about velocity and acceleration vectors. Move the ball with the mouse or let the simulation move the ball in four types of motion (two types of linear, simple harmonic, circle). See the velocity and acceleration vectors change as the ball moves.

Accelerated motion in one dimension

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: 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.

Accelerated motion in one dimension (application)

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: Solving problems is an essential part of the understanding process.

Accelerated motion in two dimensions

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: 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.

Accelerated motion in two dimensions (application)

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: Solving problems is an essential part of the understanding process.

Acceleration

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Secondary

Abstract: 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

Analysis framework for laws of motion

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: A planned approach to problems is essential to effectively apply laws of motion.

Analysis of resultant motion

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Secondary, Post-secondary

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

Analyzing collision

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: Analyzing collision situation involves application of basic conservation principles in a closed system.

Angular momentum

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: The angular momentum in rotation is a subset of angular momentum about a point in general motion.

Angular momentum (check your understanding)

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: Objective questions, contained in this module with hidden solutions, help improve understanding of the topics covered under the module "Angular momentum".

Angular quantities for general motion

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: Angular quantities are not limited to rotation about fixed axis only.

Attributes of one dimensional motion

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: 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).

Balanced force system

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: Resultant of a balanced force system is zero.

Center of mass

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: There is a characteristic geometric point of the three dimensional body in motion, which behaves yet as a particle.

Center of mass and rigid bodies

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: Under certain condition, COM of rigid bodies is same as geometric center.

Center of mass (check your understanding)

Rating:
Type: Course Related Materials
Subject: Science and Technology
Collection: Connexions
Grade Level: Post-secondary

Abstract: Objective questions, contained in this module with hidden solutions, help improve understanding of the topics covered in the modules "Center of mass" and "Center of mass and rigid bodies".
