P2. Motions of Objects

High School

P2.1 Position — Time
An object’s position can be measured and graphed as a function of time. An object’s speed can be calculated and graphed as a function of time.

  1. Fear of Physics, learn about position, velocity, and acceleration
    This is a site that allows a student to input different values for the components of a moving object and see how it effects all the other components.
  2. Physics Classroom - "1-D Kinematics"
    The motion of objects in one-dimension is described using words, diagrams, numbers, graphs, and equations. Lesson include, Describing Motion with Words, Describing Motion with Diagrams, Describing Motion with Position vs. Time Graphs, Describing Motion with Velocity vs. Time Graphs, Free Fall and the Acceleration of Gravity, and Describing Motion with Equations.
  3. Physics Classroom - "Kinematics: Multimedia Physics Studio"
    The motion of automobiles, Hot Wheel cars, and rockets are used to illustrate the physics of position, velocity, acceleration, and kinematic graphing.
  4. Physics Classroom - "Circular, Satellite, and Rotational Motion: Multimedia Physics Studio"
    Learn how Newton's laws apply to the motion of roller coaster riders in loops as well as planets orbiting the Sun.
  5. Physics Classroom - "Vectors & Projectiles"
    Learn about the physics of vectors and vector operations and study their application to the motion of projectiles.
  6. Physics for Physical Science
    The unit on motion in this site is very descriptive and contains a lot of graphs and animation. Subjects covered are: projectile motion, momentum, force, energy, and power.

P2.2 Velocity — Time
The motion of an object can be described by its position and velocity as functions of time and by its average speed and average acceleration during intervals of time.

  1. Chapter 2 Velocity - Motion of Objects
    This is another site that allows you to input velocity and see how it effects motion.
  2. Physics Classroom - "1-D Kinematics" - Motion of Objects
    The motion of objects in one-dimension is described using words, diagrams, numbers, graphs, and equations. Lesson include, Describing Motion with Words, Describing Motion with Diagrams, Describing Motion with Position vs. Time Graphs, Describing Motion with Velocity vs. Time Graphs, Free Fall and the Acceleration of Gravity, and Describing Motion with Equations.
  3. Physics Classroom - "Kinematics: Multimedia Physics Studio"
    Newton's laws of motion and kinematic principles are applied to describe and explain the motion of objects moving in circles; specific applications are made to roller coasters and athletics. Newton's Universal Law of Gravitation is then presented and utilized to explain the circular and elliptical motion of planets and satellites.
  4. Physics Classroom - "Vectors & Projectiles"
    Learn about the physics of vectors and vector operations and study their application to the motion of projectiles.
  5. Physics for Physical Science
    The unit on motion in this site is very descriptive and contains a lot of graphs and animation. Subjects covered are: projectile motion, momentum, force, energy, and power.

P2.3x Frames of Reference
All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion.

  1. Frames of Reference: The Basics New
    Newton's equations describe and predict the way an object moves: but moves with regard to what?
  2. Lesson 9: Relative Motion and Frames of Reference New
    Relative motion is just a way of saying that sometimes different people will say different things about the motion of the same object.
  3. Relative Motion (Frame of Reference) New
    An object may appear to have one motion to one observer and a different motion to a second observer, depending on how the two observers are moving with respect to one another.
