written by Wolfgang Christian and Mario Belloni
This item is an applet-based problem for introductory physics on the topic of inertia in motion.  A satellite floats at constant speed when its thrusters engage and produce a constant force perpendicular to the original motion.  What is the resulting path of the satellite? Users choose a correct response from four animations.  Physlet-based problems are intended to probe student understanding, elicit misconceptions, and serve as a springboard for discussion.  Electronic student response systems (clickers) are often used to allow anonymous "voting" on the correct answer.  

SEE RELATED ITEMS BELOW for a link to the full collection of introductory physlet-based problems and for a companion problem about an object at constant velocity receiving a momentary push.

Please note that this resource requires at least version 1.1 of Java.

4. The Physical Setting

4F. Motion
  • 6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
  • 9-12: 4F/H1. The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.
  • 9-12: 4F/H4. Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.
  • 9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.

Next Generation Science Standards

Disciplinary Core Ideas (K-12)

Forces and Motion (PS2.A)
  • The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion. (6-8)
  • Newton's second law accurately predicts changes in the motion of macroscopic objects. (9-12)

Science and Engineering Practices (K-12)

Developing and Using Models (K-12)
  • Modeling in 9–12 builds on K–8 and progresses to using, synthesizing, and developing models to predict and show relationships among variables between systems and their components in the natural and designed worlds. (9-12)
    • Use a model to provide mechanistic accounts of phenomena. (9-12)

Topic: Dynamics: Forces and Motion
Unit Title: Newton's First Law & Inertia

A simulation-based problem that supplements the problem above on momentary push.  A satellite is floating at constant velocity when its thrusters engage.   The resulting path of its motion will differ from the example above.  Assesses student understanding of how resultant motion is affected by a sustained force produced by thrust.
