This item is a set of animations that illustrate Newton's First Law, thrust, and conservation of momentum. A space telescope is traveling horizontally with a constant velocity. Students can observe inertia in motion as they engage any combination of four engines that exert constant forces on the object. Engine A exerts a force in the -x direction, B in the +y direction, C in the +x direction, and D in the -y direction. Registered teacher-users may edit and/or create their own text for specific student groups.
This resource is part of OSP, the Open Source Physics project, developed to promote concept building and allow students to explore physical systems that would otherwise be inaccessible.

4. The Physical Setting
6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
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)
Crosscutting Concepts (K-12)
Cause and Effect (K-12)
Cause and effect relationships may be used to predict phenomena in natural or designed systems. (6-8)
