Clarifications: Each clarification provides an explanation of an indicator/objective to help teachers better understand the skills and/or concepts.

Standard 5.0 Physics

Topic A. Mechanics

Indicator 2. Explain that the changes in the motion of objects are determined by the mass of an object and the amount (size) of the force applied to it.

Objective a. Observe and give examples that show changes in speed or direction of motion are caused by an interaction of forces acting on an object:

  • Friction
  • Gravity

Clarification

Motion of an object can be described by its position, direction of motion and speed. An object in motion that is not being subjected to another force will continue to move in a straight line. A force is defined as a push or pull applied to an object causing a change in motion.
