Explain that a push or a pull is a force.
Force and Motion
Students learn how to describe the position and motion of objects and the effects of forces on objects. Students start by describing the position of one object with respect to another object (e.g., in front, behind, above, and below) and then describe motion as a change in position. Forces are introduced as pushes and pulls that can change the motion of objects, and students learn through observation that various forces act through contact while others act from a distance (without touching the object). These basic concepts about forces and motion provide a foundation for learning to quantify motion in later years.
A force is a push or a pull. Pushing or pulling can move an object. The speed an object moves is related to how strongly it is pushed or pulled.
