STCMS™: Energy, Forces, and Motion | Smithsonian Science Education CenterIn physics , motion is the change in the position of an object over time. Motion is mathematically described in terms of displacement , distance , velocity , acceleration , speed , and time. The motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame. If the position of an object is not changing relatively to a given frame of reference, the object is said to be at rest , motionless , immobile , stationary , or to have a constant or time-invariant position with reference to its surroundings. As there is no absolute frame of reference, absolute motion cannot be determined. Motion applies to various physical systems: to objects, bodies, matter particles, matter fields, radiation, radiation fields, radiation particles, curvature and space-time. One can also speak of motion of images, shapes and boundaries.

The Meaning of Force
Motion makes the world go 'round. Motion makes the moon go 'round too. In fact, motion makes lots of things go. When we think of motion we often think of cars, bicycles, kids running, basketballs bouncing and airplanes flying. But motion is so much more.
UNIT OVERVIEW Force and motion are fundamental to all matter in the universe. A force is energy, or it can have kinetic energy—the energy of motion. Energy can . Students may read books and other passages, work in groups to complete hands-on experiments and investigations, discuss science ideas as a class.

01 - Introduction to Physics, Part 1 (Force, Motion & Energy) - Online Physics Course
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction. For simplicity sake, all forces interactions between objects can be placed into two broad categories:. Contact forces are those types of forces that result when the two interacting objects are perceived to be physically contacting each other. Examples of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces.
