Video on Motion

Relativity theory dhows that all motion is relative since it can only be measured relative to a given observer. These measurements are also reversible such that if I see someone moving a given direction at a given speed, he sees me going the opposite direction at the same speed.

Motion in Physics How it Moves

Motion: The change in an object’s location of with respect to time.

Strait line motion is the most basic form of motion. It is strait ling with no force involved thus no acceleration and a constant velocity. Circular motion is motion around a central point it results from a force being applied to an object at a right angle to the objects motion such as gravity keeping a satellite in orbit is a good example.

Relativity theory shows that all motion is relative since it can only be measured relative to a given observer. These measurements are also reversible such that if I see someone moving a given direction at a given speed, he sees me going the opposite direction at the same speed.

Motion is describes the changing of location of an object. Motion can be both strait and curved. It can only be described relative to a chosen point of reference. Motion is how we get from place to place.
