Idea that the observation of motion depends on the observer.
Measurable quantity of a particular kind such as; length, breadth, (width) depth, or height.
A measure of how fast something moves or the distance it moves, in a given amount of time.
A measure of how quickly the velocity is changing.
A force that moves an object away from another object.
Speed in a specific direction
When two forces acting upon each other are equal in size preventing motion.
Starting point you choose to describe the location (or position) of an object.
Change of position over time, an objects distance and direction from a reference point.
Push or a pull
Force objects exert on each other because of their masses.
Force that moves an object closer to another object.
When two forces acting upon each other are not equal in size causing motion.
The resistance of an object to a change in the speed or direction of its motion.
Overall force acting on an object when all of the forces on it are combined.
When one object pushes or pulls another by touching.
A force that resists motion when 2 surfaces rub together.
