What is the change in position of an object?
In physics, motion is a change in position of an object over time. Motion is described in terms of displacement, distance, velocity, acceleration, time, and speed.
Motion, Position, Velocity, And Acceleration. An object's change in position with respect to time is known as its displacement. The velocity of an object is found by taking the derivative of the position function: . Velocity can be thought of as the object's speed and direction, or change in position over time.
- Change of position is a defence to a claim in unjust enrichment which operates to reduce a defendant's liability to the extent to which his or her circumstances have changed as a consequence of an enrichment.

Question Answer What two factors determine speed? distance & time What is the difference between speed and velocity? Velocity has direction speed does not. What best represents acceleration as presented on a graph? velocity change vs. time What is force? a push or pull acting on an object.
- The unit of acceleration is change of position per unit of time per unit of time, such as meters/second/second. Acceleration can be positive or negative. Velocity is an object's change of position per unit of time. Acceleration is the rate at which velocity changes in a unit of time.
the change in position of one object in relation to the position of some fixed object/ Distance. a measure of the total length along a path between two points. Displacement. a measure of both length and the direction of an object's path from its starting point straight to its ending point.
- The object in motion is usually in front of a reference point-an object that appears to stay in one place. The rate at which an object moves is called speed. Speed depends on both time and distance. The velocity of an object is how fast it is going in one direction.

- The Physics Department- Mechanics, Curved Motion. Obviously, curved motion is motion along a path that is not straight. Therefore, an object following any type of curved motion will necessarily be changing its direction as it moves. So, if an object travels in a curved path, it changes velocity, and, thus, accelerates.
A change in position is evidence that motion happened. Describing Motion. It is easy to describe motion if it takes place in a straight line. An object's position can be described by showing how its distance from the reference point changes with time.
- You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.
- The distance an object travels per unit of time. The speed of an object at one instant in time. A push or a pull exerted on an object. A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second.
- In physics, position is usually a number on an axis. A number where direction doesn't matter is called a scalar. Position is a vector, because direction matters. But distance is a scalar. Distance is how far you've traveled.
