________ is a change of position. 

The correct answer is Motion.

Key Points

• Motion is the process of moving or being moved, as well as a change in the position of an item.
• The term "body in motion" refers to when a body's location in relation to its environment changes.
• Motion is mathematically characterised in terms of displacement, distance, velocity, acceleration, and speed as well as the observer's frame of reference and the measurement of the change in the body's position with respect to that frame as time passes.
• Kinematics is the field of physics that studies forces and their effects on motion, while dynamics studies the motion of objects without regard to their source.

Additional Information

•  Speed
  • The distance travelled in relation to the time it took to travel that distance is how speed is defined. As speed simply has a direction and no magnitude, it is a scalar quantity.
• Velocity
  • In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea. A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined.
• Distance
  • Distance is the scientific term used to describe how far an object has moved. A scalar quantity, distance. The International System of Units defines a metre as the distance unit.
