Answer:
1) Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity)
2) Scalar quantities are quantities that are described only by a magnitude. They do not have a direction of action.
3) Vector, in physics, a quantity that has both magnitude and direction. ... For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars.
4) Volume is the amount of three-dimensional space enclosed by a closed surface in terms of numerical value. For example, the space that a substance can be solid, liquid, gas, or plasma, or any space-occupying shape.
5) Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
6) Velocity: Velocity is the speed of an object moving in a definite direction. ... Velocity is a vector quantity; it has both magnitude and direction
7) Distance : The length of the actual path between the initial and the final position of a moving object in the given time interval is known as the distance travelled by the object. Distance = Length of path I (ACB) Distance is a scalar quantity. Unit In SI system :metre (m)
8) Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. ... For example- If an object moves from A position to B, then the object's position changes. This change in position of an object is known as Displacement..
