Answer:
a. distance.
Step-by-step explanation:
- Distance is the actual length of the path travelled by a body in a given time interval. It is a scalar quantity, meaning it has magnitude but not direction.
- Velocity is the rate of change of distance with respect to time. It is a vector quantity, meaning it has magnitude and direction.
- Acceleration is the rate of change of velocity with respect to time. It is also a vector quantity.
- Moment is a physical quantity that represents the tendency of a body to rotate about a point. It is a vector quantity.
Therefore, the path length travelled by a body in a given time interval is known as a. distance
