Differenciate between speed and accleration
Answers
Answer:
difference between speed and acceleration
Speed
Speed is defined as the rate of change of the position of a body. Thus it may be understood as distance covered by the body in a unit time. So speed may be expressed as:
Speed = Distance/Time
If “d” is the distance covered by a body in time “t,” then its speed “s” is:
Acceleration is defined as the rate of change of velocity. So acceleration is the change in velocity per unit time. If a body has uniform velocity, its acceleration is zero. For a body to have acceleration, there must be a change in its velocity. Thus:
Acceleration = Velocity/Timeit has only magnitude and not any specific direction. Related to speed is another term of velocity.
Acceleration is defined as the rate of change of velocity. So acceleration is the change in velocity per unit time. If a body has uniform velocity, its acceleration is zero. For a body to have acceleration, there must be a change in its velocity. Thus:
Acceleration = Velocity/Time
