Question

what is the acceleration ​

Answer 1

Answer:

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

hope it helps u

please mark my answer as a brain list.

Answer 2

Answer:

Explanation:

• In mechanics, acceleration is the rate of change of the velocity of an object with respect to time.
• Accelerations are vector quantities.
• The orientation of an object's acceleration is given by the orientation of the net force acting on that object.
• SI unit: m/s2, m·s−2, m s−2
• Dimension: L T −2
