Want this question answered?
Acceleration is defined as the change in velocity, and is a result of a force being applied on the object in question. Acceleration will not always result in an object changing direction, but it is capable of it (in the case of centripetal acceleration, all it does is change the direction.) Acceleration is a vector, therefore a direction must always be given when a value is stated.
That's called 'centripetal acceleration'. It's the result of the centripetal forceacting on the object on the curved path.
Its changing direction ;)
"Acceleration" does not mean "speeding up". Acceleration means any changein the speed or direction of motion. An object with no acceleration moves at aconstant speed in a straight line. If its path is not straight, then the directionof its motion changes, which fits the definition of acceleration.
Centripetal means towards the center. Any object moving around in a circle is accelerating towards the center. Remember that acceleration involves a change in velocity, and a specification of "velocity" includes the direction; therefore, since the direction of the movement changes continuously, the object is "accelerating", according to the definition of acceleration.
acceleration is never a scalar...it describes in what direction is the motion of an object changing, so it can't be a scalar...

centripetal acceleration
As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
The centripetal acceleration is equal to velocity squared over radius. a=v^2/r
Acceleration in circular motion is the acceleration directed towards the center of the circle, known as centripetal acceleration. It is responsible for keeping an object moving in a circular path rather than in a straight line. The magnitude of centripetal acceleration is given by the formula a = v^2 / r, where v is the velocity of the object and r is the radius of the circle.
The Centripetal force keeps a object moving in a circle and its force and acceleration are directed toward the center of the circle
Only the direction of the velocity vector is changing. The magnitude (speed) is constant. Its motion is in a closed circular path.
