Question

Which describes acceleration involving only a change in direction?

Answer 1

Acceleration involving only a change in direction occurs when the velocity changes in direction but not in magnitude.

Step-by-step explanation:

Acceleration is defined as a change in velocity, which can involve a change in magnitude, direction, or both. In the case of a change in direction only, such as when a car turns a corner, there is still an associated acceleration because the direction of the velocity is changing. This sideways acceleration is more noticeable with sharper curves and higher speeds. So, acceleration involving only a change in direction occurs when velocity changes in direction but not in magnitude.

Answer 2

If we consider any system moving with uniform circular motion we can notice that the MAGNITUDE of the accelaration remains constant. However, there is a change in the direction of the acceleration at every instant of time .

As the object moves through the circle the acceleration changes its direction always pointing to the center of the circle.
