referred to as acceleration. Acceleration is a vector quantity that represents the rate at which an object's velocity is changing. It can be positive, negative, or zero, depending on whether an object is speeding up, slowing down, or maintaining a constant speed.
Acceleration can be calculated using the formula:
\[ a = \frac{v_f - v_i}{t} \]
where:
- \( a \) is the acceleration,
- \( v_f \) is the final velocity,
- \( v_i \) is the initial velocity, and
- \( t \) is the time taken for the change in velocity to occur.
A change in velocity or change in speed direction is
