Uniform acceleration is a type of motion where an object's velocity changes at a constant rate. This means that the object's speed increases or decreases by the same amount over equal intervals of time.
The formula for uniform acceleration is:
a = (vf - vi) / t
where a is the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time interval.
To solve for initial velocity, you can rearrange the formula for uniform acceleration as:
vi = vf - at
where vi is the initial velocity, vf is the final velocity, a is the acceleration, and t is the time interval.
The units for acceleration are typically meters per second squared (m/s^2). However, depending on the units used for velocity and time, other units such as kilometers per hour squared (km/h^2) or feet per second squared (ft/s^2) may also be used.
Yes, uniform acceleration can be negative. This indicates that the object is slowing down, since the final velocity is smaller than the initial velocity. A positive acceleration indicates that the object is speeding up.
