Explanation:

Speed is a scalar, while velocity is a vector with speed and direction. Acceleration is the rate of change of velocity. To calculate it, divide the change in velocity (found by subtracting initial from final velocity) by the time - interval. When an object slows down, acceleration is negative; when it speeds up, acceleration is positive. Velocity has units of meters per second (m/s), time has units of seconds (s), and acceleration has units of meters per second squared (m/s²).

Answer:

Speed is the rate of motion of an object. Velocity describes an object's speed and direction. The velocity of an object can change even if the speed of the object remains constant. This would occur if the direction of the object's motion changes.
The rate of change of velocity is called acceleration. The size of an acceleration depends on both the change in velocity and the time - interval of the change.
To calculate acceleration, divide the change in velocity by the time interval. To find the change in velocity, subtract the initial velocity ($v_i$) from the final velocity ($v_f$). The equation for average acceleration is $a=\frac{v_f - v_i}{t}=\frac{\Delta v}{t}$.
Final velocity will be less than initial velocity if an object is slowing down, and acceleration will have a negative value. Final velocity will be greater than initial velocity if an object is increasing speed, and acceleration will have a positive value.
The units for velocity are meters per second (m/s). The unit for time is seconds(s). Therefore, the units for acceleration are meters per second squared (m/s²).
