Answer» What is acceleration?EXPLANATION:acceleration is the RATE of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as DESCRIBED by NEWTON's Second Law. The SI unit for acceleration is metre PER second squared.SI unit: m/s2, m·s−2, m s−2(B) 9,8 m/s |
