Acceleration is the rate of change of velocity. It is a vector quantity, so it has both magnitude and direction. The SI unit for acceleration is meters per second squared (m/s2). There are two ways to find acceleration from the net force. The first way is to use the equation a = F/m, where F is the net force and m is the mass of the object. The second way is to use the equation a = v/t, where v is the final velocity and t is the time it takes to reach that velocity. To find acceleration using the equation a = F/m, first find the net force acting on an object. This can be done by adding up all of the forces acting on the object. Once you have found the net force, divide it by the mass of the object.
