If 2 blocks have the same mass which one has the greater acceleration?

To determine which block has the greater acceleration, we need more information. The acceleration of an object depends not only on its mass but also on the applied force or net force acting on it. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force applied and inversely proportional to its mass.

F = ma

Where:
F is the net force applied to the object,
m is the mass of the object, and
a is the acceleration of the object.

If two blocks have the same mass, the one with the greater net force acting on it will have the greater acceleration. The net force can come from pushes, pulls, or any other external force applied to the object.

Therefore, if the two blocks experience the same force, they will have the same acceleration. But if one block has a greater net force acting on it than the other, it will have the greater acceleration, assuming their masses are the same.
