Two aluminium spheres P and Q, of masses 0.50 kg and 1.0 kg respectively, are released at the same time from the same height.
Why do they have the same acceleration?

The two aluminium spheres have the same acceleration because they are subject to the same force of gravity. According to Newton's second law of motion, F=ma, where F is the force, m is the mass, and a is the acceleration. Thus, the force of gravity acting on both spheres is the same, since their masses are different (0.50 kg for P and 1.0 kg for Q). Therefore, since force is equal for both spheres, their accelerations (a) must also be equal.
