Objects of different masses fall with the same acceleration. This is because the acceleration due to gravity on the surface of the Earth is constant (in an ideal model) which equals 9.81 m/s^2. If you dropped a ten ton weight and a golf ball from a tower, they would hit the floor at the same time (not taking into account air resistance). However the force on the objects will be different. The larger the mass, the larger the force due to gravity.
