According to Newton’s second law, when the same force is applied to two objects of different masses,

the object with greater mass will experience a great acceleration, and the object with less

mass will experience an even greater acceleration.

the object with greater mass will experience a smaller acceleration, and the object with less mass will

experience a greater acceleration.

the object with greater mass will experience a small acceleration, and the object with less mass will experience even smaller acceleration
