you push a ball with a net force of 2 n and it accelerates. what happens if you exert 2 n of net force on an object that has 3 times the mass?
1. the object will accelerate the same amount as before because the mass does not affect the object’s acceleration.
2. the object will accelerate 1/3 as much because if you apply the same net force but increase the mass, the acceleration will decrease.
3. the object will not accelerate because now it is too heavy.
4. the object will accelerate 3 times as much because if you apply the same net force and increase the mass, the acceleration will increase.
