Emily uses a rifle to shoot a bullet at a target. The bullet has a mass of 13 grams. The rifle has a mass of 3,500 grams. When she shoots, the bullet accelerates 850 m/s2. According to Newton’s third law of motion, the bullet is exerting the same force on the rifle. Why doesn’t the rifle accelerate 850 m/s2?
Assuming a constant force, if the mass of an object increases, the acceleration of the object will . Assuming a constant force, if the mass of an object decreases, the acceleration of the object will .
If the force applied to an object increases, the acceleration will .
If the force applied to an object decreases, the acceleration will .
