Which of these changes will decrease the acceleration of an object? Select the two correct answers.(1 point)
increasing its mass
decreasing its mass
decreasing the applied net force
increasing the applied net force
Part A and C will decrease the acceleration.
To determine which changes will decrease the acceleration of an object, we need to understand the factors that affect acceleration. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
1. Increasing its mass: Increasing the mass of an object will decrease its acceleration. This is because the greater the mass, the more inertia the object has and the harder it is to accelerate. Therefore, increasing the mass will decrease the acceleration.
2. Decreasing the applied net force: Decreasing the net force acting on an object will also decrease its acceleration. This is because the net force determines the rate at which the object's velocity changes. If the net force is reduced, there will be less force available to accelerate the object, resulting in a decrease in acceleration.
On the other hand, decreasing the mass of an object will actually increase its acceleration, as it becomes easier to accelerate. Likewise, increasing the applied net force will also increase the acceleration, as there is more force available to change the object's velocity.
Therefore, the two correct options that will decrease the acceleration of an object are:
- Increasing its mass
- Decreasing the applied net force
