You are investigating the relationship between force and acceleration. Which of the following would NOT be a suitable hypothesis? when the force decreases from 5N to IN,the acceleration should drop from 5m/s/s to 1m/s/s all forces produce an acceleration in an object's motion as the force doubles then the acceleration will also double

## Step 1To determine which hypothesis is not suitable, we need to understand the relationship between force and acceleration according to Newton's second law of motion. Newton's second law states that , where is the force applied to an object, is the mass of the object, and is the acceleration of the object.## Step 2Let's analyze each hypothesis in the context of Newton's second law:1. **When the force decreases from 5N to 1N, the acceleration should drop from to **: - This hypothesis implies a direct relationship between force and acceleration, which is consistent with Newton's second law. If the force decreases by a factor of 5, the acceleration should also decrease by a factor of 5, assuming mass remains constant.2. **All forces produce an acceleration in an object's motion**: - This hypothesis is not accurate. A force will produce acceleration only if it is unbalanced. If the forces are balanced (net force is zero), there will be no acceleration.3. **As the force increases, the acceleration will also increase**: - This hypothesis is consistent with Newton's second law. If the force increases and the mass remains constant, the acceleration will also increase proportionally.4. **As the force doubles, the acceleration will also double**: - This hypothesis is also consistent with Newton's second law. If the force doubles and the mass remains constant, the acceleration will double.## Step 3Based on the analysis, the hypothesis that does not align with the principles of Newton's second law is:- **All forces produce an acceleration in an object's motion**This is because not all forces produce acceleration; only unbalanced forces do.
