In the context of a graph that plots the force of the motors versus their accelerations, according to Newton's second law of motion (F = ma), the graph can be interpreted in terms of Y = mx + b, where:
- F (force) is on the y-axis,
- a (acceleration) is on the x-axis,
- m (mass) is the slope of the line.
If we rearrange the equation to F = ma, we see that when acceleration (a) is zero, the force (F) will also be zero if the system is at rest. Therefore, the y-intercept of the graph, which represents the value of force when acceleration is zero, is:
**Zero.**
So, the correct answer is **zero**.
- F (force) is on the y-axis,
- a (acceleration) is on the x-axis,
- m (mass) is the slope of the line.
