Several motorboat with the same mass used in an experiment the forces of the different motors versus their accelerations are are graphed what is the y-intercept of this graph
The y-intercept of the graph represents the force applied by the motor when the acceleration is zero.
Since the boats have the same mass, the force required to accelerate each boat from rest is the same. Therefore, the y-intercept of the graph would be the force applied by the motor to overcome the static friction and set the boat in motion, typically referred to as the static force or the force of friction.
If the graph is a straight line, the y-intercept would be the value of force when acceleration is zero.
