Different amounts of force are applied to the same boat over several trials, and the acceleration is measured. In a graph of acceleration versus net force, what does the slope of the graph represent? (1 point)
the inverse of the speed of the boat the
the mass of the boat
the inverse of the mass of the boat
the speed of the boat
The slope of the graph represents the mass of the boat.
Several motorboats with the same mass are used in an experiment. The forces of the different motors versus their accelerations are graphed. What is the y-intercept of this graph? (1 point) Responses
the inverse of the mass
zero
the mass
the velocity
The y-intercept of the graph represents the force when the acceleration is zero, which is also known as the "baseline force" or "initial force" required to overcome friction and other resistive forces. In this case, the y-intercept would typically be zero.
Which situation describes an object that is accelerating?(1 point) Responses
when the velocity is constant
when the velocity increases
when the net force is zero
when equal forces act simultaneously
