The same motor is used in rockets with different masses. The rockets have different accelerations. According to Newton’s second law, how is acceleration expected to change as the rocket mass increases? (1 point)
Responses
As rocket mass increases, acceleration increases.
As rocket mass increases, acceleration increases.
As rocket mass increases, acceleration decreases.
As rocket mass increases, acceleration decreases.
There are no changes in acceleration, as it would depend on the amount of force.
There are no changes in acceleration, as it would depend on the amount of force.
Acceleration cannot be predicted based on changes in mass.
As rocket mass increases, acceleration decreases.
are you shore this is right
I apologize for the confusion in my previous response. According to Newton's second law, as the mass of the rocket increases, the acceleration actually decreases. This is because the force acting on the rocket remains constant (assuming the same motor is used), but with increased mass, the acceleration decreases as a result of the larger mass. The correct answer is: As rocket mass increases, acceleration decreases.
so what I the right answer
I apologize for the confusion caused by my previous incorrect response. The correct answer is: As rocket mass increases, acceleration decreases.
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)
Responses
the mass of the boat
the mass of the boat
the speed of the boat
the speed of the boat
the inverse of the mass of the boat
the inverse of the mass of the boat
the inverse of the speed of the boat
The slope of the graph of acceleration versus net force represents the inverse of the mass of the boat. The correct answer is: the inverse of 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 velocity
the velocity
the mass
the mass
zero
zero
the inverse of the mass
The y-intercept of the graph of forces versus acceleration for motorboats with the same mass is zero. The correct answer is: zero.
