The best description of the sum of all forces acting on an object is:
net force, which is a vector sum.
Net force is the overall force acting on an object when all individual forces are combined, and since forces have both magnitude and direction, it is considered a vector quantity.
To find the net force of the system, we can assign a negative value to the downward force (100 N), and the upward force will remain positive (150 N).
So:
Now, we can calculate the net force:
Net Force = Upward Force + Downward Force Net Force = 150 N + (-100 N) Net Force = 150 N - 100 N Net Force = 50 N
Thus, the net force of this system is 50 N.
To find the net force of this system, we will assign a negative value to the force moving to the right (the force exerted by the four ball) and keep the force exerted by the cue ball positive.
Now, we can calculate the net force:
Net Force = Force of Cue Ball + Force of Four Ball
Net Force = 70 N + (-50 N)
Net Force = 70 N - 50 N
Net Force = 20 N
Thus, the net force of this system is 20 N.
