Question

Which of the following best describes the forces when there are different-sized forces from opposite directions acting on an object?

Positive
Negative
Unbalanced
Gravitational

Answer 1

Unbalanced force

Step-by-step explanation:

When several forces are acting on an object from different directions such that the all the forces are of different magnitudes and all forces have different directions

Then in that case the sum of all forces on the object will be given by vector sum of all forces on it

so here we will have net force on the system is unbalanced as all the forces are of different magnitudes

so in that case we can say

`F_(net) = \vec F_1 + \vec F_2 + \vec F_3 .........`

so sum of all above forces is non zero so it is known as unbalanced forces

Answer 2

When the forces are added together incorporating the negative and positive signs by convention, the yield is the net force. When the forces have the same size, the net force is equal to zero. If they have different sizes, it will be non-zero. We cannot tell if the net force is positive or negative unless we know the actual values of the forces. What we know is that, the forces are unbalanced.
