Question
When the net force on an object is non-zero, the forces on the object are called ___.
- Balanced forces
- Unbalanced forces
- Contact forces
- Gravitational forces
Hint:
Forces are not equal and opposite. So, net force will not be equal to zero.
The correct answer is: Unbalanced forces
- An object is said to be acted upon by an unbalanced force, when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
- Unequal forces are there, they don't cancel out each other.
- Means net force will not be equal to zero.
- So, the correct option is b.
An unbalanced force causes a change in motion, speed, direction, or movements because of unequal force or strength that is applied to one side of an object.
