Question
The combination of all the forces acting on a body is called ____. It is measured in the SI units of ____.
- Balanced force, m/s2
- Net force, N
- Unbalanced force, m/s2
- Net force, Nm
Hint:
If two forces act on an object in the same direction, the net force is the sum of the two forces.
The correct answer is: Net force, N
- The combination of all the force acting upon a body is known as net force.
- It is measured in the SI units of newton ( N ).
