Are negative forces possible?
A 'negative' force is the opposite of what you choose to be the positive direction. Magnitude of a force is never negative but direction can be negative that is opposite direction.
Is negative normal force possible?
Correct answer:
Normal force is defined as the force that a surface exerts on an object. If the object is at rest, net force on the object is equal to zero; therefore, the downward force (weight) must be equal to the upward force (normal force). Since weight acts in the downward direction it will be negative.
Can force of impact be negative?
The size of a force is always positive. However, you can choose to measure the force in a particular direction and choose the positive and negative direction. In that case, the direction of the force dictates if it is positive or negative.
Can a reaction force be negative?
The answer is YES. We must bear in mind that force is a vector. Forces to the left are negative and forces downwards are also negative.
