**What Happens if Two Forces Act in Opposite Directions on an Object**

When two forces act in opposite directions on an object, several outcomes can occur depending on the magnitude and direction of the forces. Let's explore these possibilities:

**1. Balanced Forces:**
- If the two forces are equal in magnitude and opposite in direction, they are considered balanced forces.
- Balanced forces result in no change in the object's motion.
- The object will either remain at rest if it was initially stationary, or it will continue to move at a constant velocity if it was already in motion.
- This is governed by Newton's First Law of Motion, which states that an object will remain in its state of motion (either at rest or moving with constant velocity) unless acted upon by an unbalanced force.

**2. Unbalanced Forces:**
- If the two forces are unequal in magnitude or not directly opposite in direction, they are called unbalanced forces.
- Unbalanced forces result in a change in the object's motion.
- The object will accelerate in the direction of the larger force.
- The acceleration can be determined using Newton's Second Law of Motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (a = F_net/m).

**3. Net Force Calculation:**
- To determine the net force acting on the object, subtract the magnitude of the smaller force from the magnitude of the larger force.
- The direction of the net force will be in the direction of the larger force.
- The net force will determine the acceleration of the object, as explained earlier.

**4. Examples:**
- If a car is being pushed forward by a force of 1000 N and experiencing a resistance force of 800 N in the opposite direction, the net force would be 1000 N - 800 N = 200 N in the forward direction. The car would accelerate forward due to this net force.
- Conversely, if the car is being pushed backward by a force of 1000 N and experiencing a resistance force of 1200 N in the forward direction, the net force would be 1000 N - 1200 N = -200 N in the backward direction. The car would decelerate or move in the opposite direction due to this net force.

In summary, when two forces act in opposite directions on an object, whether they are balanced or unbalanced will determine the resulting motion of the object. Balanced forces lead to no change in motion, while unbalanced forces cause acceleration in the direction of the larger force. The net force can be calculated by subtracting the magnitude of the smaller force from the magnitude of the larger force.

That's true. they cancel their power of force because they act from the opposite direction .
