When unbalanced forces push or pull on an object, some interesting things happen. These changes can be understood using Newton's Second Law of Motion.
This law tells us that how fast an object speeds up, or its acceleration, is connected to the total force acting on it and its mass. It can be summed up by this simple equation:
Net Force = Mass × Acceleration
(Or, in symbols: ( F_{net} = m \cdot a ))
Here are some effects of unbalanced forces:
Change in Motion: When unbalanced forces act on an object, it will start moving in the direction of the net force. For instance, if you push a box harder than the friction holding it back, the box will slide forward.
Calculating Acceleration: To figure out how fast something speeds up, you can use the net force and the mass. For example, if a force of 10 Newtons pushes a 2-kilogram object, we would calculate the acceleration like this:
Acceleration = Net Force ÷ Mass
Or, in numbers:
( a = \frac{10 , \text{N}}{2 , \text{kg}} = 5 , \text{m/s}^2 ).
Direction Matters: The direction in which the object speeds up is the same as the direction of the net force acting on it.
Change in Speed: The object's speed can go up or down. If the unbalanced force pushes in the same way the object is moving, it speeds up. If it pushes against the motion, it slows down.
Understanding these ideas helps us figure out how things move in our everyday lives.
