Unbalanced forces are all around us and are important in our daily lives. Here are some simple examples to help explain this idea:
When a driver presses the gas pedal, the car's engine produces more force than the forces that try to slow it down, like friction and wind. This difference in force makes the car speed up.
For example, if the engine creates a force of 2000 N and friction pushes back with 1500 N, the total force moving the car forward is (2000 N - 1500 N = 500 N). This extra force makes the car go faster.
Think about a piece of fruit falling from a tree. At first, gravity pulls it straight down. While it falls, gravity is the only force acting on it until it hits the ground. The weight of the fruit is stronger than the air pushing against it, so it accelerates downwards until it lands.
When you push a shopping cart, the force from your push is stronger than the friction between the wheels and the ground. If you push with a force of 100 N and friction pushes back with 30 N, the total force moving the cart forward is (100 N - 30 N = 70 N). This net force makes the cart speed up.
In sports, unbalanced forces are very important. For instance, when a player kicks a soccer ball, the kick provides more force than gravity and air resistance pushing against the ball. This difference means the ball accelerates toward the goal.
These examples help us see how unbalanced forces help us understand how things move and speed up in everyday situations.
