Balanced forces are forces where the effect of one force is cancelled out by another. A tug of war, where each team is pulling equally on the rope, is an example of balanced forces.

But what exactly is meant by the phrase unbalanced force? What is an unbalanced force? In pursuit of an answer, we will first consider a physics book at rest on a tabletop. There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes r...
Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not acce...
Consider another example involving balanced forces - a person standing on the floor. There are two forces acting upon the person. The force of gravity exerts a downward force. The floor exerts an upward force. Now consider a book sliding from left to right across a tabletop. Sometime in the prior history of the book, it may have been given a shove ...
The force of gravity pulling downward and the force of the table pushing upwards on the book are of equal magnitude and opposite directions. These two forces balance each other. Yet there is no force present to balance the force of friction. As the book moves to the right, friction acts to the left to slow the book down. There is an unbalanced forc...
To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction. If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanc...
When the forces applied to an object are unbalanced, the net force is not equal to zero. Unbalanced forces will change the velocity of the object—it will speed up, slow down, or change direction. The motion of the rope in the example given above is the result of unbalanced forces.
Slide deck. Download slide deck. Lesson details. Key learning points. Two forces of equal size, acting in opposite directions on an object, are balanced. The resultant force is the sum of the forces acting on the object, taking into account their direction. When forces are balanced there is no resultant force and no change in speed.
Mar 31, 2023 · Unbalanced forces change the motion of an object. This happens in two ways. If an object is at rest and an unbalanced force pushes or pulls the object, it will move. Unbalanced forces can also change the speed or direction of an object that is already in motion.
- A force is a push or a pull. A force has both strength and direction. Forces cause objects to change their motion.
- Balanced forces. Gravity is pulling the student down and the chair is pushing the student up with equal force, resulting in no motion.
- The ball is in motion. The forces acting on the ball are unbalanced (Gravity is pulling it down).
- Both sides need to be pulling with the same amount of force in opposite directions for the forces to be balanced.
- Izzy hit the ball too hard. He used too much STRENGTH when applying a force.
- In Zoe’s first attempt she used the right amount of STRENGTH when applying a force to the ball, but did not know the right direction because she wa...
- When Zoe pulled with a lot of force while Izzy wasn’t pulling at all, the strength of the force was greater in Zoe’s direction. That made Izzy move...
- Before Dr. Jeff cut the rope, the forces were balanced. The force from Izzy pulling in one direction was cancelled out by the force of Zoe pulling...
- The moving air from the hair dryer pushes the ball upward and the force of gravity pulls the ball downward with a force that is equal and opposite....
- Zoe’s hovercraft only moved in one direction. The force pushed her forward. If she wanted to stop, she needed to apply an equal force in the opposi...
Apr 29, 2022 · The free STEM lessons and activities below help students explore Newton's laws of motion and discover how these laws explain how an object in motion or at rest behaves and what happens when an unbalanced force is applied to an object.
