A balanced and unbalanced forces worksheet is a document or tool used to help students understand the concept of balanced and unbalanced forces and how they affect the motion of objects. It typically consists of a series of questions or problems that students must solve using their knowledge of these forces.

The worksheet may include problems that involve identifying the presence of balanced and unbalanced forces in different scenarios, calculating the net force acting on an object, and predicting the effect of balanced and unbalanced forces on the motion of an object.

Here is an example of a question that might be included on a balanced and unbalanced forces worksheet:

“A box sits on a table. Is there a net force acting on the box? Explain.”

To answer this question, students would need to consider the forces acting on the box, including the force of gravity pulling the box downward and the upward force exerted by the table on the box. They would then need to determine whether these forces are balanced or unbalanced. In this case, the forces are balanced because they are equal in magnitude and opposite in direction, so there is no net force acting on the box.

Overall, a balanced and unbalanced forces worksheet is a useful tool for helping students understand the concept of forces and how they affect the motion of objects.

### Answer

- A balanced force is a force that acts on an object and is balanced by an equal and opposite force. An unbalanced force is a force that acts on an object and is not balanced by an equal and opposite force.
- Balanced forces do not cause a change in the motion of an object. If an object is at rest, it will remain at rest, and if it is in motion, it will continue moving at a constant speed and in a straight line.
- Unbalanced forces cause a change in the motion of an object. If an object is at rest, it will be set in motion, and if it is in motion, its speed or direction will change.
- An example of a situation where there are balanced forces acting on an object is a book resting on a table. The force of gravity pulling the book downward is balanced by the upward force exerted by the table on the book.
- An example of a situation where there are unbalanced forces acting on an object is a person pushing a box across a floor. The force of the person pushing the box is greater than the friction force opposing the motion, so there is a net force acting on the box and it will accelerate.
- To calculate the net force acting on an object, you add up all of the forces acting on the object and find the resulting overall force. This can be done using the equation Fnet = F1 + F2 + F3 + …, where Fnet is the net force and F1, F2, F3, etc. are the individual forces.
- The relationship between mass and the acceleration of an object due to a net force is described by 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. This can be expressed as a = Fnet/m.
- Newton’s first law of motion states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant speed and in a straight line unless acted upon by an unbalanced force.
- The motion of an object cannot be changed by a balanced force because balanced forces do not cause a change in the motion of an object.
- The motion of an object can be changed by an unbalanced force because unbalanced forces cause a change in the motion of an object.
