Balanced and Unbalanced forces

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when the total force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

What is the resultant force?

Back

The resultant force is the single force that represents the vector sum of all the individual forces acting on an object.

Front

How do you resolve a force into its components?

Back

To resolve a force into its components, use trigonometric functions: the horizontal component is found using cosine, and the vertical component is found using sine.

Front

What is the role of trigonometric functions in force resolution?

Back

Trigonometric functions, such as sine and cosine, are used to calculate the components of a force acting at an angle.

Front

What is an equilibrant force?

Back

An equilibrant force is a force that is equal in magnitude and opposite in direction to the resultant force, bringing the system into equilibrium.

Front

What is the significance of a force table in experiments?

Back

A force table is used to study the effects of multiple forces acting on an object and to visualize the concept of equilibrium.

Front

What are some limitations of using a force table?

Back

Limitations include inability to account for friction, air resistance, and the constraints of the pulley system.

Front

How do you calculate the magnitude of the resultant force from two forces at an angle?

Back

Use the formula: R = √(F1² + F2² + 2*F1*F2*cos(θ)), where F1 and F2 are the magnitudes of the forces and θ is the angle between them.

Front

What happens to an object when unbalanced forces act on it?

Back

When unbalanced forces act on an object, it will accelerate in the direction of the net force.
