Balanced and Unbalanced Forces

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is net force?

Back

Net force is the sum of all forces acting on an object, determining its motion.

Front

If the net force on an object is 0 N, what can we say about the forces acting on it?

Back

The forces are balanced, and the object will not change its state of motion.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What happens to an object when an unbalanced force acts on it?

Back

The object will accelerate in the direction of the unbalanced force.

Front

If a 20 N force to the right and a 40 N force to the left are acting on an object, what is the net force?

Back

The net force is 20 N to the left.

Front

What is the effect of balanced forces on a stationary object?

Back

A stationary object will remain at rest if balanced forces act on it.

Front

What is the effect of unbalanced forces on a moving object?

Back

A moving object will change its speed or direction if unbalanced forces act on it.

Front

What is an example of balanced forces in everyday life?

Back

A book resting on a table experiences balanced forces: the weight of the book downward and the normal force of the table upward.
