Balanced & Unbalanced Forces

Front

What is a balanced force?

Back

A balanced force occurs when two or more forces acting on an object are equal in size and opposite in direction, resulting in no change in the object's motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are unequal in size or not opposite in direction, causing the object to accelerate or change its motion.

Front

What happens to an object at rest when balanced forces act on it?

Back

The object remains at rest.

Front

What happens to an object in motion when balanced forces act on it?

Back

The object continues to move at a constant speed in a straight line.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

If two forces of 400 N are acting in opposite directions, what is the net force?

Back

0 N (the forces cancel each other out).

Front

If a 10 N force is applied to the right and a 7 N force is applied to the left, what is the net force?

Back

3 N Right.

Front

What is the effect of an unbalanced force on a stationary object?

Back

It causes the object to start moving.

Front

What is the effect of an unbalanced force on a moving object?

Back

It causes the object to accelerate, decelerate, or change direction.

Front

Give an example of balanced forces in everyday life.

Back

A book resting on a table is an example of balanced forces; the weight of the book is balanced by the upward force of the table.
