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 two 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 overall force acting on an object after all the individual forces are combined.

Front

If the net force is 0 N, how will the object move?

Back

The object will not move.

Front

If the net force is greater than 0 N, what will happen to the object?

Back

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

Front

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

Back

The object remains at rest.

Front

What happens to a moving object when balanced forces act on it?

Back

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

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.

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.

Front

What is an example of unbalanced forces in everyday life?

Back

A soccer ball being kicked experiences unbalanced forces: the force of the kick is greater than the friction and air resistance.
