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

How do balanced forces affect the motion of an object?

Back

Balanced forces do not change the motion of an object; it will either remain at rest or continue moving at a constant speed.

Front

How do unbalanced forces affect the motion of an object?

Back

Unbalanced forces cause an object to accelerate, change direction, or change speed.

Front

What happens in a tug of war when both teams pull with equal force?

Back

Front

If an object is at rest and the forces acting on it are balanced, what will happen?

Back

The object will remain at rest.

Front

If an object is moving and the forces acting on it are balanced, what will happen?

Back

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

Give an example of unbalanced forces in everyday life.

Back

A soccer ball being kicked is an example of unbalanced forces; the force of the kick is greater than the opposing forces.

Front

What is the net force when forces are balanced?

Back

The net force is zero when forces are balanced.
