Balanced and Unbalanced Forces 24

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object's motion to change. They result in a net force that is not zero.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in a net force of 0 N, meaning the object's motion does not change.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined. It determines whether an object will move or remain at rest.

Front

How can you tell if an object is balanced?

Back

An object is balanced if the net force acting on it is 0 N.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

Give an example of an unbalanced force.

Back

A soccer ball being kicked down the field is an example of an unbalanced force.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion, and it can affect whether forces are balanced or unbalanced.

Front

What is 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.

Front

What does it mean if an object is accelerating?

Back

If an object is accelerating, it means that the net force acting on it is unbalanced, causing a change in its speed or direction.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, and it can contribute to unbalanced forces when an object is in free fall.
