Balanced and Unbalanced Forces (Net Force)

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 two people push a couch with forces of 35 N and 25 N to the right, what is the net force?

Back

60 N to the right.

Front

What happens to an object when the net force is zero?

Back

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

Front

What is the net force when a 10 N force pushes right and a 10 N force pushes left?

Back

Net force is 0 N.

Front

If a 5 N force pushes right and a 2.5 N force pushes left, what is the net force?

Back

2.5 N to the right.

Front

What is the effect of unbalanced forces on an object?

Back

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

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 is an example of balanced forces in everyday life?

Back

A book resting on a table is an example of balanced forces; the force of gravity pulling it down is balanced by the normal force from the table pushing it up.
