Balanced and 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 motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What is net force?

Back

Net force is the sum of all forces acting on an object, taking into account their direction.

Front

What happens to an object when the net force is 0N?

Back

The object remains at rest or continues to move at a constant velocity.

Front

Give an example of balanced forces.

Back

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

Front

Give an example of unbalanced forces.

Back

A baseball that has been thrown to home plate is an example of unbalanced forces, as the force of the throw is greater than any opposing forces.

Front

How do balanced forces affect motion?

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 motion?

Back

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

Front

What is the direction of motion when forces are unbalanced?

Back

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

Front

What is the relationship between mass and force in unbalanced situations?

Back

In unbalanced situations, the greater the mass of an object, the greater the force needed to accelerate it.
