Balanced or Unbalanced?

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

Back

The object remains at rest because the balanced forces cancel each other out.

Front

What happens to an object in motion when balanced forces act on it?

Back

The object continues to move at a constant velocity because the balanced forces do not change its motion.

Front

What is the net force when forces are balanced?

Back

The net force is zero when forces are balanced.

Front

What is the net force when forces are unbalanced?

Back

The net force is greater than zero when forces are unbalanced, leading to acceleration.

Front

Give an example of balanced forces in everyday life.

Back

A book resting on a table experiences balanced forces: the weight of the book downward is balanced by the normal force of the table upward.

Give 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 acting against it.

Front

How do balanced forces affect the motion of an object?

Back

Balanced forces do not change the motion of an object; it either remains at rest or continues 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.
