Balanced & Unbalanced Forces

Front

What is a balanced force?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces occur when two or more forces acting on an object do not cancel each other out, causing the object to move.

Front

What force pulls objects towards the Earth?

Back

Gravity is the force that pulls objects towards the Earth.

Front

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

Back

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

Front

What happens to an object when unbalanced forces act on it?

Back

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

Front

What is an example of a balanced force?

Back

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

Front

What is an example of an unbalanced force?

Back

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

Front

What is the direction of the force of gravity?

Back

The force of gravity always pulls objects downward towards the center of the Earth.

Front

What can change the direction of a moving object?

Back

Forces can change the direction of a moving object, such as pushing or pulling it.

Front

What is the role of air pressure in forces?

Back

Air pressure can exert a force on objects, but it is usually not strong enough to overcome gravity unless in specific situations like a balloon.
