Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object in opposite directions that are equal in size, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when two or more forces acting on an object are not equal, causing the object to move in the direction of the greater force.

Front

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

Back

When the net force on an object is zero, the object remains at rest or continues to move at a constant speed in a straight line.

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 chair with equal force in opposite directions, what is the net force?

Back

The net force is 0 N, and the chair does not move.

Front

What is an example of balanced forces in everyday life?

Back

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

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is when a soccer player kicks a ball; the force of the kick is greater than the friction, causing the ball to move.

Front

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

Back

An object at rest will start to move in the direction of the unbalanced force.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, giving them weight.

Front

How do action and reaction forces work?

Back

For every action force, there is an equal and opposite reaction force, as described by Newton's third law of motion.
