Balanced and UnBalanced Forces

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 a change in motion.

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 accelerates in the direction of the net force.

Front

How do you calculate net force when forces are in the same direction?

Back

You add the forces together.

Front

How do you calculate net force when forces are in opposite directions?

Back

You subtract the smaller force from the larger force.

Front

What is the net force when two equal forces of 50 N act in opposite directions?

Back

0 N balanced.

Front

What is the net force when a 30 N force acts to the right and a 10 N force acts to the left?

Back

20 N unbalanced to the right.

Front

What is the characteristic of a balanced force?

Back

A balanced force has a net force of zero.

Front

What is the characteristic of an unbalanced force?

Back

An unbalanced force causes a change in motion.
