Balanced and UnBalanced Forces

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction. They do not cause a change in the motion of an object.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or direction. They cause a change in the motion of an object.

Front

What does equilibrium mean in terms of forces?

Back

Equilibrium means that all the forces acting on an object are balanced, resulting in no net force and no change in motion.

Front

If an object is at rest and the forces acting on it are balanced, what will happen?

Back

The object will remain at rest.

Front

If an object is moving and the forces acting on it are unbalanced, what will happen?

Back

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

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined.

Front

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

Back

Add the magnitudes of the two forces together.

Front

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

Back

Subtract the smaller force from the larger force and take the direction of the larger force.

Front

What happens to an object if the net force is zero?

Back

If the net force is zero, the object will not accelerate; it will either remain at rest or continue moving at a constant speed.

Front

What is an example of balanced forces in everyday life?

Back

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