Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

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

Front

How do unbalanced forces affect an object's motion?

Back

Unbalanced forces cause an object to accelerate in the direction of the greater force.

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 in a straight line.

Front

Give an example of balanced forces.

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.

Front

Give an example of unbalanced forces.

Back

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

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined.

Front

If two forces of 5 N and 3 N act in the same direction, what is the net force?

Back

The net force is 8 N in the direction of the forces.

Front

If a 10 N force pulls an object to the right and a 10 N force pulls it to the left, what is the net force?

Back

The net force is 0 N, resulting in balanced forces.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
