Balanced and Unbalanced Forces

Front

What are balanced forces?

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 are unbalanced forces?

Back

Unbalanced forces are forces that do not cancel each other out, causing an object to change its motion.

Front

Example of balanced forces: A book resting on a table. What happens to the book?

Back

The book stays at rest because the forces acting on it are balanced.

Front

Example of unbalanced forces: A soccer ball being kicked. What happens to the ball?

Back

The ball moves in the direction of the kick because the forces are unbalanced.

Front

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

Back

It starts to move in the direction of the unbalanced force.

Front

What happens to a moving object when unbalanced forces act on it?

Back

It changes direction or speed depending on the direction of the unbalanced force.

Front

What is the net force?

Back

The net force is the total force acting on an object after all the forces are combined.

Front

If two people push a car in the same direction with equal force, what type of force is this?

Back

This is an example of balanced forces.

Front

If one person pushes a car to the right with a force of 10 N and another person pushes to the left with a force of 5 N, what is the net force?

Back

The net force is 5 N to the right.

Front

What is inertia?

Back

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