Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object that are equal in size and 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 opposite in direction, causing a change in the motion of an object.

Front

What is net force?

Back

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

Front

If the net force is 0 N, what can we say about the forces acting on the object?

Back

The forces acting on the object are balanced.

Front

If an object is moving to the right, what can we infer about the forces acting on it?

Back

The forces acting on the object are unbalanced, with a greater force pushing it to the right.

Front

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

Back

The object will remain at rest.

Front

What happens to an object in motion when unbalanced forces act on it?

Back

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

Give an example of balanced forces in everyday life.

Back

A book resting on a table is an example of balanced forces; the weight of the book is balanced by the upward force of the table.

Give an example of unbalanced forces in everyday life.

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 effect of unbalanced forces on an object's speed?

Back

Unbalanced forces can increase or decrease an object's speed.
