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 occur when two or more forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

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

Back

When balanced forces act on an object, it remains at rest or continues to move at a constant speed in a straight line.

Front

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

Back

When unbalanced forces act on an object, it will accelerate, change direction, or change its speed.

Front

What is net force?

Back

Net force is the overall force acting on an object after 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

If the net force is 0 N, the forces acting on the object are balanced.

Front

If an object is not moving, what can we infer about the forces acting on it?

Back

If an object is not moving, the forces acting upon it are balanced.

Front

What is an example of balanced forces in everyday life?

Back

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

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is pushing a swing; the force you apply causes the swing to move.

Front

How do you determine the direction of net force?

Back

The direction of net force is determined by the direction of the larger force when forces are unbalanced.
