TEKS:8.6A Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal in size, causing a change in motion of an object.

Front

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

Back

The object does not change its state of motion; it remains at rest or continues to move at a constant speed.

Front

What is the net force when balanced forces are acting on an object?

Back

The net force is zero.

Front

What is an example of balanced forces?

Back

A book resting on a table, where the force of gravity is balanced by the normal force of the table.

Front

What is an example of unbalanced forces?

Back

A soccer ball being kicked, where the force of the kick is greater than the friction opposing it.

Front

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

Back

The forces are balanced.

Front

What does it mean if an object is in motion and the forces acting on it are balanced?

Back

It means the object is moving at a constant speed in a straight line.

Front

What is the effect of unbalanced forces on an object?

Back

They cause the object to accelerate, decelerate, or change direction.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object.
