Balanced and Unbalanced Forces OL

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 occur when two or more forces acting on an object do not cancel each other out, causing the object to accelerate in the direction of the net force.

Front

Why does a book on a table not move?

Back

The forces of the table pushing up and gravity pulling down are balanced.

Front

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

Back

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

Front

What is an example of balanced forces?

Back

A book resting on a table, where 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?

Back

A car accelerating around a mountain curve, where the force of the engine is greater than the frictional force.

Front

How can you tell if forces are balanced?

Back

If the object remains at rest or moves at a constant speed in a straight line, the forces are balanced.

Front

What is the net force?

Back

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

Front

What does it mean if an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, meaning all forces are balanced.

Front

What is inertia?

Back

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