Balanced and Unbalanced Forces Review Bell Ringer

Front

What is a balanced force?

Back

A balanced force occurs when the net force acting on an object is zero, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, 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

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What is net force?

Back

Net force is the sum of all forces acting on an object, taking into account their directions.

Front

What is an example of a contact force?

Back

An applied force, such as pushing a box, is an example of a contact force.

Front

What is an example of a non-contact force?

Back

Gravity is an example of a non-contact force, as it acts at a distance.

Front

How do you determine the direction of net force?

Back

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

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to start moving, stop moving, or change direction.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, making it harder to change its motion.
