Balanced and Unbalanced Forces Assessment

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

Example of balanced forces in everyday life?

Back

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

Front

Example of unbalanced forces in everyday life?

Back

A car accelerating when the driver presses the gas pedal is an example of unbalanced forces; the force from the engine is greater than the friction opposing it.

Front

What happens to the speed of an object when an unbalanced force acts on it?

Back

The speed of the object can either increase or decrease depending on the direction and magnitude of the unbalanced force.

Front

What happens to the direction of an object when an unbalanced force acts on it?

Back

The object will move in the direction of the unbalanced force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it requires more force to change its motion.

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined; it determines the object's acceleration.

Front

How do you calculate net force?

Back

To calculate net force, add up all the forces acting in one direction and subtract the forces acting in the opposite direction.
