Force & Net Force

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 start moving, stop moving, or change direction.

Front

If a force causes an object to start moving, stop moving, or change direction, what type of force is it?

Back

Unbalanced 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 the net force?

Back

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

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting in one direction and subtracting the forces acting in the opposite direction.

Front

What is an 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

What is an example of unbalanced forces in everyday life?

Back

Pushing a shopping cart forward is an example of unbalanced forces; the force you apply is greater than the friction opposing the motion.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass, commonly experienced as the weight of an object.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion between magnetic poles, which can cause objects to move without direct contact.
