Force & Net Force

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is net force?

Back

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

Front

What is balanced force?

Back

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

Front

What is unbalanced force?

Back

Forces that are not equal and opposite, causing a change in motion.

Front

If an object has a net force of 0N, what can we say about its motion?

Back

The object is either at rest or moving at a constant speed.

Front

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

Back

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

Front

What is an example of balanced forces in everyday life?

Back

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

Front

How does direction affect net force?

Back

Forces in the same direction add together, while forces in opposite directions subtract from each other.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
