Net Forces

Front

What is a net force?

Back

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

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when the net force is zero, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Forces are unbalanced when the net force is not zero, causing a change in motion.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their directions.

Front

If two forces of 5 N to the right and 3 N to the left are acting on an object, what is the net force?

Back

The net force is 2 N to the right.

Front

What happens to an object at rest when balanced forces act on it?

Back

The object remains at rest.

Front

What happens to a moving 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 a balanced force in everyday life?

Back

A book resting on a table is an example of balanced forces; the weight of the book is balanced by the upward force of the table.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked is an example of an unbalanced force, as it accelerates in the direction of the kick.
