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 does it mean if the net force is 0N?

Back

The object is in a state of equilibrium, meaning it is either at rest or moving at a constant speed.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, causing a change in the motion of an object.

Front

If an object is at rest and the net force is 0N, what can we say about the forces acting on it?

Back

The forces acting on the object are balanced.

Front

What happens to an object when unbalanced forces act on it?

Back

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

Front

How does changing direction affect the forces on a moving object?

Back

Changing direction involves unbalanced forces, even if the speed remains constant.

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.
