Balanced and Unbalanced forces

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

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

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

If the net force is 0 N, what can we say about the forces acting on the object?

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

Give an example of balanced forces in everyday life.

Back

A book resting on a table experiences balanced forces: the weight of the book downward is balanced by the normal force of the table upward.

Front

Give an example of unbalanced forces in everyday life.

Back

A soccer ball being kicked experiences unbalanced forces: the force of the kick is greater than the friction and air resistance acting against it.

Front

What is the effect of balanced forces on a moving object?

Back

If balanced forces act on a moving object, it will continue to move at a constant speed in a straight line.

Front

What is the effect of unbalanced forces on a stationary object?

Back

Unbalanced forces acting on a stationary object will cause it to start moving in the direction of the net force.

Front

How do you calculate net force?

Back

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