Balanced/Unbalanced Forces

Front

What is a balanced force?

Back

A balanced force occurs when two 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 two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

Example of an unbalanced force: An airplane taking off.

Back

The force of the engines pushing the airplane forward is greater than the forces of gravity and air resistance, resulting in acceleration.

Front

Example of a balanced force: A lamp sitting on a table.

Back

The force of gravity pulling the lamp down is balanced by the normal force from the table pushing it up, resulting in no motion.

Front

What is net force?

Back

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

Front

If a net force of 400 N is acting downwards, what does this indicate?

Back

It indicates that the downward forces are greater than the upward forces, resulting in a downward acceleration.

Front

If two forces of 17 N and 3 N are acting in opposite directions, what is the net force?

Back

The net force is 14 N in the direction of the larger force.

Front

What happens when the net force is zero?

Back

When the net force is zero, the object is either at rest or moving at a constant velocity.

Front

Calculate the resultant force when 40 N is applied to the left and 40 N is applied to the right.

Back

The resultant force is 0 N, indicating balanced forces.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, change direction, or change shape.
