Balanced and Unbalanced Forces

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but 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

What happens to an object when the net force is 0N?

Back

The object remains at rest or continues to move at a constant velocity; it does not accelerate.

Front

What is the unit of force?

Back

The unit of force is Newtons (N).

Front

Give an example of a balanced force.

Back

A boy standing still is an example of a balanced force.

Front

Give an example of an unbalanced force.

Back

A car accelerating forward is an example of an unbalanced force.

Front

What is the effect of balanced forces on a skydiver?

Back

If the force of gravity is balanced by air resistance, the skydiver moves down at a constant velocity.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F=ma). If the net force is unbalanced, the object will accelerate.

Front

What does it mean for forces to be in equilibrium?

Back

Forces are in equilibrium when they are balanced, resulting in no net force and no acceleration.

Front

How can you identify an unbalanced force in a scenario?

Back

An unbalanced force can be identified if an object is changing its speed or direction.
