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 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 greater force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

On which surface would friction be the greatest?

Back

Carpet has the greatest friction compared to ice, snow, and water.

Front

What is net force?

Back

Net force is the sum of all forces acting on an object, determining its motion.

Front

If two people push a chair with equal force in opposite directions, what happens?

Back

The chair doesn't move because the forces are balanced.

Front

What happens to an object at rest when the net force is zero?

Back

The object remains at rest.

Front

What happens to an object in motion when the net force is zero?

Back

The object continues to move at a constant speed in a straight line.

Front

How does increasing friction affect motion?

Back

Increasing friction makes it harder for an object to move.

Front

What is an example of an unbalanced force in everyday life?

Back

A person pushing a shopping cart while another person pulls it in the opposite direction.
