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 but 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 when all the individual forces are combined. It determines the object's acceleration.

Front

If two people are pushing a car with equal force in opposite directions, what is the net force?

Back

The net force is zero, and the car will not move.

Front

What happens when the net force on an object is not zero?

Back

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

Example of balanced forces in everyday life?

Back

A book resting on a table experiences balanced forces: the weight of the book downward and the normal force of the table upward are equal.

Front

Example of unbalanced forces in everyday life?

Back

A soccer ball being kicked experiences unbalanced forces, causing it to move in the direction of the kick.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

How does friction affect motion?

Back

Friction can slow down or stop the motion of an object, depending on the surfaces in contact and the amount of force applied.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the object's mass.
