Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, causing a change in motion.

Front

What is net force?

Back

The overall force acting on an object, calculated by combining all individual forces.

Front

If a dog pulls on a toy with a force of 10 N to the right and another dog pulls with 10 N to the left, what is the net force?

Back

0 N (balanced forces).

Front

What is friction?

Back

A force that resists the motion of two surfaces that are pressed together.

Front

How does friction affect motion?

Back

Friction opposes motion, making it harder for objects to slide past each other.

Front

What happens when two people pull on a rope with equal force?

Back

The forces are balanced, and the rope does not move.

Front

If you push a box with 35 N to the right and your friend pushes with 25 N to the right, what is the net force?

Back

60 N unbalanced to the right.

Front

What is the effect of unbalanced forces on an object?

Back

They cause the object to accelerate in the direction of the greater force.

Front

What is an example of balanced forces in everyday life?

Back

A book resting on a table, where the force of gravity is balanced by the normal force from the table.
