Friction is a force produced between two surfaces when one object rubs against the other. Friction always works against the motion. The lesson below, friction for kids, teaches about the science behind the force of friction.
Friction is the force produced between two surfaces when they are rubbing or sliding against each other.
The force of friction always works in the opposite direction to the movement.
So, friction occurs when two surfaces stick to each other a little.
Friction always slows a moving object down, because it tries to stop the surfaces from sliding over one another.
Where do you think, you can walk easily? On a rough surface or a smooth surface?
If you are unsure about your answer, let’s ask the question in a different way.
Where do you think you can walk easily? On the road or on ice?
The answer will obviously be on the road. Now if you think about these two surfaces; the surface of the road is rough whereas the surface of ice is smooth.
