This week, 3BC scientists have been stepping into the world of physics. We have been learning all about forces—pushes, pulls and friction. To see forces in action, we set up an investigation! We wanted to find out: How do different surfaces affect how much friction there is? Friction is the force that happens when two surfaces rub together. It acts like a brake, slowing things down. To test this, we used a very special scientific tool called a newton meter, which measures force in Newtons. What surface do you think created the most friction? A. Lino B. Carpet or C. Table Top.
