Fiction is harmful, because it can save a lot of energy. Waste lot of unrecyclable energy is scurviness.

WOW!

Friction is more helpful because it can prevent cars from sliding on ice and crashing into others. Low friction causes cars to slide and BOOM!!! Friction on shoes can help us to climb up slopes cuz they stop us from sliding down. Finally, fluid friction of air made parachutes possible. Fluid friction of water made boating and swimming harder so there are sports games to watch.

WOW!

I think friction is most harmful, is because friction will cause harder to perform. For example, when people are riding bike if the road have friction people will go hardly--MandySun

I think friction is extremely helpful because it helps things stay in place. Some examples include walking on the ground, riding a bicycle, and so on. Without friction, the world will be a mess, everything sliding around. Although friction might seem like a small thing, it's an essential part of our everyday lives. -Jessica

friction is most harmful because if we are riding bicycle and we fell down it will hurt us a lot because the friction

friction increase is Harmful

MOST harmful because:

1.When we are pushing / pulling heavy things, it's hard for us to move and we need more force applied.

2.The thing may be applied too much force but fiction too much. It will be flipped over to another face down.

Reducing it helps machines run efficiently and objects move smoothly. Reducing the friction associated with good behaviors makes them easier to perform and increasing the friction associated with bad behaviors makes them harder to do

# data[].attributes.body
I think it beneficial,because it can Reduce thoughts of falling if there is a car running.

# data[].attributes.body
Friction is mostly helpful, because it can help movement and control. For example, friction is used in brakes to slow bikes and in parachutes to slow people during falling.

# data[].attributes.body
Friction is more harmful because friction can cause the waste of energy while two things rub with each other.

I think reducing the friction is beneficial because it is associated with good behaviors makes them easier to perform and increasing the friction associated with bad behaviors makes them harder to do.

Friction is most harmful, because by reducing friction associated with a habit, we increase the chances of making it a part of our daily routine.

Friction is most harmful, because if you put sand on an icy sidewalk increases friction, so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out.

Friction is most helpful because the ventricles that we used today, car, is using the friction. We can use wheels to transport an object by using friction.

Friction is most harmful because if people fall when they are running, then they might break their knees.

# data[].attributes.body
Friction is most harmful because friction reduces the efficiency of mechanical systems and causes wear. The system must expend more energy to overcome friction.

Friction is most harmful, because it wastes energy and creates unwanted heat. This can lead to bending or wearing down of materials. As a result, the products you create may not last as long and could end up costing more money.
