1.Check the steel windows in your classroom or at home. Close and open them frequently and observe if you can move them easily. If you can move them easily. If you find difficulty in opening or closing them, you need to reduce the friction. What should you do to make them easier to open and close?
2.Go around your house and check the stairs and floor. See if they are safe. Do something if you find that they are not safe due to effects of friction. List down some hazards you observed.
3.List activities that you and others do where friction is useful. Identify if the friction has been reduced or increased in the activity.
4.A man wants to use the smallest force he can do to push a heavy box. Where should he put the box?
5.Why is it easier to travel on a cemented road than a rough road?

Answer:
1. Add an oil to the steel window to reduce friction.
2. Slips
Slips happen where there is too little friction or traction between the footwear and the walking surface. Common causes of slips are:
wet or oily surfaces
occasional spills
weather hazards
3. One of the most obvious effects of friction for students is that it can lead to the gradual wearing away of things this can be seen in examples like the uneven soles of our shoes, balding bicycle tires and the deliberate action of rubbing sandpaper on a surface
4. For instance, friction is the force that keeps a box from sliding across the floor when it is pushed.
5. A concrete road is much smoother than uneven and rough road. Friction on concrete road is less as compared to a rough road, Thus, It's easier to ride a bicycle on a concrete road than on an uneven, rough road
