Answer 1

1.It cause damage to tyres.

2.It burns any object entering earth atmosphere

Answer 2

1.  In machines the moving and rotating objects (wheels, shafts) get heated up and get worn out.  The life time of the tools is shortened.

2. When people slip or fall on a floor (by self or due to collisions), people get injured and skin gets burnt / damaged.  This is due to friction between the floor/road and the body.

3. Bad friction is when a sharp object  scratches our skin or  sharp objects create scratches on shining tables, shining objects.
