please try to get it right
and I need answer very easy answer / very easy words.
and you have to solve last three sums
Answers
Answer:
1. due to friction
2. gravitational force pulls it down
3. they get spoilt if used more
4. there is more friction on smooth surface
5. gravitauional force
Answer:
1.
When you rub your hands together, the action of scraping the surface of your skin back and forth against each other causes the molecules in your skin to move a little faster. The faster that molecules move, the higher the temperature. So the friction of rubbing your hands together makes them feel warmer.
2.
when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.
4.it is because there is friction present between your shoes and the ground. ... Smooth surfaces : Smooth surfaces has very less friction, very less interloction, very less ridges and grooves, so we will not have grip on the surface and we slide, and makes it difficult to walk on smooth surfaces.
