Answer:
Friction
Explanation:
Friction is a force that slows down moving objects. If you roll a ball across a shaggy rug, you can see that there are lumps and bumps in the rug that make the ball slow down. The rubbing, or friction, between the ball and the rug is what makes the ball stop rolling. External Force is required.
This is true, I believe.

Answer:
Elements are made up of only one type of atom. Each element has a unique chemical symbol. Elements can be identified by their atomic number.
The reason why the reaction takes place faster when the
temperature is higher is that the collision of particles of the object
increases. In order to have a faster reaction, you would need the particles of
the object to get excited and increase its collision to other particles. This
can be achieved through increasing the temperature.
