The role of friction is of great importance when creating safety ramps and escalators because with the help of friction things move.
<h3>Why is it important to move objects slowly on ramps and escalator?</h3>
It is important to move objects slowly on ramps and escalator because the ramps and escalator moves object in the opposite direction of gravity. If we did not move objects slowly, then the objects or a person get damaged.
So we can conclude that the role of friction is of great importance when creating safety ramps and escalators because with the help of friction things move.

Indicate valleys, hills, steepness and gentleness of slopes.
When the two forces of gravity and air resistance become the same, the object no longer speeds up, and it doesn't slow down either. This is called terminal velocity
So the answer is b
Answer: The answer is 3 either physical or chemical properties
Explanation:
because all properties of matter are either physical or chemical
