The equation used to calculate the weight of an object on a plant is F = ma. "F" is the force measures in Newtons, "m" is the mass measures in grams and "a" is the acceleration that accur due to gravity.
I think its ethylene, tell me if i'm wrong
because of the reflection. if this isnt correct pls let me know :)
Answer:
Friction occurs because no surface is perfectly smooth.
Explanation:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
