When a ball is dropped it falls due to the force of friction?
No, it falls because of gravity.
What type of friction is involved in walking?
Grip is a type of friction that people need in order to walk comfortably. Without grip, people would slide and have nasty falls.
How does frictional force vary with change in roughness of the surfaces?
More friction is produced on a hard surface than on a smooth surface it takes more force and brute strength to push something heavy on a rough surface, because it falls in the cracks. On a smooth surface you are just sliding across a surface.
What happens to an object when it is thrown in the air?
it is slowed by liquid friction, and pulled to the ground by gravity
Why is friction a nuisance?
it causes falls rsulting in injury and death or disabilities. It destroys valuables or items used every day when dropped. It takes a heavy expensive airplane to flyand causes planes to crash . it causes birds droppings to fall on us. It causes accidents by objects falling on us. It allows bombs to drop on innocent people. It causs leaves to clutter in yards and kill the grass. It causes litter to fall on our roads, neighborhoods and other places causing an eyesore. It allows spills that keep us from eating our food and drinking coffee, coke, etc. It creates damage to rugs, floors, furniture, etc. The baby drops his milk and cries. Gravity is not a nuisance. Our agendas are the nuisances.

Hail falls to the ground because of the force of?
When hail falls to the ground, it is because of the force of FRICTION!! :)
What is undesirable?
An example of undesirable friction is when a cyclists falls and his face against pavement that skin on the road. Undesirable friction is something that is not controllable.
What causes a metamorphic rock to change into an igneous rock?
it falls in magma and melts to molten rock and when it pops out of the volcano and hardens its a igneous rock!
What causes skin tears in elderly people?
The are many causes of skin tears in elderly people. This may include friction, exposure to ultraviolet rays and so much more. The skin for the elderly so fragile.
What force opposes gravity when a leaf falls?
Friction and the molecules slowing down the leaf.
What causes drownings?
falls, swimming, watercraft, bathing
What causes the water to change during the water cycle?
it rains then logicly falls down causing the rain to make a confirmed watercycle wait im just a kid haha!
Which change in a stream causes deposition?
A stream deposition occurs when, in the lower reaches, the flow of water (speed of flow) is reduced. Which is when the heavier sediment falls out and settles on the river bed.
How does Vegatation change climate?
Vegetation changes climate by blocking wind and creating shade. This cools areas of the land and causes warm air to rise while cool air falls.
Why does the hot glass of a kerosene lamp cracks when wet with water?
The glass of a kerosene lamp while glowing is hot. When water falls on it, there is a sudden change in temperature, which causes the glass to break.
Evaporation rises or falls?
Evaporation causes water levels to fall as water turns to steam and evaporates into the air.
