The force of friction is directed opposite of the way an object is moving because?
The force of friction is NOT ALWAYS directed opposite the direction an object is moving. Consider, for example, an object (like a book) resting on a piece of paper on a table. If you gently pull the paper and the book moves with the paper, friction between the paper and the book is causing the book to move in the same direction as the paper. Even if you pull a bit faster and the book slides in the same direction as the paper motion, but a little bit slower, the friction is the force which is pulling the book along--in the same direction of the paper motion.The direction friction is acting is opposite the direction of the relative SLIDING or attempted sliding of surfaces. In the cases above, without friction, the book would slide opposite the direction of paper motion, so the friction is in the same direction, accelerating the book along with the paper. In the first case, the book's acceleration is the same as the paper's; in the second, the book's acceleration is less than the paper's causing the book to actually slide backwards relative to the paper's motion.
When a machine drills holes in metal some of the work input is used to overcome what?
Friction :) it says so in in my science book.
Give the example of activities at home where friction is useful?
walking, stirring things, sitting down, standing up, reading a book, opening the door. eating, cooking, dressing. ooooh. there is a real funny one too but i don't think i can say it here. hint hint.
What is an example of a sentence?
I am writing a book. There are no cats here. My voice is amazing.
Think Critically A book sliding across a table slows down and comes to a stop Explain whether the forces acting acting on the book are balanced or unbalanced.?
The forces are unbalanced. The force of Friction is obviously greater than whatever force is pushing the book in the direction of travel, if one is pushing it at all. If the forces on the book were balanced, the book would continue to slide with a constant velocity.
What is one example of sliding friction?
Pushing a book across a table creates sliding friction between the book and the table surface, which acts in the opposite direction of the pushing force, making it harder to move the book.
Explain the difference between static friction and kinetic friction. Give an example of each.?
Static friction occurs when two surfaces are not moving relative to each other, while kinetic friction occurs when two surfaces are sliding past each other. An example of static friction is trying to push a heavy box that won't budge, while an example of kinetic friction is the resistance when sliding a book across a table.
What is the difference between asking and telling?
Telling is act of saying about something what one already know. Asking is the act of inquiring about something one has/needs to know. An example of telling is "Your book is lying there". An example of asking is "Did you see my book".
When you push a book why does it stop?
When you push a book, it stops because of the force you are applying to it. The friction between the book and the surface it is resting on counteracts the force you are applying, bringing the book to a stop.
What type of friction holds a penny on surface of book when lift cover?
static friction, friction between two non-moving objects.
What is the difference between has and have and give an example?
the difference between has and have is that you use has in sentences with : ( she , he and it ) for example : she has a book . but you use have in sentences with : ( I , you , we and they ) for example : you have a book , I have a book .
Examples of static kinetic and rolling friction?
friction between a sticky note and the page of a book as it marks your place
An example of kenetic fritcion?
Kinetic friction is when two objects are rubbing against each other. Putting a book flat on a desk and moving it around is an example of kinetic friction.
Which force slows a book sliding on a table?
The force that slows down a book sliding on a table is mainly friction. As the book moves across the table, the friction between the book and the table surface opposes the motion, causing the book to slow down until it eventually stops.
What a example of unbalanced force that caused a change in motion?
An example of unbalanced force causing a change in motion is when a person pushes a book across a table. The force exerted by the person is greater than the force of friction between the book and the table, causing the book to accelerate in the direction of the push.
What are the effect of friction on a body give at least 2 examples?
Friction reduces the speed of a moving body by opposing its motion. For example, friction between the tires of a car and the road slows down the car's acceleration. Friction between a book sliding on a table surface slows down its movement.
What type of friction would be used to cause a book to slow down and stop when pushed?
The type of friction that would cause a book to slow down and stop when pushed is kinetic friction. As the book moves across a surface, the frictional force between the book and the surface opposes the motion, eventually stopping the book altogether.
