Friction opposes motion so the friction force will be in the direction opposite to that in which the fridge is pushed.
The friction force between the refrigerator and the floor depends on the coefficient of friction between the two surfaces and the force applied to push the fridge. The friction force will act opposite to the direction of motion to prevent the fridge from sliding. It is essential to overcome this friction force to move the refrigerator.
If the question has to do with the environmental process of soil liquefaction, the water between the grains stays were it is, which causes the soil grains to lose friction and therefore makes it act as a liquid.
In fact, there is an infinite number of answers because force is a vector, meaning that it has a magnitude and an orientation. For example, if someone pushes horizontaly onto the book (10N) and the friction is 8N in the opposite direction, the resultant force is 2N. But if the book is pushed at an angle, the resultant force changes.
Yes, wood can be used to create static friction when two wooden surfaces rub against each other. Static friction occurs when an object at rest is being pushed or pulled, causing a resistance force between the surfaces in contact. The rough texture of wood can increase the frictional force and prevent the object from moving easily.
It can be either. Horse-drawn carts are virtually all pulled. Library and shopping carts are pushed. However, any pulling or pushing force that is exerted includes a pushing force against the ground (i.e. friction).
The action force in a rocket balloon lab is the air being pushed out of the balloon in one direction, propelling the balloon in the opposite direction as a reaction force. This action-reaction pair follows Newton's third law of motion.
If they are touching yes and the harder they are being pushed together the greater the friction.
kinetic friction
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.
When you plug in your fridge, the electricity energises the freon in the copper piping, which then spreads all over the fridge cooling it down. The biggest pipes are at the top, which pushes cold air to the bottom. Doing so, the warm air is in turn pushed up and when it gets to the top, it is cooled by the pipes. The process is then repeated over and over and over. This is how the food is cooled in a fridge xxx
The static friction between the wheels of the wagon and the surface it's resting on prevents it from rolling until a force is applied to overcome this friction and set the wagon in motion.
Escherichia coli , salmonella, Staphylococcus
Friction between two solid objects is caused by the roughness of their surfaces creating interlocking and resistance to motion. When the two objects are pushed or pulled against each other, the microscopic asperities on their surfaces catch on each other, leading to the force of friction opposing the motion.
friction
yes and no, It depends on what type of friction. it has no friction with the table, but it does have friction from the air being pushed from beneath. What slows the puck down the most is air resistance
When a pendulum swings and is not continually pushed, the energy is gradually lost to friction and air resistance, causing the pendulum to slow down and eventually stop. This lost energy is converted into heat due to the friction between the pendulum and the air or any other surfaces it comes in contact with.
