# Friction force and mass

Q: the coefficient of static friction between a book and the level surface it slides on is 065 if the mass of the book is 20 kg, what minimum initial applied force is required to slide the books across the surface. The force of friction box 1, a wooden box, has a mass of 860 kg and a coefficient of kinetic friction with the inclined plane of 035 box 2, a cardboard box . What is a force learn about newton's laws of motion and the force of friction revise calculating unbalanced forces, weight and mass with bbc bitesize. The friction force is still pushing back and this is what makes it so difficult to continue to slide the object where f is the force, m is the mass and a is the .

The force of friction can be simply calculated depending on the mass of the object, the materials you're considering and whether the object is already moving or starting from stationary. Weight affects friction in that friction is directly proportional to the weight of the load one is moving if one doubles the load being moved, friction increases by a factor of two friction is the force that opposes motion of one object over another friction is sometimes beneficial as when . By steven holzner you can use physics to calculate the kinetic energy of an object when you start pushing or pulling a stationary object with a constant force, it starts to move if the force you exert is greater than the net forces resisting the movement, such as friction and gravity.

Kinetic friction formula questions: 1) a worker in a stock room pushes a large cardboard box across the floor the coefficient of kinetic friction is μ k = 0520 the box has a mass of 750 kg, and the worker is exerting a force of 4000 nforward. The acceleration of the object is directly proportional to the force and inversely proportional to the mass of the object in simple terms, it makes an object to move from its rest position force is a vector quantity as it has both magnitude and direction. When the object is actually moving, the friction is said to be kinetic friction which is generally less than static friction if we add more mass we increase the normal force (n) (because the weight has increased) and hence we have increased the total frictional force. The force of static friction f s f_s f s (1 1 0 kg) (9 8 m s 2) (plug in the coefficient of static friction, mass, and value of g) f_{s\text what is friction .

If the fully-loaded sled has a mass of 700 kg, what is the maximum force of static friction, and is the force applied enough to overcome it answer: on a flat surface, the normal force on an object is η = mg . Calculating the values of friction forces acting between the surfaces of two bodies in contact with each other, using friction formula and equation, and applying the concept of static friction. The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it there are at least two types of friction force - sliding and static friction though it is not always the case, the friction force often opposes the motion of an object. While sliding, the only force acting on the block in the horizontal direction is that of friction from the mass of the block and its acceleration, you can find the frictional force and finally, the coefficient of kinetic friction okay, so we are sliding a steel block with various added weights on . This force is the static friction force the fact that it acts opposite to the direction in which the other forces would, collectively, accelerate the object explains the statement of property 1 we can carry this example a bit further to illustrate property 2.

Objects that have more mass allows gravity to pull harder on them an example of this might be an iron cube versus a wooden cube an iron cube has more mass than a wooden cube and is more difficult to move when you put friction on it than the cube of wood. Q: an engine provides 50 kn of force to keep a 1600-kg vehicle moving at a uniform speed (air resistance is negligible) what is the coefficient of rolling friction between the tires and the road surface. The force of friction is equal to the coefficient of friction times the normal force since normal force is equal to mass times the acceleration of gravity (98 m/s2), the force of friction is .

## Friction force and mass

Friction does not depend on the mass of the body it depends on the normal force and the roughness of the surface in contact when a body is placed on the ground, the mass of the body (weight= massacceleration due to gravity) comes into play for. I'm aware that this is extremely basic but i've forgotten how to get the coefficient of friction when given a forward force and acceleration can someone describe to me the algorithm for solving the. 1 the problem statement, all variables and given/known data if a force of 45 newtons is needed to overcome friction and the coefficient of friction=026, what is the mass of the object. The product of mass times gravitational acceleration, mg, is known as weight, which is just another kind of forcewithout gravity, a massive body has no weight, and without a massive body, gravity .

If an applied force f= n is opposed by friction with friction coefficient mu = acting on mass m= kg then the the frictional resistance force is n and the net force is = n newton's second law becomes:. A bike and rider with a combined mass of 700 kg ride down a hill with an acceleration of 225 m/s2 what is what is the net force acting on the bike and rider.

The friction force is the product of the friction coefficient and the normal force, which in the absence of extra downward forces, is the weight of the object weight (w) is defined as the mass (m) of an object times the force of gravity (g): f n = w = mg. Friction force has nothing to do with mass of the objectsuppose there is a metallic box on a table and when you move the box it experiences some frictional force if you put another box on the same box and try to move, then system experience more frictional force (considering all the conditions ,except for there are two boxes in second case . Your brother’s car has a mass of okay, so the force applied to accelerate the car steadily is 5,060 newtons now all you need is the average speed.
