How friction is useful in pushing a car?
If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.
What friction keeps a wagon from rolling until it is pushed?
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.
What is the word for a force that opposes the motion of an object?
The opposing forces such as friction in case of solids and viscous force in case of fluids are always present in the natural world.a force can cause a resting object to move, or it can accelerate a moving object by changing the object's speed or direction.in a shorter way to say is frictionFriction
What happens to friction if the weight of an object is increased?
If the weight of an object is increased, the friction between the object and the surface it's resting on also increases. This is because the force pressing the object against the surface is greater, resulting in more resistance to motion.
What kind of friction is the one that must be overcomed in order to start something moving?
The type of friction that must be overcome to start something moving is static friction. This friction exists between the surfaces of the object that is stationary and another object it is resting on. Once the force applied overcomes static friction, the object will begin to move.
Is a crate resting on a loading ramp an example of static friction or fluid friction?

Person mass 95kg on a 22kg ladder against frictionless wall angle 65 horizontal 10 m long ladder at rests on wet floor with a static friction 40 what max length person can climb before lader slips?
To determine the maximum length a 95 kg person can climb up a 10 m ladder resting against a frictionless wall, we need to consider the forces acting on the ladder. The static friction force at the base of the ladder must be sufficient to counteract the moment created by the person's weight. Given the static friction coefficient of 0.40 with a total weight of the ladder and person, we can calculate the critical point where the ladder begins to slip. The maximum distance the person can climb before the ladder slips is approximately 4.19 m from the base, taking into account the ladder's angle and the distribution of forces.
What is kinetic friction and static friction?
Friction is the resistance to movement of an object pressing/resting/moving on a surface. It's not intuitively obvious but the standing still friction and moving friction are different. Assume you have a block of wood resting on a tabletop. The amount of force required to make the block begin to move (static friction) is greater than the force required to keep it moving (kinetic friction) after it has begun to move.

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 kind of friction is the one that must be overcomed in order to start something moving?
The type of friction that must be overcome to start something moving is static friction. This friction exists between the surfaces of the object that is stationary and another object it is resting on. Once the force applied overcomes static friction, the object will begin to move.
What factors determine the of friction between a wooden block and the surface it is resting on?
The factors that determine the friction between a wooden block and the surface it's resting on include the roughness of the surfaces in contact, the weight of the block, and the materials involved. Friction is also influenced by the normal force acting on the block, which is the force exerted by the surface perpendicular to the contact area.
What is the total mass of the system when a 12 kg box resting on a horizontal frictionless surface is attached to a 5 kg weight?
When a 12 kg box is attached to a 5 kg weight, the total mass of the system is 17 kg.
