In order to move an object at rest you must make sure the forces acting on that object are what?
To move an object at rest, you must apply a force to overcome the force of static friction that is keeping the object stationary. Ensuring that the applied force is greater than the force of static friction will allow the object to start moving.
How is motion affected by friction and how does the law of conservation apply to this?
Friction is a general term applied to the force on something that is applied to it by something that it is moving on or through. If a car is moving along the highway, there is friction between the road and the tires. There is also friction in the wheel bearings. (Lubrication helps limit this.) The friction, the forces between the two things that are moving, appears as heat energy. And by the law of conservation of energy, if something is moving across something else, there will be a bit of energy lost due to friction, but it will have to be conserved - it will have to appear somewhere else because it can't just "disappear" without being accounted for. Friction energy is conserved (law of conservation of energy) and heat results. If someone is doing a project that involves using an abrasive on a material, someone might be sanding wood or metal (or another material). The sandpaper and the material being sanded will get warm as sanding continues. The friction created between the abrasive and the material appears as heat. The energy is conserved; it cannot be lost nor can it simply disappear. Links follow.
If your pulling 30 lb tire on a lawn what is the estimated weight youre actually pulling because of friction?
the equation for static friction coefficient is:static friction coefficient = force required to break bond / weight of object (tire)you need the friction coefficient between rubber and grass, say its 0.5, this means the force you have to apply to equal the friction force is:0.5 = x / 30x = 0.5 * 30x = 15 lbs fanything greater than 15 lbs f will break the bond and accelerate the tire.notes :1 / moving friction coefficient is usually less than static friction coefficient, so youve less drag once its moving.2 / friction coefficients are never greater than 1.0actually , some friction coefficients do exceed 1.0 , see google / friction coefficients table
What is the force used to turn off a water tap?
The force used to turn off a water tap is typically a combination of torque and friction. When you rotate the handle or lever, you apply torque, which is the rotational force that allows the valve mechanism to close and stop the flow of water. The friction between the moving parts of the tap also plays a role in ensuring that the valve seals properly to prevent leaks.
When the mover pushes the boxtwo equal forces result.explain why the box moves even though the forces are equal and opposite.?
When the mover pushes the box, they apply a force in one direction, while the box experiences an equal and opposite force from friction or resistance. If the applied force exceeds the static friction threshold, the box overcomes this resistance, resulting in movement. Thus, even though the forces are equal and opposite, the box moves due to the unbalanced forces acting on it when the applied force is strong enough to surpass friction.
When you apply the brakes what kind of friction is that?
When you apply the brakes, you are experiencing kinetic friction between the brake pads and the brake rotors. This friction converts the kinetic energy of the moving vehicle into thermal energy, which helps slow down the vehicle.
How do you apply friction?
Friction acts in the opposite direction that the object is moving or trying to move. The force of friction is calculated by multiplying the normal force of the object, usually mass times gravity, by the coefficient of friction.
What is an example of being opposed by static friction?
When you move a heavy object, you must apply a lot of force before the heavy object begins to move. This resistance you feel while the box is NOT moving is static friction. Static friction opposes movement in an initially non-moving object.
If we apply oil on door hinges the friction will?
If we apply oil on door hinges, the friction will decrease because the oil acts as a lubricant, reducing resistance between the moving parts. This will make it easier to open and close the door smoothly.
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
What kind of friction opposes your push when you are unable to move a heavy piece of furniture across the floor?
The friction that opposes your push is static friction. This type of friction occurs when two objects are in contact but not moving relative to each other. As you apply force to try to move the furniture, the static friction force prevents the furniture from sliding.
Does friction bring most moving things to a stop?
True though, Any two objects touching posses friction and friction can result in different factors, like sounds, heat or a resistance. if you rub your hands together, friction here results as heat. Moving parts in a machine or something can producing some kinda sound. When you are drive in your car, friction not only helps you to stick to road, not roll over and acts an a opposing force which will in matter of time stop the car if you don't apply additional force.
Why a horse has to apply more force to start a Tonga than to keep is moving?
Because of friction. Every object has 2 friction coefficient values (called Mu and with its own symbol) - one stationary, and the other while the object is moving. It always takes more force (N) to move an object from a stand-still then it does to keep the same object moving.
What could be done to reduce the effect of friction?
To reduce the effect of friction, you can use lubricants such as oil or grease to create a slippery layer between the surfaces. You can also use smoother surfaces or materials with lower coefficients of friction, or apply anti-friction coatings. Additionally, keeping surfaces clean and maintaining proper alignment of moving parts can help reduce friction.
Why will you need to apply grease when the hinges on the door creaks?
Because the 'creak' is the result of friction generated by the hinge parts moving. Grease or oil deposits a thin film of lubricant between the surfaces, preventing friction (and thus the creak) happening.
How can a door hinge be reduced of friction?
One way to reduce friction in a door hinge is to apply lubricant, such as oil or silicone spray, to the moving parts. Regularly cleaning and removing dirt or debris from the hinge can also help reduce friction. Additionally, adjusting the hinge to ensure it is properly aligned and tightened can help prevent unnecessary friction.
How can you makes a moving object stop?
To make a moving object stop, you can apply a force in the opposite direction of its motion, such as braking in a car or pressing on the brakes of a bicycle. Friction between the object and the surface it is moving on can also help slow it down until it eventually comes to a stop.
