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.

Friction opposes motion by creating resistance between two surfaces in contact. This resistance reduces the speed of an object in motion. The law of conservation of energy applies in this scenario as the energy lost due to friction is converted into other forms, such as heat or sound, maintaining the total energy within the system.

How does the law of conservation apply to skatboarder on a half pipe?
The law of conservation of energy applies to a skateboarder on a half pipe by ensuring that the total mechanical energy in the system (potential energy due to height and kinetic energy due to motion) remains constant, neglecting any external forces like friction or air resistance. As the skateboarder moves up and down the half pipe, their potential energy is converted into kinetic energy and vice versa, but the total energy remains the same.
Does the law of conservation apply to death?
No, the law of conservation of energy does not directly apply to death as it pertains to the physical transfer and transformation of energy. However, matter and energy are not created or destroyed in death, but rather transformed, as the body decomposes and returns to the environment in various forms.
Do the laws of motion apply to the speed of light and movement in atoms?
The laws of motion do not apply to the speed of light, as light does not obey classical mechanics but rather follows the principles of special relativity. However, the laws of motion can be used to describe the movement of atoms at macroscopic scales, although quantum mechanics is needed to fully understand the behavior of particles at the atomic level.
What if your walking down the street describe the forces acting on you and use Newton's laws of motion to describe your motion?
When walking down the street, the two main forces acting on you are gravity pulling you down towards the Earth and the normal force from the ground pushing you up. According to Newton's first law of motion, if the forces are balanced (in this case, gravity and the normal force), you will continue moving at a constant velocity in a straight line. If you want to change your motion (speed up, slow down, change direction), you would need to apply an additional force in the direction you want to move.
What should you do when your knuckle swells up?
If your knuckle is swollen, you can apply ice to reduce swelling, elevate your hand above your heart to reduce inflammation, and rest the affected hand to allow for healing. If the swelling persists or is accompanied by severe pain or loss of motion, it's best to consult a healthcare provider for further evaluation and treatment.
Does force and motion apply in space?
Yes, force and motion still apply in space. Objects in space are affected by forces such as gravity, friction, and momentum, and will continue to move or change direction based on these forces. However, since space is a vacuum, there is very little resistance to motion, so objects can continue moving at a constant velocity unless acted upon by another force.
What force stops the motion of a bike?
Friction between the tires and the ground is the force that slows down and stops the motion of a bike. This friction comes from the contact between the rubber of the tires and the surface of the road. Additionally, the brakes on the bike can be used to apply a force that helps stop the bike's motion.
Which is more accurate to find velocity conservation laws or projectile motion?
Both velocity conservation laws and projectile motion are fundamental concepts in physics. Velocity conservation laws are more general principles that apply to any system where no external forces are involved, while projectile motion specifically deals with the motion of objects under the influence of gravity. In terms of accuracy, both concepts are equally important in their respective applications.
What careers deal with force motion and friction?
Some careers that deal with force, motion, and friction include mechanical engineers, physicists, and automotive engineers. These professionals work to understand and apply these concepts in various industries such as manufacturing, research and development, and transportation.
What is impending motion?
I'm pretty sure it means the motion or movement that is going to happen. So, if you apply force in a direction to a box, the impending motion will be sliding or tipping in the direction of force depending on certain coefficients of friction.
1 In a collision that is inelastic the total what after the collision is not the same as before the collision?
Hi, in line with Newton's laws of motion the momentum before and after a collision is always conserved (when no external force is applied to change the systems momentum). In elastic collisions we can apply the conservation of momentum and conservation of energy principles. In inelastic collisions we can only apply the conservation of momentum principle. Energy is not conserved in inelastic collisions because energy is lost through small deformations, noise, friction, etc. We can compute the coefficient of restitution that helps determine this degree of energy loss from impulse-momentum equations.

When a car stops the brakes heat up because of friction what is this an example of?
This is an example of kinetic friction, which is the force that opposes the motion of two surfaces sliding against each other. When you apply the brakes in a car, the brake pads exert a force on the rotating wheels, resulting in friction that slows down the car and generates heat due to the surfaces rubbing against each other.
What is abbreviation for apply to affected area?
Apply to affected area will be AAA (Apply to Affected Area every 12 hours = AAA q12h)

What are the principles of friction?
Friction is caused by the interaction of two surfaces in contact. The frictional force opposes the motion of an object or resists the force applied on it. Frictional force is dependent on the nature of the surfaces and the normal force pressing them together.
Does the Law of Conservation of Mass apply to dissolving?
NO
