From the first law of thermodynamics, energy is conserved. Energy can exist in two forms: potential or kinetic. A moving object has kinetic energy, and when an object is subject to friction, heat is generated. Some of the kinetic energy of the object is converted into heat. Heat is really just the speed at which the molecules move. So the kinetic energy (energy of its momentum) is converted into the kinetic energy of everything that is warmed by the friction.

What force makes it less likely for a person to slip on a dry sidewalk as opposed to an icy sidewalk?
Friction is the force that makes it less likely for a person to slip on a dry sidewalk compared to an icy sidewalk. Dry surfaces provide more friction between the shoe and the ground, allowing for better grip and stability. Ice reduces this friction, making it easier for a person's foot to slip.
What makes something solid?
Solids have a strong intermolecular force between their particles, which prevents them from moving freely. The particles in a solid are arranged in a fixed, orderly structure, giving the solid a definite shape and volume. This arrangement results in solid objects having strong and rigid properties.
Role of friction in cricket?
To the bowler, friction is a great aid in determining the spin and bounce of the ball. And to a fielder when returning the ball. To the batsman - not much.Similar comments apply to baseball, Netball and basketball etc.
What force is when a ball rolls across the floor?
The force that stopped it is a resistive force. Assuming there are no external force acting on it, Friction is the cause. When the ball is rolled, a force is applied. According to Newton's second law, F=ma, There is an acceleration, thus increase in velocity. At that same instance, when the ball moves, a natural resistive force, friction is produced. However at the next instance, there is no force pushing the ball, since friction exists when there is velocity, there will be a net force against the direction of travel. Thus generating a Deceleration. This happens till the ball comes to a stop, when it do not have any more speed. "Friction exists when there is motion" - this is a derivation from Newtons Third Law of motion. when the ball is moving it applies some force on ground so the ground also applies an equal and opposite force on the rolling ball. But since the vector component of the force on the ball that set it into motion is larger it keeps rolling till the time the Frictional force can bring it to an complete halt.
What is a wind moving in two directions over a prairie makes air in the middle spin called?
A wind moving in two directions over a prairie that makes air in the middle spin is called a vortex or a whirlwind. This phenomenon occurs when different wind speeds or directions create a rotating column of air, often seen in tornadoes or dust devils.
What force makes it hard to start moving objects?
The force that makes it hard to start moving objects is static friction. Static friction is the force that opposes the initiation of motion when two surfaces are in contact but not moving relative to each other. It must be overcome by an external force to set an object in motion.
Why do some objects move continuously while some moving objects stop suddenly?
Because of friction, Friction is what causes moving objects to slow down and eventually stop. This is an important science idea we can use to describe the force that pushes back on a moving object and makes it slow down and stop.
Does friction makes objects move faster over an inclined plane?
No, friction tends to oppose the motion of objects moving over an inclined plane, which can make them move slower rather than faster. The amount of friction between the object and the surface of the inclined plane can affect how quickly the object accelerates or decelerates while moving.
What are the consequences of friction?
Friction requires that forces be greater to move an object, but friction also makes it possible for an object to stop moving without an external applied force. Remember, friction ALWAYS opposes motion.
What makes an object in motion slow moving?
friction
A force between two moving objects that make it hard for them to move?
Frictional force exist between two moving objects that make it hard for them to move.Frictional force causes objects to slow down if force is not applied continuously to the moving objects. Frictional force causes some of the energy to be converted into the wasteful form of energy.
What makes brakes squeak?
The friction between 2 objects makes them squeak
What is The force that makes it difficult to push objects?
The force that makes it difficult to push objects is friction. Friction is the resistance that occurs when two objects rub against each other, and it depends on the roughness of the surfaces and the force holding them together.
How does friction help?
If there was no friction the vehicles would never stop, we couldn't write on the board as friction makes chalk writing visible. Without friction no building could be constructed, the vehicles on the road would never move. Friction helps a lot in many ways and is a necessary in our life.
What makes sliding difficult?
when two objects slide over each other, there is friction between them, the more friction, the harder it is to move one of the objects over the other.
What force a substance that reduces friction and makes objects slide past?
oil
Friction makes what possible?
Friction makes it possible for objects to grip and move against each other. It also allows us to walk, drive, and hold objects firmly in place. Additionally, friction generates heat and can be harnessed in various machinery and tools for controlled motion and braking.
