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.
Friction can slow down the movement of objects, but it does not always stop them completely. The amount of friction depends on the surfaces in contact and the force pushing them together. If the force is strong enough to overcome friction, the object may continue moving.
No, if you are going down hill on your bike then friction makes your bike go, but some time it is going to stop.
force = mass x acceleration. Frictional force is opposed to the direction of motion so the object decelerates, unless other forces (gravity etc) play any role.
It is true that friction brings most moving objects to a stop. An example of this would be a car being stopped by brakes.

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?
Friction in cricket plays a crucial role in allowing the ball to grip the pitch and deviate from its intended path when bowled. This helps bowlers generate swing or spin, making it harder for the batsman to predict the trajectory of the ball. Additionally, friction between the bat and ball determines the amount of power and direction with which the ball is hit by the batsman.
What force is when a ball rolls across the floor?
The force that causes a ball to roll across the floor is primarily due to friction between the ball and the floor. As the ball's surface interacts with the floor, friction pushes against the direction of motion, allowing the ball to roll. Other factors like gravity and air resistance may also contribute to the ball's motion.
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?
Objects can continue moving continuously due to inertia, which is the tendency of an object to keep moving in a straight line unless acted upon by an external force. Objects can stop suddenly if a force, such as friction or air resistance, acts upon them to counteract their motion and bring them to a halt.
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?
The force that makes it hard for two moving objects to move is called friction. Friction occurs when two surfaces are in contact and oppose the motion of each other. It depends on the nature of the surfaces in contact and the force pressing them together.
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?
Friction helps by providing grip and traction between objects in contact, such as between a car's tires and the road. This allows us to walk, drive, and manipulate objects. Friction also helps in slowing down moving objects, like brakes on a bicycle or a car.
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
Name 3 effects that can be caused by friction?
1.If you rub your hands that is an effect caused by friction. 2. Heat and rubbing from friction can cause wear and tears on rubbed places. 3.Rough surfaces such as where snow is melted causes dirt to poke through the holes which gives enough friction to stop the sled.
