Why Isn't the Normal Force on the Sled 250 N?

In summary, a friction sled slope is a device used to measure the force of friction between two surfaces by using a ramp or slope with a sled or block that is pulled down by a string or pulley system. It works by using the force of gravity and can be affected by factors such as the angle of the slope, weight of the sled, and type of surface. The coefficient of friction, which is calculated by dividing the force of friction by the normal force, can be determined through this experiment. Friction sled slope experiments have real-world applications in fields such as automotive design and engineering research.

Homework Statement


The question is: An empty sled of mass 25 kg slides down a hill with constant speed of 2.4 m/s. The slope of the hill is inclined at an angle of 15 degrees

How come the normal force of the sled is NOT 250 N?

Assuming here g= 10 N/kg, the weight is 250N.

However since the mass is moving down an incline at 15 degrees, the normal force will be a component of the weight i.e. a fraction of the weight.

1. What is a friction sled slope?

A friction sled slope is a device used in physics experiments to measure the force of friction between two surfaces. It consists of a ramp or slope with a sled or block that is pulled down by a string or pulley system. By measuring the angle of the slope and the force needed to move the sled, the coefficient of friction can be calculated.

2. How does a friction sled slope work?

A friction sled slope works by using the force of gravity to pull a sled or block down a ramp or slope. As the sled moves, the force of friction between the sled and the surface of the slope slows down its movement. By measuring the angle of the slope and the force needed to move the sled, the coefficient of friction can be calculated.

3. What factors affect the results of a friction sled slope experiment?

There are several factors that can affect the results of a friction sled slope experiment. These include the angle of the slope, the weight of the sled or block, the type of surface used for the slope, and any external forces acting on the sled such as air resistance or uneven surfaces.

4. What is the coefficient of friction and how is it calculated?

The coefficient of friction is a measure of the amount of resistance between two surfaces in contact. It is calculated by dividing the force of friction by the normal force, which is the force exerted by the surface on the object. In a friction sled slope experiment, the coefficient of friction can be calculated by dividing the force needed to move the sled by the weight of the sled.

5. What are some real-world applications of friction sled slope experiments?

Friction sled slope experiments have many real-world applications, such as determining the best materials for car tires, designing efficient braking systems for vehicles, and understanding how different surfaces affect the movement of objects. They are also commonly used in engineering and physics research to study the properties of friction and develop new technologies.
