Because a round object has less surface area in contact with the solid surface it's being propelled upon, there is less friction between the two objects and the sphere will travel farther on that surface than a flat object (lots of contact....lots of friction....and therefore, resistance to motion) due to the difference in friction.
What else can I help you with?
What does the force acting between any two surfaces moving past one another mean?
the force acting between any 2 surfaces moving past one another is friction. and friction is just where they grip to each other cause the little bumps and groves in the surface of the objects hit each other and are forced to move over, around, or destroy the other.
Do balloons create friction?
Balloons do not create friction on their own. However, when a balloon rubs against another surface, like when it is rubbed against clothing to create static electricity, friction can be generated. This static electricity can cause the balloon to stick to certain materials due to the attraction between positive and negative charges.
What are the static and kinetic coefficients of friction between flint and high carbon steel?
The static coefficient of friction between flint and high carbon steel is typically around 0.6 to 0.8. The kinetic coefficient of friction between the two materials is slightly lower, usually around 0.5 to 0.6. Keep in mind that these values can vary depending on factors such as surface roughness and contact pressure.
How does changing the shape of an object affect the friction and air resistance?
Changing the shape of an object can affect friction and air resistance. For friction, the surface area in contact with another surface can increase or decrease, altering the friction force. For air resistance, a more streamlined shape will experience less resistance compared to a less streamlined shape due to differences in how air flows around the object.
What is the coefficient of friction of linoleum rubber?
The coefficient of friction of linoleum rubber can vary depending on factors such as surface texture, temperature, and the presence of contaminants. In general, the coefficient of friction for linoleum rubber is typically around 0.8 to 1.0. It is always recommended to test the specific linoleum rubber surface in question to determine its exact coefficient of friction.
Does friction exist on a stationary object on a flat surface?
Yes, friction still exists on a stationary object on a flat surface because there are microscopic irregularities on both the object and the surface. These irregularities cause interlocking between the two surfaces, resulting in static friction that opposes any tendency for the object to move.
Coefficient of friction for glass on wood?
The coefficient of friction between glass and wood can vary depending on factors such as surface finish and moisture content. However, on average, the coefficient of friction for glass on wood is around 0.4 to 0.6. This value indicates moderate to high friction between the two surfaces.
What is the coefficient of friction between aluminum and steel?
The coefficient of friction between aluminum and steel is typically around 0.61 to 1.0.
How can you decrase friction?
Depends what you want to increase/decrease friction on. If is like a weight on the floor.. Then to increase the friction all you have to do is increase the weight, To reduce it you either reduce the weight or get a smoother surface, or maybe a cloth in-between the floor and the weight.
What is the average coefficient of friction for a dry road?
The average coefficient of friction for a dry road is typically around 0.7-0.8. This means that the frictional force between tires and the road surface is 70-80% of the normal force pressing the tires onto the road.
What effects does friction have between a wooden block and the surface its resting on?
Oh, dude, friction between a wooden block and a surface can cause the block to stay in place instead of sliding around like a drunk penguin on ice. It's like that annoying friend who always puts the brakes on your plans to have a smooth ride. So yeah, friction basically stops things from moving when they're not supposed to.
What is the coefficient of static friction between a wooden bench and a cardboard box?
The coefficient of static friction between a wooden bench and a cardboard box may vary depending on the specific materials and surface conditions, but it is typically around 0.4 to 0.6. This means that it would require a force equal to 40-60% of the normal force between the two surfaces to overcome static friction and start the box moving on the bench.
