Which 2 factors influence the size of a frictional force?

The size of the frictional force is influenced by the types of materials in contact and the force pressing the materials together. Smoother surfaces and greater forces typically result in larger frictional forces.


What 3 forces slow a bike down?

1. air resistance 2. frictional force 3.


2 kinds of forces?

Gravitational force, which is the force of attraction between two masses, and electromagnetic force, which is the force between electrically charged particles.


What are the conditions for an object to stay at restto keep moving at constant velocityor to move with increasing velocity?

You have three separate situations here:1. Object stays at rest. The force on the object is not great enough to overcome its frictional forces, or its inertia.2. Object keeps moving at constant velocity. The object's inertia and frictional forces are exactly balancedby the Force exerted on it.3. Object moves with increasing velocity (acceleration). The Force on the object exceeds that necessary to overcome its inertia and its frictional forces.


How do you change the frictional force between two solid surfaces?

You can change the frictional force between two solid surfaces by altering the roughness of the surfaces, increasing the normal force pressing the surfaces together, or using lubricants to reduce friction. Additionally, changing the sliding speed and contact area between the surfaces can also affect the frictional force.


What are three contact forces?

contact forces are those types of forces that result when the two interacting objects are perceived to be physically contacting each other Examples are 1. Frictional force 2. Tension force 3. Normal force 4. Air Drag etc.,


What are the different kind of force?

The different kinds of forces are as follows: 1. muscular force. 2. gravitational force. 3. frictional force. 4. electrostatic force. 5. electromagnetic force.


What is the force that holds 2 or more things together?

What are the 2 factors that affect the frictional force between 2 surfaces?

velocity and texture


An atom has 10 protons in its nucleus and 10 electrons in orbit around the nucleus Frictional forces temporarily srtip away two of the electrons The net charge on this atom is?

+10 + (-8) = +2+10 + (-8) = +2+10 + (-8) = +2+10 + (-8) = +2


What are the 2 factors on which magnitude of frictional force depends?

The magnitude of frictional force depends on the nature of the surfaces in contact and the normal force pressing the surfaces together.
