Which Force Is Called Opposing Force?

Which Force Is Called Opposing Force? Why friction is called opposing force? Friction is the force created due to relative movement between two surfaces. Friction is an opposing force that opposes the motion of one body over the surface of another body. What is Opposing force in air? The air resistance is a special type

What Is Coefficient Friction?

What Is Coefficient Friction? Coefficient of friction (COF) is a dimensionless number that is defined as the ratio between friction force and normal force (Eqn (2.1)). Materials with COF smaller than 0.1 are considered lubricous materials. COF depends on the nature of the materials and surface roughness. How do you find the coefficient of friction?

How Do You Find The Average Resistive Force?

How Do You Find The Average Resistive Force? The average resistance force is the change in momentum divided by the time required to stop the bullet. The distance covered under constant acceleration is 1/2 a* t^2. The average acceleration is the change in velocity divided by the time. How do you find the resistive force
