Friction equals the coefficient of friction times the normal force.
Friction increases as the roughness of the materials increases. It also increases as the force pushing the materials together increases.
Mass And Velocity
How rough it is and how heavy it is.
Work is done when an object moves in the direction in which a force is applied to it. So the factors are the magnitude and direction of the applied force and the factors which affect the object's motion. The latter will include the mass of the object and friction (including drag).
Cohesive or Adhesive force between the two objects.
Thrust and friction in the environment. Ignoring friction, the two chief factors are the force of acceleration and mass, which determines how much force is required to achieve a given speed (more technically the change of velocity: speed in a given direction).
Inertia
The coeffient of friction. The force holding the 2 surfaces together.
mass and velocity
Mass and velocity.
Mass And Velocity
How rough it is and how heavy it is.
The frictional force is described by F = μR where μ is the coefficient of friction (the roughness of the surface) and R is the force the object exerts perpendicular to the surface.
