How do you calculate friction force with mass and acceleration?

What is the frictional force equal to?

The frictional force is equal to the frictional coefficient times the normal force. Friction is caused due to attractive forces between the molecules near the surfaces of the objects.

How do you find friction force without coefficient?

How do you find force with mass and friction?

Calculating the Force of Friction
  1. N = m g N= mg N=mg.
  2. N = m g cos ⁡ θ N=mg\cos{\theta} N=mgcosθ
  3. F = μ N F=\mu N F=μN.

How do you find net force with friction?

When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = Fa + Fg + Ff + FN.
