Static frictional force is the

• the energy possessed by a moving object

• The force required to cause a stationery object into start sliding on a surface

• The force required to keep an object sliding along a surface

• push or pull on an object

Sliding (kinematic) frictional force is the

• the energy possessed by a moving object

• The force required to cause a stationery object into start sliding on a surface

• The force required to keep an object sliding along a surface

• push or pull on an object

The correct formula for calculating static frictional force is:

• $=\mu_sN$

• $=\mu_kN$

• $=\frac{1}{2}mv^2$

• $=F\times s$

• $=W\div t$

The correct formula for calculating kinematic frictional force is:

• $=\mu_sN$

• $=\mu_kN$

• $=\frac{1}{2}mv^2$

• $=F\times s$

• $=W\div t$

The correct formula for calculating the work done is:

• $=\mu_sN$

• $=\mu_kN$

• $=\frac{1}{2}mv^2$

• $=F\times s$

• $=W\div t$

The correct formula for calculating the power is done is:

• $=\mu_sN$

• $=\mu_kN$

• $=\frac{1}{2}mv^2$

• $=F\times s$

• $=W\div t$

The correct formula for calculating the instantaneous power is done is:

•  $=F\times v$  
  

• $=\mu_kN$

• $=\frac{1}{2}mv^2$

• $=F\times s$

• $=W\div t$
