Newtons laws of force

Question 1

What is the formula of gravitational force between two objects?

Answer 1

F = (G * m1 * m2)/r^2

Question 2

How is kinetic frictional force calculated?

Answer 2

Fk = uk * N

Question 3

How is static frictional force calculated?

Answer 3

Fs </= us *N

Question 4

calculate force.

Answer 4

F = mass * acceleration 
Newtons = kg * m/s^2

Question 5

Centripetal acceleration

Answer 5

a = V^2/r

Question 6

What is weight

Answer 6

a force

W= mg
