# Question: Newton s second law of motion Section 4 3 is expressed by

Newton’s second law of motion (Section 4.3) is expressed by the equation F = ma, where F represents force, m is mass, and a is acceleration.

(a) The SI unit of force is, appropriately, called the newton (N). What are the units of the newton in terms of base quantities?

(b) An equation for force associated with uniform circular motion (Section 7.3) is, F = mv2/rwhere v is speed and r is the radius of the circular path. Does this equation give the same units for the newton?
