  1. Forces & motion

    Use net force to calculate acceleration

    Apply Fnet = ma in one dimension using mass in kilograms and net force in newtons.

  2. Electricity

    Relate voltage, current and resistance

    Use V = IR for a stated ideal ohmic component and keep amperes, volts and ohms distinct.

AN EXAMPLE FROM THIS CHAPTER

A 4 kg cart experiences a net force of 12 N to the right. What is its acceleration magnitude?

Show answer & explanation

3 m/s2

a = 12 ÷ 4 = 3 m/s2, directed right.
