An 8-newton net force acts on a 4-kilogram object. What is the resulting acceleration?

Explanation:
Acceleration is found from F = m a, so a = F_net / m. With a net force of 8 N on a 4 kg object, the acceleration is 8 / 4 = 2 m/s^2. The motion speeds up in the same direction as the net force, and the units work out as m/s^2 because a Newton is defined as kg·m/s^2.
