Question

State the usefullness of newton second law of motion

Answer 1

Newton's Second Law of Motion $\left({\overrightarrow{\mathrm{F}}}_{\mathrm{net}}=\mathrm{m}\overrightarrow{\mathrm{a}}\right)$ is very important because it shows the relationship between forces and motion. It allows you to calculate the acceleration (and therefore velocity and position) of an object with known forces.
