Key Concepts in Physics

It represents the final velocity ($v$) of an object in motion, given its initial velocity ($u$), acceleration ($a$), and time ($t$).

Newton's second law states that the force ($F$) on an object is equal to its mass ($m$) multiplied by its acceleration ($a$), expressed as $F = ma$.

Kinetic energy is the energy of an object due to its motion, calculated using the formula $KE = \frac{1}{2}mv^2$.
