Answer 2

4. When the train stops, the passenger moves forward due to inertia.

5. Kinetic energy is a scalar quantity.

• Every object in motion will tend to continue in motion, this tendency is called inertia.
• Newton's first law of motion gives an idea about inertia.
• Kinetic energy is a scalar quantity as it requires no direction for defining it.
• It is the energy associated with motion.
• Kinetic energy = $\frac{1}{2}$ mv²
• V stands for velocity which is a vector quantity, but it is squared in the equation.
• The square of vector quantity becomes scalar.
