ACTIVITY 1. Exploring More About Relativistic Mass

Answer the following questions (briefly) to check your understanding:

1. Why is not possible for any object to move faster than the speed of light? Explain this in terms of momentum concepts.

2. What happens to relativistic momentum at low velocities? What postulate of special relativity does this prove?

ACTIVITY 2. Understanding the Relationship of Relativistic Mass, Momentum & Energy

Answer the following questions (briefly) to check your understanding:

1. What is the formula of relativistic kinetic energy?

2. How is relativistic kinetic energy different to your classical kinetic energy formula, KE = mv²?

3. What happens to relativistic kinetic energy at low velocities? Explain the significance of this.

4. No object with mass can attain the speed of light, because an infinite amount of work and an infinite amount of energy input is required to accelerate a mass to the speed of light. Is this correct? Why?

5. How should we define relativistic energy so that it could be conserved?

ACTIVITY 3. Knowing More About E = mc²

Answer the following questions (briefly) to check your understanding:

1. What do we mean by E = mc²?

2.How did Albert Einstein formulate it?

3.What are its applications?
