Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

Question 3, conservation of momentum

### Transcription for Educational Website

#### Problem 3

**Before Collision:**
- **Object 1:**
- Mass: 6 kg
- Velocity: 5 m/s

- **Object 2:**
- Mass: 4 kg
- Velocity: 0 m/s

**After Collision:**
- **Object 1:**
- Mass: 6 kg
- Velocity: 1 m/s

- **Object 2:**
- Mass: 4 kg
- Velocity: ? m/s

Additional notes are handwritten indicating velocities:
- "5 m/s" is noted next to the velocity of Object 1.
- "0 m/s" is noted next to Object 2 before collision.
- "1 m/s" is noted next to Object 1 after collision.
- "? m/s" for Object 2 after collision.

A possible handwritten equation suggests: \( 30 + 0 = 6 \).

#### Problem 5

**Before:**
- **Person 1 on Skateboard:**
- Mass: 60 kg
- Velocity: ? m/s (indicated to the right)

- **Person 2 on Skateboard:**
- Mass: 40 kg
- Velocity: 0 m/s

**After:**
- Both persons are depicted together on skateboards, moving at a velocity of 1.5 m/s, indicated to the right with heart symbols, suggesting they are pleased or in agreement.

The diagram uses stick figures to represent people on skateboards before and after the interaction.

These scenarios can demonstrate conservation of momentum principles in physics, where the total momentum before and after a collision remains constant, assuming no external forces are at play.
