1. What is Momentum Ratio Calculation?

The momentum ratio calculation determines how momentum changes when the velocity of an object is doubled. Since momentum (p) is directly proportional to velocity (v), doubling the velocity results in doubling the momentum.

2. How Does the Calculator Work?

The calculator uses the momentum ratio formula:

Where:

• \( p_1 \) — Initial momentum
• \( p_2 \) — Final momentum
• \( v_1 \) — Initial velocity
• \( v_2 \) — Final velocity (2 × v1)

Explanation: The formula shows that momentum is directly proportional to velocity. When velocity doubles, momentum also doubles, maintaining the same ratio of 2:1.

3. Importance of Momentum Ratio

Details: Understanding momentum changes is crucial in physics, engineering, and collision analysis. It helps predict how changes in velocity affect an object's momentum and the resulting forces in interactions.

4. Using the Calculator

Tips: Enter the initial velocity in m/s. The calculator will automatically compute both the momentum ratio and velocity ratio, which will both equal 2 when velocity is doubled.

5. Frequently Asked Questions (FAQ)

Q1: Why does momentum double when velocity doubles?
A: Because momentum (p) is calculated as mass × velocity (p = m×v). If mass remains constant, momentum is directly proportional to velocity.

Q2: Does this ratio change if mass changes?
A: This specific calculation assumes constant mass. If mass also changes, the momentum ratio would be affected by both velocity and mass changes.

Q3: What are the units for momentum ratio?
A: The momentum ratio is dimensionless since it's a ratio of two momentum values with the same units.

Q4: Can this be applied to rotational motion?
A: For angular momentum, the relationship is more complex and depends on both rotational velocity and moment of inertia.

Q5: How does this relate to kinetic energy?
A: While momentum doubles with doubled velocity, kinetic energy (KE = ½mv²) increases by a factor of 4 when velocity doubles.
