What is Momentum?

Momentum is a fundamental concept in physics that describes the quantity of motion an object possesses. It is a vector quantity, which means it has both magnitude and direction. Momentum is defined as the product of an object’s mass (m) and its velocity (v).

All Formulae Related to Momentum Calculator

The formula for calculating momentum (p) is straightforward:

Momentum (p) = mass (m) × velocity (v)

Where:

• p represents the momentum of the object.
• m is the mass of the object (measured in kilograms, kg).
• v is the velocity of the object (measured in meters per second, m/s).

This formula allows you to calculate the momentum of an object when you know its mass and velocity. Here are some additional concepts and formulae related to momentum:

1. Impulse (J): Impulse is the change in momentum of an object and is calculated by multiplying the force (F) applied to the object by the time interval (Δt) over which the force is applied.Impulse (J) = Force (F) × Time Interval (Δt)The SI unit of impulse is newton-seconds (N·s), which is equivalent to kilogram meters per second (kg·m/s), the unit of momentum.
2. Newton’s Second Law: Momentum is related to Newton’s second law of motion, which states that the force applied to an object is equal to the rate of change of its momentum with respect to time.F = dp/dtWhere:
   • F is the force applied to the object.
   • dp/dt represents the derivative of momentum with respect to time.
   This equation shows that a force applied to an object results in a change in its momentum.
3. Conservation of Momentum: In a closed system (no external forces acting), the total momentum before a collision is equal to the total momentum after the collision. This principle is known as the law of conservation of momentum.Σp_initial = Σp_finalWhere:
   • Σp_initial is the total momentum before the collision.
   • Σp_final is the total momentum after the collision.
4. Relative Velocity: The relative velocity (v_rel) between two objects is used to calculate the relative momentum in a collision scenario. It is the difference in velocities of the two objects involved in the collision.Relative Velocity (v_rel) = v_1 – v_2Where:
   • v_rel is the relative velocity.
   • v_1 is the velocity of the first object.
   • v_2 is the velocity of the second object.
