## What is the formula for total momentum?

The total momentum (ptot) of a system is equal to the sum of the momenta of all objects within that system. p t o t = p 1 + p 2 + p 3 + . . . Furthermore, the momentum of each of the individual objects in the system is equal to the mass (m) of that object multiplied by its velocity (v).

## Why the successful tackle constitutes a perfectly inelastic collision?

A successful tackle is a perfectly inelastic collision because of the players involved in the collision stick together and moves with the same velocity after the collision. Some mechanical energy loss occurs in the case of perfectly inelastic collision.

## What are the 2 equations for momentum?

Momentum (P) is equal to mass (M) times velocity (v). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (ΔP) over the change in time (Δt).

## How to find momentum?

Step 1: List the mass and velocity of the object. Step 2: Convert any values into SI units (kg, m, s). Step 3: Multiply the mass and velocity of the object together to get the momentum of the object.

## What if collision is perfectly elastic?

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions.

## What is perfectly inelastic velocity?

Inelastic collisions occur when only the momentum is conserved but not the kinetic energy of the system. Perfectly inelastic collisions happen when object stick together and have a common velocity after collision. To solve for the final velocity in perfectly inelastic collisions, use v’ = (m1v1 + m2v2)/m1 + m2.

## What is perfectly inelastic collision answer?

A collision in which the objects stick together is sometimes called a perfectly inelastic collision because it reduces internal kinetic energy more than does any other type of inelastic collision. In fact, such a collision reduces internal kinetic energy to the minimum it can have while still conserving momentum.

## What is SI unit of momentum?

Momentum | |

SI unit | kilogram meter per second (kg⋅m/s) |

Common symbols | p, p |

Other units | slug⋅ft/s |

Dimension | MLT^{−}^{1} |

## Is momentum is a vector?

The momentum of a body is a vector quantity, for it is the product of mass, a scalar, by velocity, a vector.

## Why is P used for momentum?

This meaning is also related to the word ‘impetus’ which is the earlier term used for ‘momentum’. The word ‘impetus’ gives the meaning as to go and rush upon which was explained by the term Petere. Hence, momentum is represented by the letter P.

## What is the formula for total momentum Class 9?

The product of the units of mass and velocity is the unit of Momentum. To find the momentum, we can use the simple formula: P=mv, where P is the momentum.

## What is the total momentum?

Momentum is equal to the mass of an object multiplied by its velocity and is equivalent to the force required to bring the object to a stop in a unit length of time. For any array of several objects, the total momentum is the sum of the individual momenta.

## What is the formula for total energy and momentum?

Connection to E = mc2 The energy–momentum relation is consistent with the familiar mass–energy relation in both its interpretations: E = mc2 relates total energy E to the (total) relativistic mass m (alternatively denoted mrel or mtot ), while E0 = m0c2 relates rest energy E0 to (invariant) rest mass m0.

## What is the unit of total momentum?

In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.
