## What is the momentum of a 1200kg car with a velocity of 25m s?

Answer and Explanation: We can find the momentum of the car by multiplying the mass times the velocity. Because both the mass and velocity are given in SI units, we do not need to perform any unit conversion before multiplying. Hence, we have shown that the momentum of the car is 30000 kg m/s.

## What is the formula for vehicle momentum?

p = m v . p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v).

## 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 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).

## What is the momentum of a 1500 kg car?

Therefore p=1500*20 = 30,000 kg m/s.

## 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} |

## Why do we calculate momentum?

Momentum gives the relationship between mass, velocity, and direction of an object. Any change in momentum results in force. So, a change in momentum is used to determine the force acting upon the object.

## What is the symbol for momentum?

Momentum | |
---|---|

Common symbols | p, p |

SI unit | kg⋅m/s |

Other units | slug⋅ft/s |

Conserved? | Yes |

## 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 M in physics?

Mass (symbolized m) is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram (kg).

## What is P in physics?

p = momentum m = mass v = velocity The definition of momentum. It is conserved (constant) if there are no external forces on a system.

## What is the SI unit of force?

The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.

## What is the momentum of 1000 kg car moving northward at 20 m?

p = mv = (1000kg)(20m/s) = 20000 kg m/s, northward • c.

## How do you find momentum from velocity?

The SI unit for momentum is kg • m/s. You can rearrange the equation to calculate velocity if you know momentum and mass, Velocity = Momentum/Mass, or to calculate mass if you know momentum and velocity, Mass = Momentum/Velocity.

## What is the momentum of a car traveling in a straight line at 20 m sec?

The momentum of a car traveling in a straight line at 20 m/sec is 24,500 kg·m/sec.

## Which has more momentum a 1000 kg car moving 1 m per second or a 70 kg person is printing at 8 m per second?

Expert-Verified Answer A 1000 kg car moving 1 m/s have more momentum which is 1000 kg meters per second.
