There are two **kinds of momentum**, linear and angular. A spinning object has angular **momentum**; an object traveling with a velocity has linear **momentum**. For now, and throughout chapter 7, we'll deal with linear **momentum**, and just refer to it as **momentum**, without the linear.20 oct. 1999

In addition to, which type of quantities are force and momentum?

**Momentum** changes with the change in velocity whereas **force** changes with the change in acceleration. The longer a **force** is applied, the larger the **momentum** is. Both of these **quantities** are vector **quantities** meaning they both have magnitude and direction.

Else, what is momentum the same as? **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** (ฮP) over the change in time (ฮt). And the change in **momentum** (ฮP) is also equal to the impulse (J).

Along, what is momentum of a body?

**Momentum** is the product of the mass of a particle and its velocity. ... Conversely, the **momentum** of a particle is a measure of the time required for a constant force to bring it to rest. The **momentum** of a rigid **body** is the sum of the momenta of each particle in the **body**.

What is momentum and its unit?

**Momentum**. If the mass of an object is m and it has a velocity v, then the **momentum** of the object is defined to be **its** mass multiplied by **its** velocity. **momentum**= mv. **Momentum** has both magnitude and direction and thus is a vector quantity. The **units** of **momentum** are kg m sโ1 or newton seconds, N s.

Scientists **calculate momentum** by multiplying the mass of the object by the velocity of the object. It is an indication of how hard it would be to stop the object. If you were running, you might have a mass of 50 kilograms and a velocity of 10 meters per second west (really fast).

scalar quantity

Like moving particles, **waves have momentum**. However the existence of wave **momentum** should not cause doubt, although it is less noticeable than wave energy. For example, the light pressure of the Sun's radiation on the Earth orbit is very small, p = 4.5 ยท 10-7 Pa [1, 2].

Air bags are used in automobiles because they are able to minimize the effect of the force on an **object** involved in a collision. Air bags accomplish this by extending the time required to stop the momentum of the driver and passenger.

A way to think about **momentum** is to consider how difficult it would be to stop an object in motion. An object that is bigger or going faster can be said to have **momentum** equal to mass x speed (velocity). An example of this would be to compare how difficult it would be to stop a car that is going 35 mph.

The **energy**โ**momentum** relation is consistent with the familiar massโ**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.

The newton-second (also newton second; symbol: Nโ
s or N s) is the derived SI **unit** of impulse. It is dimensionally equivalent to the **momentum unit** kilogram-metre per second (kgโ
m/s). One newton-second corresponds to a one-newton force applied for one second.

The impulse experienced by the object equals the **change in momentum** of the object. In **equation** form, F t = m ฮ v. In a collision, objects experience an impulse; the impulse causes and is equal to the **change in momentum**.

Appropriate MKS or SI units for angular momentum are **kilogram** metres squared per **second** (**kg**-m2/sec). For a given object or system isolated from external forces, the total angular momentum is a constant, a fact that is known as the law of conservation of angular momentum.21 sept. 2018
