What is the dimension of momentum and density?
Dimensions of Some Physical Quantities:
| Sr.No. | Derived Quantity | Dimensions |
|---|---|---|
| 3 | Density | [L-3M1T0] |
| 4 | Velocity | [L1M0T-1] |
| 5 | Acceleration | [L1M0T-2] |
| 6 | Momentum | [L1M1T-1] |
Does momentum and impulse have the same dimension?
We will determine the dimensional formula of every given quantities option wise. Therefore, impulse and momentum have the same dimensional formula.
How is the formula for momentum derived?
In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Newton’s second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

| Dimension | M L2 |
What is the dimension of linear momentum?
Therefore, linear momentum is dimensionally represented as [M1 L1 T-1].
Which of the following is formula for 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).
What is meant by momentum formula?
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. Momentum = mass • velocity. In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as p = m • v. where m is the mass and v is the velocity.
What is the equation used to calculate momentum?
The formula for calculating momentum is mass multiplied by velocity. An object’s momentum is equivalent to its mass times its velocity, therefore the equation for momentum is the same. Momentum is measured in kilogram-meters per second, which are all standard metric units.
What are the units of measurements for momentum?
The unit of momentum is the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity is in meters per second then the momentum is in kilogram meters per second (kg⋅m/s).
What is momentum and how is it calculated?
Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity) times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion.
What are the two factors of momentum?
Two factors affecting momentum is the mass and velocity of the object. An object that has a low velocity and a small mass produce minimal momentum because it would take a small force and/or time to stop it. Likewise a heavy object traveling at high speed will have a large momentum as it will take a large force and/or time to stop it.
