Lesson Summary Momentum is mass in motion and only applies to objects in motion. It's a term that describes a relationship between the mass and velocity of an object, and we can see this when it is written in equation form, p = mv, where p is momentum, m is mass in kg and v is velocity in m/s.

The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.

Measure density by dividing the mass or weight of a sample by its volume. Written out, the formula for calculating density is: D = M/V, where D = density (g/mL), M = mass (g), and V = volume (mL).

The Linear Velocity can be found using the following formula: v=2π60⋅r⋅N v = 2 π 60 ⋅ r ⋅ N where: r = radius. N = number of revolutions per minute.

v 2−v 1=−e(u 2−u 1). This formula is Newton's law of restitution. The coefficient of restitution always satisfies 0≤e≤1. When e=0, the balls remain in contact after the collision.

Momentum is directly proportional to the object's mass and also its velocity. Thus the greater an object's mass or the greater its velocity, the greater its momentum. Momentum p is a vector having the same direction as the velocity v. The SI unit for momentum is kg · m/s.

The magnitude of the angular momentum of an orbiting object is equal to its linear momentum (product of its mass m and linear velocity v) times the perpendicular distance r from the centre of rotation to a line drawn in the direction of its instantaneous motion and passing through the object's centre of gravity, or ...

In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.

Momentum is not a scalar quantity. Momentum is a vector, which means it has a magnitude and a direction. Linear momentum is the product of an object's...

An object's mass and momentum are directly related; as mass increases, momentum will have a corresponding increase, assuming a constant velocity. Thus, an object with twice the mass of another object -- moving at the same speed and in the same direction -- will have twice the momentum.

English Language Learners Definition of momentum : the strength or force that something has when it is moving. : the strength or force that allows something to continue or to grow stronger or faster as time passes. physics : the property that a moving object has due to its mass and its motion.

Acceleration is the rate of change of velocity. Momentum is the mass times the velocity. So if you multiply the mass times the acceleration, you get the rate of change of momentum. ... Both are equal to mass times change in velocity divided by time.

The formula for the energy of motion is KE = . 5 × m × v2 where KE is kinetic energy in joules, m is mass in kilograms and v is velocity in meters per second.

Another formula, acceleration (a) equals change in velocity (Δv) divided by change in time (Δt), calculates the rate of change in velocity over time. This formula may be written a = Δv ÷ Δt. ... In science, the units for acceleration usually will be meters per second per second (m/s/s) or meters per second squared (m/s2).

The sum of the initial and final velocity is divided by 2 to find the average. The average velocity calculator uses the formula that shows the average velocity (v) equals the sum of the final velocity (v) and the initial velocity (u), divided by 2.

Linear momentum is mass multiplied by velocity, so it follows that angular momentum is the moment of inertia, measured in kilogram meters squared, multiplied by angular velocity, measured in radians per second. Radians are just an alternative to degrees.

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.
