What else can I help you with?
Is the momentum of an electron constant?
No, the momentum of an electron can change depending on its velocity and direction of motion. Momentum is a vector quantity that is the product of an object's mass and velocity. So if the velocity of an electron changes, its momentum will also change.
In order to increase momentum we must increase either the object's?
mass or its velocity. Increasing the mass will increase momentum since momentum is directly proportional to mass, while increasing the velocity will also increase momentum since momentum is directly proportional to velocity.
Is momentum a measurement of the motion of something this is equal to the product of the moving objects mass times its velocity?
Yes, momentum is a measurement of the motion of an object, and it is equal to the product of the object's mass and its velocity. Momentum is a vector quantity, meaning it has both magnitude and direction.
Is momentum a scalar quality?
A vector quantity is one which transforms like the coordinates. In other words, if a coordinate system is transformed by an operator , any vector quantity in the old coordinate system can be transformed to its equivalent in the new system by the same operator. An example of a vector quantity is displacement (r). If displacement is a vector, the rate of change of displacement (dr/dt) or the velocity is also a vector. The mass of an object (M) is a scalar quantity. Multiplying a vector by a scalar yields a vector. So momentum, which is the mass multiplied by velocity, is also a vector. Momentum too transforms like the coordinates, much like any other vector. The definition of a vector as a quantity having "magnitude and direction" is simply wrong. For example, electric current has "magnitude and direction", but is a scalar and not a vector.
Relationship between acceleration and momentum?
No. Momentum is defined as mass times velocity, acceleration is the rate of change of velocity. To be more accurate, velocity is a vector quantity, it has both magnitude and direction. Momentum is therefore also a vector quantity in the direction of the velocity with magnitude equal to the mass times the magnitude of the velocity: 1) p = mv Acceleration is also a vector quantity and in the direction of the change in velocity direction and represents the rate of change of velocity: 2) a = dv/dt Force is defined as the rate of change of momentum, and is therefore also a vector in the direction of the momentum change: 3) F = dp/dt Substituting 1) in 3) we get: 4) F = m(dv/dt) And since 2) defines dv/dt as acceleration we get: 5) F = ma In other words, force is mass times acceleration. Note: The assumption above is that mass remains constant. This is an approximation that remains true only for slow speeds in comparison with the speed of light. These equations do not hold when approaching the speed of light as mass increases, and in fact makes it impossible to actually accelerate something to the speed of light.
Is the momentum of an electron constant?
No, the momentum of an electron can change depending on its velocity and direction of motion. Momentum is a vector quantity that is the product of an object's mass and velocity. So if the velocity of an electron changes, its momentum will also change.
What is the product of an object and the object's mass and velocity?
That's the object's linear momentum.
Is momentum a vector quantity because it includes velocity which is also a vector quantity?
yes, momentum is a vector quantity.
Is momentum a vector?
Momentum is a vector quantity because the definition of momentum is that it is an object's mass multiplied by velocity. Velocity is a vector quantity that has direction and the mass is scalar. When you multiply a vector by a scalar, it will result in a vector quantity.
If Momentum is a vector quantity because it includes velocity which is also a vector quantity?
= TRUE!
In order to increase momentum we must increase either the object's?
mass or its velocity. Increasing the mass will increase momentum since momentum is directly proportional to mass, while increasing the velocity will also increase momentum since momentum is directly proportional to velocity.
What is the law o conservation of momentum?
It means there is a quantity called "momentum", defined as velocity x time, that is conserved. That is, whatever interaction occurs, for example, objects bumping into other objects, the TOTAL momento will not change. In such bumping, momentum can be transferred from one object to another, of course. Note that since velocity is a vector, momentum is also a vector.

Does momentum have a direction?
Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.
Is momentum a factor in acceleration?
No. Momentum is defined as mass times velocity, acceleration is the rate of change of velocity. To be more accurate, velocity is a vector quantity, it has both magnitude and direction.
