Momentum is defined as mass * velocity, M=m*v.
Momentum: 200kg*m/sec
velocity: 2.5m/sec
mass: (200kg*m/sec) / (2.5m/sec) = 80kg
If remembering equations like these is difficult, then something useful for you would be to understand the concept of dimensional analysis. That is a fancy word for looking at the units of the given quantities. If you know that mass is kilograms, then you can figure out how to manipulate the units m/sec and kg*m/sec in order to come out with a final unit of kg. By dividing kg*m/sec with m/sec you end up getting (kg*m*sec) / (m*sec), leaving just kg left which is the unit you were looking for. Therefore you should divide 200 by 2.5 for a final answer of 80kg.
== == Momentum is the product of the mass of an object multiplied by its velocity (or speed). Momentum is conserved so if a moving object hits a staionary object the total momentum of the two objects after the collision is the same as the momentum of the original moving object.
momentum is the product of the velocity and mass: 250,000 kg m/s
No. To have kinetic energy, it must have both mass and velocity; the expression is Ek = 0.5mv2. To have momentum, something must also have mass and velocity; the expression for this is p = mv. Hence , if something has kinetic energy, you know it has momentum, and you can actually derive one from the other (provided you know the velocity); p = 2Ek/v.
The more the mass, the more momentum you will need for an object to speed up more, or accelerate.
if velocity increases, so does momentum. and vice versa momentum = mass x velocity increasing mass or velocity or both will increase momentum
77.5
If the mass is doubled,speed should be halved to conserve momentum.
The object's mass and speed.
Momentum is mass times velocity. Note that velocity and speed are not exactly the same thing. Velocity is a term used in physics to define both the speed and the direction of a moving object, so if two objects are moving at the same speed but in opposite directions, they have opposite momentum.
yes A moving vehicle has momentum according to it's mass and speed.
"Momentum" is the product of mass x velocity. You can base your calculations on that.
The Roller-skate Momentum = (mass) multiplied by (speed) . Anything moving has more momentum than anything that's not moving. The thing that's not moving has zero speed, so it also has zero momentum.
Momentum = mass x speed so speed = momentum/mass or V=P/m
Momentum is just mass times velocity. We assume that given that you can do the arithmetic.
NO .Momentum has some potential to do work where as speed is only the rate of action or travel. For example if a car is switched off while speeeding itwill still continue to run for some time due to momentum. Speed by itself has no energy for doing work Momentum is in fact defined as mass x velocity, and will be conserved in an elastic collision.
The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.
The slow moving train has a much higher mass than the high-speed bullet, but the bullet has a faster velocity than the slow moving train so their momentum is the same.
