What is the formula of total momentum?
_______________________________________________________ P = m x v P = momentum m= mass v = velocity _______________________________________________________ P t = P 1 x P 2 Total momentum = Momentum 1 X Momentum 2 Total momentum = ( mass x velocity of the first object ) x ( mass x velocity of the second object )
What is the momentum of a 100 kilogram boulder rolling south downhill at a velocity of 5 meters per second?
The idea is to multiply the mass by the velocity.
Why is the absolute value of speed equal to velocity?
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
How is the absolute value of velocity speed?
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
What is vector and resultant velocity?
A vector is used to represent direction and magnitude of speed. Velocity is the speed of an object and a specification of its direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. Therefore a vector can be used to represent a velocity. The term "resultant velocity" implies a change in velocity which can be determined using vector analysis.
As momentum of an object decreases what happens to the veocity?
An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum. Momentum is mass time velocity. Less velocity, less momentum. Technically, velocity is a vector and therefor momentum is a vector. One can speak of smaller or larger magnitudes of a vector, but not smaller and larger vectors because vectors have magnitude and direction. Speed is the magnitude of velocity.
A spaceship has a momentum of 20 000 kg-ms to the left and a mass of 500 kg What is the magnitude of its velocity?
momentum = mass x velocity, so velocity is momentum/mass. If the question asks for the magnitude then it's probably the absolute magnitude rather than a directional value (which would be negative as the space ship is heading to the left.
IF an objects veolicty is doubled its momentum is?
Use the symbols 'm' for the object's mass, and 'v' for its velocity. Momentum is defined as 'mv' = the product of the object's mass and velocity. If the velocity doubles, then the new momentum is 'm' times '2v' = 2mv = 2 times (mv). This is just double the original momentum. So you can see that the magnitude of momentum is directly proportional to the magnitude of velocity, provided the mass remains constant.
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.

Which of the following are vectors speed force mass displacement time velocity energy momentum?
force velocity displacement energy (has to have magnitude and direction)
Does a car traveling along a curved path at constant speed have a constant momentum?
No, the magnitude will be constant, but the direction of the momentum will change to reflect the direction of the velocity.
A spaceship has a momentum of 20000 kgms to the left and a mass of 500 kg What is the magnitude of its velocity?
80m/s
A scooter is moving with a speed of 18 ms. Its mass is 20 kg. What is the magnitude of its momentum?
Momentum is just mass times velocity. We assume that given that you can do the arithmetic.
What are the two factors which determine the momentum of a body?
Momentum depends on the mass and the velocity of an object. In physics, P=mv, momentum equals mass times velocity.
If a scooter has a mass of 20 kg and a velocity of 18 ms north what is the magnitude of its momentum?
360 kg/ms
If a person has a mass of 60 kg and a velocity of 2 m's what is the magnitude of his momentum?
