Speed plus direction is what?
Speed is a measure of how fast an object is going. This is a scalar quantity, which means it only gives magnitude (size) information. Velocity is a vector quantity, which is very similar to speed, but it also includes direction information.Example:Speed of car = 60 km/hVelocity of car = 60 km/h in a Northwesterly direction
How does the kinetic energy of a body change if its momentum is halved?
Since momentum is proportional to the velocity, half the momentum means half the velocity (and therefore half the speed). And since kinetic energy is proportional to the SQUARE of the speed, half the speed means 1/4 the kinetic energy.
How does velocity affect momentum?
if velocity increases, so does momentum. and vice versa momentum = mass x velocity increasing mass or velocity or both will increase momentum
What is the relationship between momentum and inertia?
I guess that momentum is part of the inertia, inertia is composed of momentum as the pages are related to the book. Inertia will be different if it has different kind of momentum. Force will affect momentum so inertia will change.
Can an object have momentum without speed?
No, it cannot. In the case of an object moving in the free space (no forces acting on the object) the energy consists of only the kinetic energy which is proportional to squared momentum. Thus, if the object has a momentum it has an energy to. Basically an object possesses some energy in any kind of time, and it might happen that the energy is zero. It doesn't mean that it has no energy. It means that the object has energy equals zero (which is not the same).
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.
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 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.
Is the momentum of the car travelling north different from the one of the same car when it travels south at the same speed?
Momentum is a vector. This means it has magnitude and direction. The magnitude will be the same. But the sign will be different. If north is positive, south will be negative. This is the only difference.
Spaceship 1 and Spaceship 2 have equal masses of 300 kg Spaceship 1 has a speed of 0 m s and Spaceship 2 has a speed of 4 m s What is the magnitude of their combined momentum?
Momentum = (speed) times (mass).Spaceship-1 has no momentum, since its speed is zero. The combined momentum is just the momentum of Spaceship-2.Momentum of Spaceship-2 = (m V) = 300 x 4 = 1,200 kg-meters
What has more momentum a car with a speed of 20 kmh or a car moving at 100 kmh?
The magnitude of momentum is directly proportional to speed. A car moving at 100 km per hr has 5 times as much momentum as a car with equal mass moving at 20 km per hr has.
What is the momentum of a truck with a mass of 4500 kg traveling at 25 m divided by s?
Magnitude of momentum = (mass) x (speed) = (4,500) x (25) = 112,500 kilogram-meters/second
Which of the following are vectors speed force mass displacement time velocity energy momentum?
force velocity displacement energy (has to have magnitude and direction)
Spaceship 1 and spaceship 2 have equal masses of 200 kg 1 has a speed of 0 ms and spaceship 2 has a speed of 10 ms what is the magnitude of their combined momentum?
2000
Does speed have magnitude only?
speed has magnitude. velocity has magnitude and direction.
Why 3000 kg mass moving at .2 m s has a big momentum?
Momentum in classical mechanics is defined as mass times velocity. The magnitude of the momentum of an object with mass 3000kg and speed 0.2 m/s has a momentum of 600 mkg/s. A human walking at the same speed of 0.2 m/s weighing, let's say, 100 kg has a momentum of 20 mkg/s which is 30 times smaller.
What is the average momentum of a 50 kg runner who covers 400m in 50 seconds?
Magnitude of momentum = (mass) x (speed)Mass = 50 kgSpeed = (400/50) meters per secondMagnitude of momentum = (50) x (400/50) = 400 kg-m/sec
