What does conversation of momentum mean?
Conservation of momentum means that momentum is a constant and the change of momentum or force is zero.
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.
Why an object will move if its velocity is constant?
Momentum. If an object has constant velocity, the object will move because it has momentum. Momentum tends to stay the same unless changed by a force.
What is mean by consevation of momentum?
Conservation of momentum means the sum of Momentum is constant. Conservation of Momentum is the result of Conservation of Energy.
If the velocity is constant does that mean that the impulse is the momentum?
impulse = change in momentum so, no
a proton and electron have the same kinetic energywhich has longer wavelength?
the electron would have the longer wavelength b/c the proton has more momentum and λ=h/p (λ is wavelength, h is planc's constant and p is momentum)
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
Determine if the momentum of an object moving in a circular path at constant speed is constant.?
determine if the momentum of an object moving in a circular path at constant speed is constant.
If a particle moves in circle with constant speed its angular momentum about the center of circle?
The angular momentum is a constant.
What does conversation of momentum mean?
Conservation of momentum means that momentum is a constant and the change of momentum or force is zero.
Does an object have to be heavy in order to have momentum?
No. Even a single electron has momentum.
How angular momentum of the earth remain constant?
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
What does Ħ mean?
A modified form of Planck's constant called h-bar (ℏ), or the reduced Planck's constant, in which ℏ equals h divided by 2π, is the quantization of angular momentum. For example, the angular momentum of an electron bound to an atomic nucleus is quantized and can only be a multiple of h-bar.
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.
When is the mass of an electron regarded as zero?
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.
Why an object will move if its velocity is constant?
