Does change in kinetic energy depends upon frame of reference?
The kinetic energy of any entity depends on the reference frame in which it is measured
. However, the total energy of an isolated system, i.e. one in which energy can neither enter nor leave, does not change over time in the reference frame in which it is measured.
Does kinetic energy depend on the frame of reference?
Yes. As you ride an express subway train, a backpack at your feet has no kinetic energy as measured by you since, according to you, the backpack is not moving.
In the frame of reference of someone on the side of the tracks as the train rolls by, the backpack is moving and has mass, and thus has kinetic energy.
Does energy change with reference frame?
Is change in kinetic energy frame independent?
Which depends on frame of reference?
The
magnetic force
depends on velocity which depends on the inertial frame of reference.
Is energy conserved in all reference frames?
In every inertial frame of reference, energy is conserved
.
In inertial frame of reference all Newton laws are valid, and since energy is defined as a work of the conservative force, energy should be conserved.
On what does kinetic energy depend?
Kinetic energy is a property of a moving object or particle and depends
not only on its motion but also on its mass
. The kind of motion may be translation (or motion along a path from one place to another), rotation about an axis, vibration, or any combination of motions.
Is total energy frame dependent?
No
. Potential energy is due to the presence of a body in a force field. Rest mass energy is the total energy a body has in a frame of reference where it is at rest.
Which of the following is independent of reference frame?
Sun is the center of mass of the solar system and is considered as inertial frame of reference except it motion is slow like
non inertial frames
but we can’t conduct any experiment to find its reference frame.
Which of the following do not depend on frame of reference?
<br> B :
Linear momentum
does not depend on frame of reference .
Which quantities does not depend on frame of reference?
A scalar
does not depend on the frame of reference.
Why force does not depend on frame of reference?
Originally Answered: Does force depend on frame of reference? Nonrelativistically, no, the force is a vector under rotations and nothing happens to it under Galilean boosts. The reason is that
adding a constant to the velocity doesn’t change the rate of change of velocity, which is the acceleration
.
Does a zero kinetic energy reference frame always exist never exist or sometimes exist?
Does a zero-kinetic energy reference frame always exist, never exist, or sometimes exist?
If all parts of the system have the same velocity, then there is a reference frame in which they are all at rest and have zero kinetic energy.
Is energy conserved in non inertial frames?
The paper demonstrates that for an object in arbitrary motion, the rate of work done due to fictitious forces affects the rate of change of the total energy. The fictitious work arises in the kinetic energy equation while
the internal energy and enthalpy equations remain invariant in the non-inertial frame
.
What 2 things does kinetic energy depend upon?
Explain that there are two factors that affect how much kinetic energy a moving object will have:
mass and speed
.
What factor does Ke depend?
K.E.=1/2 mv2 IT DEPENDS ON
MASS AND square of the VELOCITY
. IF ANY ONE IS INCREASED THAN KINETIC ENERGY IS ALSO INCREASED.
Is kinetic energy depends on mass of the body?
Thus kinetic energy of a body
depends on the mass of the body
as well as its velocity.
Is momentum frame dependent?
Is momentum the same in all reference frames?
Is kinetic energy the integral of momentum?
In short,
kinetic energy is indeed the integral of momentum with respect to velocity
. More accurately, the line integral of momentum with respect to the velocity vector at each point along a path gives the total change in kinetic energy. Physically, this represents the work done along the path.
Does a vector quantity depends upon frame of reference chosen?
no , a vector quantity is independent of frame of reference
.
Which of the following depends on the choice of inertial reference frame?
The
magnetic force
depends on v which depends on the inertial frame of reference.
Does Centre of mass depends on reference frame?
Is work reference frame dependent?
Does work done depend on the frame of reference?
Unequivocally, YES
. Forces are the same in any inertial reference frame, but displacements are not.
Does acceleration depend on reference frame?
Depends on the definition of frame. If by “frame” you mean inertial frame then yes acceleration is absolute. But we often still talk of accelerated frames of reference, so
acceleration is relative in that more expansive definition of frame
.
Is impulse frame dependent?
@K.T.
the fictitious force depends on your chosen frame
, so by varying how you choose the frame you can make your function Ff(t) have any form that you want. You could make your non-inertial frame rotate, or accelerate, or both, and have the rotation and accelerating vary with time.
Can kinetic energy ever be zero if so describe the motion of an object with zero kinetic energy?
Is it possible to be moving but have zero kinetic energy How?
Even the kinetic energy of the object is relative to the frame of reference where the velocity is measured.
If you are in a car moving at velocity v with respect to the road, it has zero kinetic energy in your frame of reference.
In what frame of reference would the total energy be equal to the rest energy?
Is linear momentum independent of frame of reference?
Is angular momentum frame dependent?
Angular momentum seems constant (
not dependent on chosen axis of rotation
) in an inertial frame where the center of mass is stationary.
Is momentum conserved in accelerating frame?
Is momentum the same in all reference frames?
No, the total momentum does not remain the same in different inertial frames of reference
. This is due to the fact that you can boost to a frame with different momentum (you don’t need special relativity for this, even basic treatment of relative velocities will do).
Does a zero kinetic energy reference frame always exist never exist or sometimes exist?
Does a zero-kinetic energy reference frame always exist, never exist, or sometimes exist?
If all parts of the system have the same velocity, then there is a reference frame in which they are all at rest and have zero kinetic energy.
In what frame of reference would the total energy be equal to the rest energy?
In the
inertial frame
in which such an object is at rest, however, the value of (gamma(v)) becomes 1 and the total energy is equal to the rest energy (E_o), one might say, precisely because in that inertial frame the object’s relativistic kinetic energy is zero.
