What else can I help you with?
Can any object have mechanical energy even if its momentum is zero. Explain?
Yes - mechanical energy includes both gravitational potential energy, and kinetic energy. If an object's momentum is zero, then its kinetic energy will also be zero, but its potential energy can be positive or negative, depending on whether the object is above or below the chosen reference level.
What is the energy during momentum?
There is no "energy during momentum". A moving object has both non-zero momentum, and non-zero kinetic energy.
Can you have kinetic energy without momentum?
We don't think you can. Here's our reasoning: -- Kinetic energy of an object is [(1/2)(mass)(speed)2]. If kinetic energy is not zero, then mass can't be zero, and speed can't be zero either. -- Momentum of the object is [(mass)(speed)]. If mass isn't zero and speed isn't zero, then momentum isn't zero.
Can a body have kinetic energy without having momentum?
Momentum = (mass) x (speed) Kinetic Energy = 1/2 (mass) x (speed)2 It looks like the only way a body can have zero momentum is to have either zero mass or else zero speed, and if either of those is zero, then that makes the KE also zero as well, too. So the answer to the question is apparently: no.
When ever an object is standing still the momentum is?
When an object is still it has no momentum. That is, the momentum is zero.
Is it possible for a person to have zero mechanical energy?
No, it is not possible for a person to have zero mechanical energy. Mechanical energy is the sum of an object's kinetic and potential energy, and as long as the person is in motion or has the potential to be in motion, they will have mechanical energy.
An object that has linear momentum must also have?
Momentum. The formula for kinetic energy is: KE = .5 * m *v^2 The formula for momentum is: p = m * v If an object has kinetic energy, then both mass and velocity are non-zero, which implies that the momentum is also non-zero.
Describe the momentum of objects at rest?
Measured in the frame of reference in which the object is at rest; zero since momentum is mass times velocity. Note that momentum is zero but inertia is not.
Does a stationary object have momentum?
No, a stationary object does not have momentum because momentum is the product of an object's mass and its velocity. If an object is not moving (velocity is zero), then its momentum will also be zero.
When does an object not have momentum?
An object does not have momentum when it is stationary or not in motion. Momentum is a product of an object's mass and velocity, so if either of these values is zero, the object's momentum will also be zero.
Does a resting object have momentum?
No, a resting object does not have momentum because momentum is the product of an object's mass and velocity. Since a resting object has zero velocity, its momentum is also zero.
How much momentum does an object at rest have?
An object at rest has zero momentum because momentum is the product of an object's mass and its velocity, and if the velocity is zero, then the momentum is also zero.
