Does a person standing motionless in a aisle of a moving bus have kinetic energy?

Yes.
The person has a mass m and has the same velocity as the bus v,
so has a kinetic energy E, where
E = 1/2 * m *v^2
Obvioulsy, it all depends on your frame of reference, since this kinetic energy is due to the velocity of the person relative to the road due to the bus moving on that road at velocity v.

Does a person standing motionless in the aisle of a moving bus have kinetic energy?
Velocity depends on the point of view, or as they say in physics, on the "frame of reference". The amount of kinetic energy depends on velocity, and therefore, it also depends on the frame of reference.From the point of view of someone else who is also standing in the bus, such as person would have zero velocity and zero kinetic energy. From the point of view of one who watches the bus from the outside (standing still, near the road for example), the velocity, and therefore also the kinetic energy, of the person being considered will be non-zero.
Is a lit match kinetic or potential energy?
I think it is kinetic energy because it is moving and moving energy is kinetic energy.
Is a plane moving kinetic energy?
kinetic energy is motion energy, therefore any object that is moving possesses kinetic energy.
Is a match kinetic or potential energy?
I think it is kinetic energy because it is moving and moving energy is kinetic energy.
What do windmills convert into electrical energy?
kinetic energy. kinetic energy is moving energy and wind is moving.
What is the kinetic energy called when it is moving?
Kinetic energy is when it's moving. Potential energy is when the object is motionless.

Why does a jeepney continue to move for some time even after its engine has been switched off?
It's about inertia and kinetic energy. Everything that has mass will want to continue with what it's doing. If it's motionless, you have to overcome inertia to get it moving, and if it is moving, inertia will keep it moving until friction has used up all of its kinetic energy.

kinetic energy. kinetic energy is moving energy and wind is moving.
Why is cycling kinetic energy?
Kinetic energy is the energy of moving things, And a bicycle in use is a moving thing.
What is kinetic energy-?
Kinetic energy is energy that is posessed by a moving mass.
Is a hammer held above a nail kinetic energy?
No, the word 'Kinetic' literally means moving. So Kinetic energy literally means moving energy. If your hammer is above a nail then it is not moving... and so it is not kinetic energy.
