Want this question answered?
The speed. Also, the wavelength, since the speed is equal to wavelength x frequency, and the frequency will normally NOT change.
the velocity of an object changes when it speeds up or slows down.
it change into potential energy beace it slows down
it changes because when it freezes, the molecules within the water slows down thus changing the placement of it, which also changes the over size or volume of water.
When a photon goes say from air to water, it slows down according to; n=c/v where n is refractive index of water c is velocity of light in air v is velocity of light in water It is stated that the frequency of the photon doesn't change when the photon enters the water. Only the wavelength changes.
the frequancy of a wave is always equal to the rate of vibration of the source that creates it.
It will not change. Glass slows light but does not change it frequency.

The kinetic energy of the object changes into thermal energy.

what happens when a moving object speeds up,slows down,or changes direction?
When the forces on an object are unbalanced the changes that could happen are the object speeds up, or slows down. And it can changes direction.
yes because momentum deals with motion and if an object slows down there is no motion or MOMENTUM
Any change in velocity, whether to speed up, slow down, or just change direction, results from acceleration. Acceleration is an expression of the rate of change of velocity.
