What happen to the speed when wavefront change direction?
When a wavefront changes direction, the speed of the wave remains the same. However, the direction of the wave's velocity vector changes as it propagates through different mediums or encounters obstacles.
What must happen for an object that is already moving to change its speed or direction?
For an object to change its speed or direction, a force must be applied to it. The magnitude and direction of the force will determine how the object's speed or direction changes. This change in motion is described by Newton's laws of motion.
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
How can velocity change even if speed stays the same?
Velocity is a vector quantity that includes both speed and direction. If the direction of motion changes while the speed remains constant, then the velocity will change. This can happen when an object moves in a circular path, for example.
Why do waves change speed and direction?
Waves change speed and direction when they encounter changes in the medium through which they are moving. This can be due to variations in the density, temperature, or composition of the medium. The interaction causes the wave to refract, reflect, or diffract, leading to changes in its speed and direction.

What is a change in velocity or direction?
Any change in speed or direction is a change in velocity. That's an acceleration,and it directly implies the presence of force, since it can't happen without force.
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
What change speed and direction depending on the density and materiel they travel through?
Waves.

Forces can change the what of movement of an object?
Forces can change the speed, direction, or both speed and direction of movement of an object.
What 3 things can happen when an object accelerates?
The object's speed can increase, leading to a higher rate of motion. The object's direction of motion can change, causing it to deviate from its original path. The object can experience a change in velocity, which is a combination of speed and direction.
Why does a change of speed produce a change in direction?
It doesn't. For example, you can go in a straight line, and speed up or slow down, without changing direction. And if there is both a change in direction and a change in speed, the change of speed wouldn't be the CAUSE for a change in direction. (On the other hand, both can be caused by a force applied to an object.)
What term refers to any change in speed direction or both?
Acceleration refers to any change in speed, direction, or both. It can be either an increase or decrease in speed, a change in direction, or a combination of both.
How does light passing through glass affect its speed and direction?
When light passes through glass, its speed decreases and it bends, or refracts, due to the change in the medium.
