Three ways that waves change direction are reflection, refraction, and diffraction.
When an object or a wave hits a surface through which it cannot pass, it bounces back. This interaction with a surface is called reflection.
When a wave enters a new medium at an angle, one side of the wave changes speed before the other side, causing the wave to bend. The bending of waves due to a change in speed is called refraction.
When a wave moves around a barrier or through an opening in a barrier, it bends and spreads out. These wave interactions are called diffraction.
No, refraction IS this change in direction. What it NEEDS, in order to happen, is a change in the refractive index, from one material to another.
To change the acceleration of a car: speed up, slow down or turn. Acceleration is any change in velocity. Velocity is "how fast" and in "what direction". To speed up is to accelerate (increase the velocity). To slow down is to deaccelerate (decrease the velocity) To turn is also a form of acceleration (changes the direction of the velocity).
If an object's speed changes, or it heads off in a new direction, its velocity has changed. Because of friction and gravity 1. acceleration 2. deceleration 3. change of direction
yes, because force is a push or pull, so an example would be that wind (the force) pushed the bike faster toward a building and steered the bike around the building, which causes the bike to change direction. This is an example of velocity too. Velocity is speed in a specific direction.
1. change the size of the force (eg. lots of cranking of car jack to lift car small amount). 2. change the speed 3. change direction of force (simple pulley - force one way, resistance moves in other direction)
EXAMPLES 1. Put a liquid in a different container 2. Crumple paper 3. Wrap up a cord 4. change hand gestures etc.
Three ways something can accelerate are 1. increase speed 2. change direction 3. both.

because when you change any two phases you change the direction of the current flow in the windings so you end up reversing the direction of the induced flux and the direction in which it acts
Change the Direction, Change the Speed and Change the Shape :)

1). increase of speed 2). decrease of speed 3). change of direction of motion
