vibrations
When sound moves forwards and backwards rapidly, it is called oscillation. This back-and-forth movement is what creates sound waves.
Primarily your Hip joint with its ball and socket, supplemented by the articulations of knee and ankle.
If an object is moving in the negative direction (backwards) and experiences a positive acceleration in the positive direction (forwards), it will slow down and decelerate. This is because the acceleration is acting in the opposite direction of the object's velocity, causing it to decrease.
Yes, it just depends on how you define which way is "positive". If you define the "backwards" direction to be the positive direction, acceleration will be positive when going "backwards". Note that if we define the axes like this, going "forwards" will give the car a negative acceleration.
When you rollerblade backwards you will essentially be moving your skates in a wave type motion. Both skates in towards each other, both skates out from each other. This constant motion will increase your speed as you go. As you learn the balance techniques of skating backwards, you can then work in doing backwards crossovers and turning.

by moving there legs forwards and backwards
the opposite of moving forward.
by moving your finger backwards and forwards all the time then afterwards you will feel a shake you will drop to the floor and you have hpnotised yourslef
by moving the camera backwards to make the person smaller or move the camera forwards to make the person bigger.

Stage 5 reverse osmosis looks similar to stage 4 reverse osmosis. It appears as though the cells are moving backwards when in fact they are moving forwards.
It should be moving forwards or backwards.
Their called epicycles
Possibly water resistance (drag)
Glaciers can move in any direction, including backwards, but typically they move in the direction of their accumulating mass (downhill). Factors such as changes in temperature, pressure, and topography can influence the direction of glacier movement.
Try just gently pushing the bike forwards or backwards - if it rolls freely it is in neutral, if it rolls a small amount before not moving any more it is in gear.
