The ball falls, hits the road and does not roll.
It slows to a rest and then starts moving in the opposite direction at constant acceleration in that direction.
During reflection, the direction of light reverses. If light was traveling towards a reflective surface at a certain angle, it will bounce off the surface at an equal angle but in the opposite direction.
If velocity is zero and acceleration is negative, the object will start moving in the direction opposite to its previous motion. It will decelerate and eventually come to a stop before moving in the opposite direction.
You are either pushed the opposite direction of the current or go nowhere.
Air moves in opposite direction and if it's on a car-it will overheat
When you move the slide to the left, the image shifts to the right. This happens because the slide movement is in the opposite direction of the image movement, creating an apparent motion in the opposite direction.
If that happens, the body's speed will decrease.
1). Your speed in the forward direction should increase somewhat, since the recoil of the shot adds to your momentum. 2). The bullet you fire in the reverse direction leaves the muzzle with full muzzle velocity and momentum in the reverse direction ... in your frame of reference. Viewed by an observer in the stationary frame of reference ... the one in which you are moving at the speed of a bullet ... the one you fire just dribbles out of the muzzle and falls straight to the ground.
Maglevs don't effect birds except by hitting them.
When the direction of the current in a wire is reversed in a magnetic field, the direction of the force acting on the wire also reverses. This causes the wire to move in the opposite direction within the magnetic field.
Newton's third law of motion: every action has an equal and opposite reaction.
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
