When moving a wire downwards in a magnetic field, the induced electromotive force (emf) will be in one direction, whereas when moving the wire upwards, the emf will be in the opposite direction. This is due to the change in magnetic flux as the wire moves through the field in different directions, which results in the generation of emf in a direction that opposes the change in magnetic flux.

When object moves upwards what is the velocity and acceleration?
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
What is called a moving a body to face downwards?
Moving a body to face downwards is referred to as flipping or turning over.
What is the force that acts on a submarine?
Modern submarines move by using some sort of motor to drive a propellor (called a screw). The big u-boats have nuclear reactors that heat water to make steam, and have steam turbines that drive the screw through a big reduction gear. There are many smaller submarines that use a battery bank and electric motors with little propellors on them to move around.
When upward is positive then acceleration sign is?
Positive if the acceleration is also upwards directed, and if you are considering a one dimensional space where you thus only have upwards and downwards as directions. Otherwise you need to more information before you able to answer this question.
What force holds you to a sled when it starts moving?
The force that holds you to a sled when it starts moving is friction between your body and the sled, as well as the force of gravity acting on you downwards. As the sled accelerates, friction between your body and the sled helps keep you in place and in motion together.
When object moves upwards what is the velocity and acceleration?
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
What is accomplished by turning the coarse adjustment upwards downwards?
When turning the coarse adjustment on a microscope upwards or downwards, the distance between the tube and the stage changes. This changes the detail of what you can see of the specimen you are examining.
What is called a moving a body to face downwards?
Moving a body to face downwards is referred to as flipping or turning over.

What is the difference between downward and downwards?
"Downward" is an adjective used to describe the direction of movement, while "downwards" is an adverb that modifies a verb indicating a downward action. For example, "The elevator is moving downward" (adjective) versus "She looked downwards" (adverb).
Does plantar flexion mean turning the hand downward?
No. Plantarflexion refers to moving the ankle downwards. It is the opposite of dorsiflexion. Flexor Carpi Radialis is moving the wrist downwards.
Why was the smoke moving downwards when you put the dry ice in the hot cup of coffee?
Because of condensation between Ice and the hot coffee.
When something is thrown in the air it accelerates?
Something thrown in the air is affected by two factors: friction and gravity. Friction from the air, wind and whatever is in the air (such as dust) will slow it down making it decelerate from the direction it is moving. Gravity will cause the item to descend (move downwards). If moving upwards, it will slow down and then start moving downwards. It will accelerate downward at the rate of about 32 feet per second squared, or 32 feet per second per second. That means that an object (standing still) will be moving downwards at 32 feet per second after one second, at 64 feet per second after two second, 96 feet per seconds downwards after 3 seconds, and so on. It does not matter how heavy the item is.
What is one word for moving upwards?
Ascending.
Why would humans find it easier to push a load down a slope than upwards?
Humans find it easier to push a load down a slope than upwards because the force of gravity assists in moving the load downwards. This reduces the amount of effort required compared to pushing the load uphill where gravity acts against the motion.
When upward is positive then acceleration sign is?
Positive if the acceleration is also upwards directed, and if you are considering a one dimensional space where you thus only have upwards and downwards as directions. Otherwise you need to more information before you able to answer this question.
How does a simple pulley work?
A rope winds around the pulley so that two ropes hang downwards. Using one side of the rope to apply force causes the pulley to rotate and redirect the force, moving the load upwards even though the pull is applied downwards.
