POSITIVE
is moves with a constant velocity in the positive direction......
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
No. It is false. But if you change the word "negative" to read "positive" instead, then your entire statement will become true.
clockwise
work is said to be positive when both the force and displacement is acting on the same direction
It is a positive wave in the hearts muscle cells, the process of electrical discharge and the flow of electrical activity.
During depolarization, sodium ions rush into the axon, making the inside negative, and the outside positive.
The P wave on ECG corresponds to electrical depolarization of the atria. It should be positive in lead II and negative in aVR when the P wave originates in the sinoatrial node.
Negative to positive.
Neurons send messages electrochemically and all chemicals in the body are electrically-charged. When neurons inside the body are electrically-charged, they are called ions. When a neuron is at rest, or not electrically-charged, the inside is negative and the outside is positive.
becoming more positive
Depolarization.
k, na, ca, mg
Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.
Positive electrical flow is electrons flowing in one direction in a wire, if they change the direction of flow that would be a negative flow. If they change direction quickly, say 60 times a second, that would be alternating current, which is what we have in the united states as household electricity.
Electrical current flow through a circuit is normally from negative toward positive.
It depends if they have the same positive slope if yes then they are parallel.
