Distance is described in units of meters and velocity is described in units of meters per second. So the difference between distance and velocity is that
velocity is divided by time
. With power and energy, power is units of energy divided by time. The same difference as distance and velocity.
What is the relationship between distance?
Velocity is the measure of the amount of distance an object covers in a given amount of time. Here’s a word equation that expresses the relationship between distance, velocity and time:
Velocity equals distance travelled divided by the time it takes to get there
.
Does distance affect power?
In electrostatics, the electrical force
between two charged objects is inversely related to the distance
of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. … Electrical forces are extremely sensitive to distance.
What is the relationship between power and work?
Work is referred to as the process of energy that is transferred to an object’s motion by applying force. It is generally represented as the product of displacement and force. Power is the amount of energy that is transferred in a unit of time. The formula for calculating the force is
Work = Force * Displacement.
What is relationship between power and time?
Power and time are
inversely proportional
.
Does current depends on distance?
The corresponding value depends on quantities such as the value of the current flow. Therefore,
there is no a specific general maximum distance
. … A conductor carrying current generates a magnetic field and a conductor moving within a magnetic field generates a current.
Does voltage drop with distance?
Any length or size of wires will have some resistance, and running a
current
through this dc resistance will cause the voltage to drop. As the length of the cable increases, so does its resistance and reactance increase in proportion. … This condition causes the load to work harder with less voltage pushing the current.
Does distance affect speed?
The faster an object
is moving, the longer the distance it takes to stop. If a vehicle’s speed doubles, it needs about 4X’s the distance to stop. … If you increase the weight of an object, you will also need increase the amount distance needed to stop.
What relationship exists between time and distance?
Velocity is the measure of the amount of distance an object covers in a given amount of time. Here’s a word equation that expresses the relationship between distance, velocity and time:
Velocity equals distance travelled divided by the time it takes to get there
.
What is the relationship of distance speed and time?
Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is
speed = distance ÷ time.
How are work and power similar and different?
Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement.
Power is the rate at which that work is done
.
Energy is what makes change happen and can be transferred form one object to another. …
Power is the rate at which energy is transferred
. It is not energy but is often confused with energy. The watt is the most commonly used unit of measure for power.
How do you find energy with power and time?
Power can be expressed as
P = Work/Change in Time
, instead of P = Change in Energy/Change in Time, because the change in energy is basically the work done.
What kind of relationship exists between force and power?
Force is the fundamental result of
an interaction between two objects
, while power is an expression of energy consumed over time (work), of which force is an element. Force and power can both be described and measured, but a force is an actual physical phenomenon, and power in itself is not.
What are the 3 equations for power?
P = ΔV
2
/ R
We now have three equations for electrical power, with two derived from the first using the Ohm’s law equation. These equations are often used in problems involving the computation of power from known values of electric potential difference (ΔV), current (I), and resistance (R).
