which of the followinf describes how is force related to power
power divided by velocity is force
power times force is velocity
force divided by velocity is power
power time velocity is force
The correct answer is: power divided by velocity is force.
The correct statement that describes how force is related to power is:
Power divided by velocity is force.
The correct statement that describes the relationship between force and power is: "Power divided by velocity is force."
To understand why this is the case, let's break it down:
1. Power (P) is a measure of how quickly work is done or how much energy is transferred per unit of time. It is measured in watts (W).
2. Force (F), on the other hand, is the interaction that causes an object to accelerate or change its motion. It is measured in newtons (N).
3. Velocity (v) represents the speed of an object in a particular direction. It is measured in meters per second (m/s).
Now, based on the given statement, "Power divided by velocity is force," we can mathematically express it as:
P / v = F
This equation shows that force (F) can be calculated by dividing power (P) by velocity (v). In other words, if you know the power applied to an object and its velocity, you can determine the force acting upon it.
To better grasp the concept, let's consider an example. Suppose you're pushing a box with a power of 100 watts and it is moving at a velocity of 5 meters per second. By applying the equation:
P / v = F
Substituting the given values:
100 W / 5 m/s = F
The result will be an answer in newtons (force), which will give you a better understanding of the strength or intensity of the push or pull required to achieve the given power and velocity combination.
Remember, it's important to pay attention to the units in any equation to ensure a consistent and accurate calculation.
