Answer:
1. distance and period of time.
Explanation:
The speed is calculated using the formula
"k" is the speed, "d" is the distance and "t" is the time.
You need distance and time to calculate the speed.
Speed is how fast an object is going. The direction is irrelevant to speed, not to be confused with velocity, which is speed in a given direction.
The rotation axes of a car's wheels are horizontal and perpendicular to the direction of movement when the vehicle is moving ahead. The "direction" of the wheels' rotation, or more precisely, the direction of the angular velocity vector, is then uniquely specified by a mathematical convention.
<h3>Explain the rotation of the car's wheels and its direction?</h3>In other words, it is impossible to say whether an object is rotating clockwise or counterclockwise without also mentioning the angle from which the object is being viewed. The wheels would be said to be turning clockwise if the car passed you from left to right. However, someone on the opposite side of the street would claim that they were rotating the opposite way. However, both observers would concur on the definition of the angular velocity vector's direction.
<h3>What is angular velocity and axis of rotation?</h3>The symbol ω represents the magnitude of the angular velocity, which is equal to 2π divided by the duration of one rotation. In other words, ω = 2π / T. But what is important is the vector's orientation. And to do that, we employ the aforementioned "Right Hand Rule." Your right hand should be held with the thumb pointing in the direction of the rotation vector and the fingers curled in the direction the wheel turns.
In order to specify the angular velocity of each component that makes up the wheel with respect to the axis of rotation, a more formal definition uses a vector cross-product.
