What is a true bearing?
A true bearing is a type of bearing that indicates the direction of one point relative to another point on the Earth's surface, measured using true north as a reference point. It is expressed as an angle, measured in degrees, between a fixed reference direction (such as true north) and the direction of the point being observed. True bearings are important for navigation, surveying, and other applications that require accurate direction-finding. They differ from magnetic bearings, which are measured relative to the Earth's magnetic field, and are subject to variation depending on the location and time. True bearings are more reliable and consistent, as they are based on the Earth's axis of rotation and do not change over time or location.
Why sine and cosine are functions of harmonic motion?
Simple harmonic motion (SHM( is defined by the second order differential equation: d2y/dt2 = -ky where y is a fubction of time, t and is the displacement (relative to the central position), and k is a positive constant. The equation says is that at any given position of the object undergoing SHM, its acceleration is proportional to its displacement from, and directed towards the central position. The sine and cosine functions are solutions to the differential equation.
What is the formula for the angular velocity?
There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
Why are sine and cosine functions called harmonic?
Sinusoid shape of the sine and cosine functions appear as oscillations. If an object is moving in a straight line and its position (function of time) can be described as sinusoid then it is referred to as a simple harmonic motion.
The sum of the braking distance and the perception and reaction time?
It is the total stopping time.
What is a change in position per unit time in a particular direction?
Velocity is the change in position per unit time in a particular direction. It includes both the speed and the direction of an object's motion.
What is the change in position divided by the time interval during which that change takes place?
The change in position divided by the time interval is known as velocity. Velocity is a vector quantity that specifies the rate of change of position of an object in a particular direction.
What is the velocity of an object at a particular moment in time?
The velocity of an object at a particular moment in time represents its speed and direction of motion at that instant. It is a vector quantity that can be determined by calculating the rate of change of its position with respect to time.
What term is defined as change in an objects position over time without including direction?
Motion is the change in an object's position without including direction.
What is the change in an objects position over time without including direction?
The change in an object's position over time without including direction is referred to as displacement. It is a vector quantity that represents the overall change in position of the object, regardless of the path taken.
A change in position over time is called what?
A change in position over time is called motion. It can be described in terms of speed, direction, and acceleration.
What is the change in position of an object with time?
The change in position of an object with time is known as displacement. It is the overall shift in location from the initial position to the final position, taking into account the direction of motion. Displacement is a vector quantity that includes both magnitude and direction.
What is the change in position in a given time?
The change in position in a given time is known as displacement. It is a vector quantity that describes an object's overall change in position and direction from its initial point to its final point. Displacement takes into account both distance and direction traveled by an object.
What is the ratio of change in position to the time interval during which the change is occured?
The ratio of change in position to the time interval is known as velocity. Velocity is a vector quantity that describes how fast an object's position changes and in what direction. It is calculated by dividing the change in position by the time interval.
What is the rate at which an object changes position in one direction?
The rate at which an object changes position in one direction is called velocity. It is a vector quantity that includes both the speed of the object and its direction of motion. Velocity is calculated as the change in position of the object with respect to time.
What is the change in an objects position over time without a direction?
Speed --- actually, if your question is 'position' over time, there is no answer since position is a vector quantity. And position divided by time will still yield a vector quantity-- velocity. If the question asks for change in distance over time, then the answer is speed. --gh ---
What is the velocity of a car that traveled a total of 75 kilometers north in 1.5 hours?
1.The time rate of change of position of a body in a particular direction 2. And by an arrow.
