how are position velocity and acceleration related?
58801
The velocity of an object is found by taking the derivative of the position function: . Velocity can be thought of as the object's speed and direction, or change in position over time. The acceleration of an object is equal to the derivative of its velocity and describes the object's change in velocity over time.

If acceleration points in the same direction as the velocity, the object will be speeding up. And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

In one dimension, position is given as a function of x with respect to time, x(t). An object's change in position with respect to time is known as its displacement. ... The acceleration of an object is equal to the derivative of its velocity and describes the object's change in velocity over time.

Acceleration. Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Acceleration. When an object changes velocity, it accelerates. Acceleration is the change in velocity per second and is measured in m/s 2. The relationship between acceleration, velocity change and the time taken for the change is given by this formula. acceleration = change in velocity time taken = v - u t.

When velocity is changing, the word acceleration is used. Acceleration is also a vector. You speed up if the acceleration and velocity point in the same direction. You slow down (also referred to as decelerating) if the acceleration and velocity point in opposite directions.

Velocity includes both speed and direction of motion. Acceleration is a change in velocity. Velocity changes when either the speed, the direction, or both the speed and the direction change.

Terms in this set (22) Acceleration is increasing or decreasing speed or changing direction, whereas velocity is how much distance you cover in a given amount of time. What is the difference between constant velocity, instantaneous velocity and average velocity? Give an example of an object with constant acceleration.

If acceleration is in direction of velocity, the object speeds up. If acceleration and velocity are in opposite directions, the object slows down, and later reverses its velocity direction. ... In that case it's not in the direction of motion.

The relative velocities are the time derivatives of the position vectors. Therefore, →vPS=→vPS′+→vS′S. The velocity of a particle relative to S is equal to its velocity relative to S′ plus the velocity of S′ relative to S.

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

Velocity is vector: That means that going in one direction in velocity is not the same as going in the opposite direction. ... Acceleration is rate of change of Velocity: How quickly your velocity is increasing or decreasing. It is measured in meters per second per second, or m/s/s.

Velocity and acceleration are vector quantities, so they have both magnitude and direction. If the speed of an object remains the same but it changes direction, then the object is accelerating.

In essence… Velocity is directly proportional to time when acceleration is constant (v ∝ t). Displacement is proportional to time squared when acceleration is constant (∆s ∝ t2).

Acceleration is the derivative of velocity. Integrate acceleration to get velocity as a function of time. We've done this process before. We called the result the velocity-time relationship or the first equation of motion when acceleration was constant.
