How are amplitude and velocity related?
velocity refers to speed of a particle in a particular direction. If your question is in context to waves or SHM, then velocity here refers to the speed at which the particles are vibrating and amplitude refers to the maximum distance covered by the particle from its mean position (position where acceleration is zero or velocity is maximum)
What is position velocity and acceleration?
POSITION, VELOCITY, AND ACCELERATION . Velocity, v(t), is the rate of change of position, s(t) vt s t ' Acceleration, a(t), is the rate of change of velocity (or the second derivative of position) at v t s t ' '' • Velocity indicates direction of movement (if v(t) > 0 the object is moving in the
How velocity and distance related are they proportional?
When you understand how they interact, and their equations; they are much easier to grasp. The relationship between distance and velocity is proportional. Distance = velocity x time If acceleration is involved in the question, the equation becomes Distance = v0 x t + 0.5 a t^2 Where v0 is original velocity.
What is relation between position and velocity?
The Position-Velocity Relation for a body moving in constant acceleration is given byv2=u2+2as.
How is position equation related to velocity equation?
To find velocity, take the derivative of your original position equation. Speed is the absolute value of velocity. Velocity accounts for the direction of movement, so it can be negative. It's like speed, but in a particular direction.
What is the relationship between position and velocity graphs?
The slope of the graph of position as a function of time is equal to the velocity at that time, and the slope of the graph of velocity as a function of time is equal to the acceleration.
How does position affect velocity?
A constant slope of a position-time graph indicates a constant velocity. A varying slope of a position-time graph indicates a changing velocity. The direction of the slope of the position-time graph indicates the sign of the velocity. For example, if it slopes downward, from left to right, the velocity is negative.
Is position the integral of velocity?
The integral of velocity with respect to time is position.

How is position velocity and acceleration related?
The derivative of position is velocity, the derivative of velocity is acceleration. So going in the reverse direction, and this is the way we're often going to go to have to go in.
Why is velocity the derivative of position?
Velocity is the change in position, so it's the slope of the position. Acceleration is the change in velocity, so it is the change in velocity. Since derivatives are about slope, that is how the derivative of position is velocity, and the derivative of velocity is acceleration.

Is position the derivative of velocity?
Derivatives with respect to time In physics, we are often looking at how things change over time: Velocity is the derivative of position with respect to time: v(t)=ddt(x(t)).
How do you find velocity from position vector?
Let r(t) be a differentiable vector valued function representing the position vector of a particle at time t. Then the velocity vector is the derivative of the position vector. v(t)=r′(t)=x′(t)ˆi+y′(t)ˆj+z′(t)ˆk.

How do you find velocity with time and position?
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.
Why is there a close relation between velocity and position?
There exist a very close relation between position and its velocity because the velocity is the rate of change of the position with respect to time. When the the position remains constant, the corresponding velocity is zero, as there is no change in position and basically the object remains at rest.
What is the position of a particle?
Position is the location of a particle as a function of time with respect to some fixed point called origin. For example, the position of a point P is 3 meter North of the Origin.
What is the instantaneous rate of change of an object with respect to time?
The instantaneous rate of change of an object with respect to time is the instantaneous velocity. In terms of Calculus, then, the derivative of displacement with respect to time is velocity. And, conversely, the integral of velocity with respect to time is the displacement, or change in position, as a function of time.
What type of acceleration is radial acceleration?
This type of acceleration is called radial acceleration, or centripetal acceleration.
What does it mean when you say acceleration in a straight line?
When talking about acceleration in a straight line, we say that “positive” acceleration increases the speed and “negative” acceleration, also called deceleration, decreases the speed.
What is the difference between displacement and distance?
Distance means the length of the path you moved while displacement is the difference between your initial and final position.
What is the x coordinate of the position?
For example: the x coordinate of the position is the integral of the x component of the velocity over time.
How to find velocity?
To find velocity, take the derivative of your original position equation. Speed is the absolute value of velocity. Velocity accounts for the direction of movement, so it can be negative. It’s like speed, but in a particular direction.
What does it mean when velocity is positive and decreasing at t = 1?
Since the velocity is positive and decreasing at t = 1 t=1 t = 1, that means that speed is also decreasing at that point.
How to determine if velocity is increasing or decreasing?
To determine whether velocity is increasing or decreasing, we plug 1 1 1 into the acceleration function , because that will give us the rate of change of velocity, since acceleration is the derivative of velocity.
How to find instantaneous velocity?
Given an equation that models an object’s position over time, s ( t) s (t) s ( t), we can take its derivative to get velocity, s ′ ( t) = v ( t) s' (t)=v (t) s ′ ( t) = v ( t). We can then plug in a specific value for time to calculate instantaneous velocity.
How to find acceleration?
To find acceleration, we take the derivative of the velocity function.
Can speed be negative?
Speed, on the other hand, can never be negative because it doesn’t account for direction, which is why speed is the absolute value of velocity. To find acceleration, take the derivative of velocity. Using the position function to find velocity and acceleration. YouTube. Take the course.
Heading to A Lake
- Velocity is a measure of speed, and essentially boils down to this equation: Velocity=change in distancechange in time.Velocity=change in distancechange in time. While you’re walking to the lake, you’re traveling at a rate of 2 miles every half hour (your change in distance is two, during t…
Other Examples of Derivatives
- Let’s see some other examples. Note for each of these, the position graphs is always piecewise linear, or made up of line segments. This makes it easier to find the velocity, or slope.
Integrals
- We can also go in the reverse direction: take a velocity graph, and create a position graph. This is called integration or taking an integral. This can be tricky but we can do it at this point if the function is what is called a step function, which is basically a function consisting of a bunch of flat parts. Going from velocity back to position is called an integral. Here is another example.
Increasing and Decreasing
- The following graphs are not made up of straight lines — but we can still tell if the derivative is positive or negative. A positive derivative means a quantity is increasing — and graphically that is represented by a graph the climbs as you go from left to right. A negative derivativemeans a quantity is getting smaller — graphically going downward from left to right. That’s right: (a) and (…
