Positive velocity:
p=vt
(position = velocity*time)
Example: Write the position equation for a person who starts 3 meters behind the reference point and walks with a constant velocity v=6 m/s in the positive direction.
Answer: p=-3+6t
Example: What is the position of the person 5 seconds after the start of motion?
Answer: p=-3+(6x5)=27 m.
Negative velocity:
p=p(0)+vt
p(0) represents the position at time "0" which is also known as the y-intercept or the point where the line crosses the vertical axis. The velocity of the object in motion would be negative.

What is the formula for calculating displacement in which initial velocity and time are the variables?
If the velocity is constant, thenDisplacement = (initial velocity) multiplied by (time)
An object traveling at a constant 20 miles per second in a circular path is changing what?
This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.
Explain how distance time and velocity are related to each other?
They are related through the formula distance = time x velocity (assuming constant velocity).
Formula for distance traveled?
There is not enough information to answer the question. The answer depends onis the object travelling at constant velocity?is the acceleration constant?If it is an object travelling with constant acceleration, which three of the following four variables are knows: initaial velocity, final velocity, acceleration and time.
Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
If the velocity is constant describe the slope of the graph on a position vs. time graph.?
If velocity is constant, the slope of the graph on a position vs. time graph will be a straight line. The slope of this line will represent the constant velocity of the object.
What is the slope of constant velocity?
The slope of a position-time graph for an object moving with constant velocity is equal to the velocity of the object. This is because velocity is the rate of change of position with respect to time, and a constant velocity means the object is covering equal distances in equal time intervals.
What is an object that moves with constant position?
An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.
What is the formula for calculating displacement in which initial velocity and time are the variables?
If the velocity is constant, thenDisplacement = (initial velocity) multiplied by (time)
Is it true that particle with a position that is given by 𝑥(𝑡) 𝐴𝑡 plus 𝐵 (A and B are properly dimensioned constants) is moving with a constant velocity?
No, a particle with position given by 𝑥(𝑡) = 𝐴𝑡 + 𝐵 is not moving with constant velocity, it is moving with a constant acceleration since its position is changing linearly with time. Velocity would be given by the derivative of 𝑥(𝑡) which would be a constant.

How do you solve velocity?
Velocity is the rate of change of an object's position with respect to time. It can be calculated by dividing the change in position by the change in time. The formula for velocity is: velocity = displacement / time.
What was the relationship between velocity and time?
v = ds/dt where: v = velocity s = position t = time In other words, velocity is the rate of change of position. For the simplified case of constant velocity: v = (difference of position) / (time elapsed)
What is the formula of veocity?
The formula for velocity is velocity = distance / time. It represents the rate at which an object changes its position.
What is the formula for volcity?
The formula for velocity is velocity = distance/time. It measures the rate at which an object changes its position. Velocity is a vector quantity, meaning it has both magnitude and direction.
Formula fo linear velocity?
The formula for velocity is ds/dt where s (which is a function of time) is the position vector of the object at time t, and d/dt represents the derivative with regard to time.The formula for average velocity is (final position vector - starting position vector)/time.
Which graph represents an object moving with constant positive velocity?
A line with a positive slope on a position-time graph represents an object moving with constant positive velocity.
