How can I tell when two objects have the same velocity on a position graph?

If the position is graphed vs time, then the slope (rate of change of position with respect to time) will be the same (parallel).

Is a velocity graph the same thing as an acceleration graph?
Velocity is defined by physicists as both speed and direction, that is to say, if you are moving at 30 feet per second in a northerly direction, that is a velocity. Acceleration means a change in velocity. Physicists consider speeding up, slowing down, or changing direction all to be forms of acceleration; in more everyday usage, acceleration us used to mean speeding up and deceleration means slowing down. So, if your speed increases from 30 feet per second to 40 feet per second, that is acceleration.
Why do you measure bowler's throwing ball as speed but not velocity?
Speed and Velocity are the same thing, it is a measure of rate of change of position of an object.
What settings describe a displacement versus time graph?
Constant velocityZero acceleration and/or Moving object
What does a parallel line mean in position vs time graph?
A line parallel to the horizontal (time) axis usually indicates that the radial velocity of the object is zero, that is, the object is not moving towards or away from the origin. The object need not be still since it can be moving at any speed in a transverse direction. Two parallel lines indicate two objects, at different distances from the origin, gthat are moving at the same radial speed.
Why should you always measure position at the bottom hook of the spring rather than at the centre of mass of the attached load?
Because - the bottom of the hook will always be at the same position for objects of the same mass. Different sized objects may have the same mass - BUT - could have different centres of gravity.
How do you generate a position-time graph from a velocity time graph?
A girl walks along a straight path to drop a letter in the letterbox and comes back to his initial position. Her displacement-time graph. Plot a velocity-time graph for the same
The momentum of an objects is in the same what as its velocity?
In the same direction. Both momentum and velocity are vectors.
If two cars are traveling at the same time constant speed but in opposite directions explain how position vs time graph and the velocity vs time graph would be different?
Assuming position is measured between the cars and not their starting points?With constant speed the Distance over time graph would have a 1:1 slope or 45 degree angle.While the Velocity (which is constant) over time would be be a horizontal flat line.
What is the effect of changing the initial position on position time and velocity time graph?
Changing the initial position on a position vs time graph has no effect on the velocity vs time graph. Velocity is the derivative of position. This means velocity only depends on the rate of change (slope) of position. Changing the initial position of an object has no effect on the slope. Mathematically, this is equivalent to adding a constant to a function. Since the derivative of a constant is always 0, a change in initial position has no impact on the derivative. Here is an example. Say we have the position functions x(t)= 4+9t and y(t)= 27+9t. then the velocity function of x would be x'(t)=v(t)= 9 And the velocity function of y would be Y'(t)=v(t)= 9
Why all objects travel at the same velocity?
All objects do not travel at the same velocity. As an example, you should take a few minutes and think about an earthworm and a jet airliner.
To objects with the same velocity must be moving in the same?
Same speed, same direction.
Do two objects that have the same mass and velocity always have the same momentum?
yes
Do two skaters traveling in different directions at the same speed have the same velocity?
No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.
If two objects have the same velocity do they have the same momentum?
No, because momentum depends on velocity and mass so they may have the same velocity but if they have different masses then they will have different momenta. (momenta is the plural form of momentum.)
Who discovered that all objectsheavy or lightfall the same velocity?
Galileo Galilei was the first to explain that heavy and light objects would fall the same way in a vacuum. Keep in mind, objects do not fall with 'velocity,' but with 'acceleration.'
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
What two objects with the same velocity must be moving the same?
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.
