# How do you tell if an object is moving towards the origin?

## How do you tell if an object is moving towards the origin?

The object moves along a straight line. At some time t, s(t) will tell me if the object is to the left or to the right of the origin. if if v(t) is +, then it is moving away from the origin. if v(t) is -, then it is moving back towards the origin.

How do you know the direction of the velocity for a moving object?

Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction. Objects have the same velocity only if they are moving at the same speed and in the same direction.

### Which velocity graph shows the car moving toward the right?

Which velocity graph shows the car moving toward the right (away from the origin) at a steady (constant) velocity? Explanation: Since the velocity is constant, the graph is a straight line. Since the car is moving to the right the velocity is positive.

How do you tell if a graph is moving left or right?

Thus, adding to the input of a function moves the graph left, and subtracting from the input of a function moves the graph right.

## What does the position time graph look like for an object moving with constant velocity?

The principle is that the slope of the line on a position-time graph reveals useful information about the velocity of the object. If the velocity is constant, then the slope is constant (i.e., a straight line). If the velocity is changing, then the slope is changing (i.e., a curved line).

Why do objects move in different velocity?

Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities. They represent objects that have different velocities only because they are moving in different directions.

### Does velocity Use direction?

Velocity is a vector quantity. As such, velocity is direction aware. When evaluating the velocity of an object, one must keep track of direction.

What does a velocity vs time graph tell you?

Velocity-Time Graphs Velocity vs. time graphs show how the velocity of a moving object changes over time. Because the slope of the position vs time graph tells you the object’s velocity, you can use it to create a velocity vs.

## How do you interpret a velocity-time graph?

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

Is acceleration a change in speed or velocity?

Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).
