Which describes what a velocity time graph would look like with no acceleration?
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 negative, then the slope is negative (i.e., a downward sloping line)..
Does constant velocity mean no acceleration?
An object with a constant acceleration should not be confused with an object with a constant velocity. … If an object is changing its velocity -whether by a constant amount or a varying amount – then it is an accelerating object. And an object with a constant velocity is not accelerating.
In what situation does the velocity time graph have a straight line with a negative slope?
In retarded motion the velocity time graph is a straight line with negative slope. Explanation: Negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be negative.
What does no motion look like on a graph?
DISTANCE-TIME GRAPHS If an object is not moving, a horizontal line is shown on a distance-time graph. Time is always plotted on the X-axis (bottom of the graph). The further to the right on the axis, the longer the time from the start.
What does constant velocity look like on a velocity vs time graph?
In a velocity-time graph, acceleration is represented by the slope, or steepness, of the graph line. … If the line is horizontal, as it is between 4 and 7 seconds, velocity is constant and acceleration is zero.
Which part of the graph represents constant velocity?
A horizontal line on a speed-time graph represents a constant speed. A sloping line on a speed-time graph represents an acceleration. The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down.
How do you describe a velocity time graph?
Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. The object may change direction, eg from forward to backwards, up or down, left or right. … The positive section of the graph represents the forward direction; the negative section represents the opposite direction.
What does the slope of velocity time graph indicate?
What does the slope represent on a velocity graph? The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
How do you calculate the distance on a velocity time graph?
Calculating the distance travelledCalculate the total distance travelled by the object – its motion is represented by the velocity-time graph below.Here, the distance travelled can be found by calculating the total area of the shaded sections below the line.½ × base × height.½ × 4 × 8 = 16 m 2(10 – 4) × 8 = 48 m 2More items…
How do you determine velocity?
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.
Can a body have acceleration with constant velocity?
The velocity vector is constant in magnitude but changing in direction. Because the speed is constant for such a motion, many students have the misconception that there is no acceleration. … For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating.
Can acceleration change if velocity is constant?
An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. If an object’s velocity is constant, however, its acceleration will be zero. … Since it travels in a straight line, its direction does not change.
What does constant speed look like on a graph?
Constant speed is shown by straight lines on a graph. steeper dashed line got there before the other one: A steeper line indicates a larger distance moved in a given time. In other words, higher speed. Both lines are straight, so both speeds are constant.
What does a straight line mean on a velocity time graph?
On a velocity-time graph a horizontal (flat) line indicates the object is travelling at a constant speed. A straight diagonal line indicates the object’s velocity is changing.
Which graph shows a negative acceleration?
The velocity-time graph shows a line with a negative (downward) slope (negative acceleration); the line is located in the positive region of the graph (positive velocity).
What is an example of constant velocity?
Answer to Essential Question 2.3: Some examples of constant velocity (or at least almost- constant velocity) motion include (among many others): • A car traveling at constant speed without changing direction. A hockey puck sliding across ice. A space probe that is drifting through interstellar space.
How can you tell if a velocity graph is constant?
If you are given a velocity graph and it is horizontal (blue and green lines below), then the velocity is constant. If the graph is anything but horizontal, then the velocity is not constant. If you are given an acceleration function or graph and it is zero (green line below), then the velocity is constant.
What does a vertical line mean on a velocity time graph?
A vertical line (a line parallel to the Y-axis) has an infinite slope. It means that the particle is having an instantaneous change in velocity. … Initial velocity is above the origin in a velocity time graph.
