Why is the graph of deceleration always curved?
The graph of deceleration is always curved because deceleration is a change in velocity over time, and velocity changes continuously as an object slows down. The rate of change in velocity (deceleration) is not constant but varies as the object slows down, resulting in a curved graph.
How is deceleration symbolized?
Deceleration can be symbolized as a negative value in an equation or graph, indicating a decrease in speed or velocity. It can also be represented by a downward sloping line on a velocity-time graph, showing a decrease in velocity over time.
How do you find the deceleration rate?
Deceleration rate can be calculated by dividing the initial velocity minus the final velocity by the time taken for the change in velocity to occur. The formula is: Deceleration = (Initial velocity - Final velocity) / Time. Alternatively, you can also calculate deceleration by dividing the negative change in velocity by the time taken for that change.
How do you calculate deceleration when time is not given?
Deceleration can't be calculated without knowing the time taken to decrease velocity. Deceleration is the rate at which an object slows down, given by the change in velocity over time. Without the time, the deceleration value cannot be determined.
What is the velocity time graph for a car first accelerating and then decelerating uniformly?
The velocity-time graph for a car first accelerating and then decelerating uniformly would have a positive slope during acceleration, representing an increase in velocity, and then a negative slope during deceleration, showing a decrease in velocity. The graph would form a "V" shape with two straight lines meeting at a point where the acceleration changes to deceleration.
Why is the graph of deceleration always curved?
The graph of deceleration is always curved because deceleration is a change in velocity over time, and velocity changes continuously as an object slows down. The rate of change in velocity (deceleration) is not constant but varies as the object slows down, resulting in a curved graph.

What physical quantity does the slope represent of a velocity time graph?
The slope of a velocity-time graph represents acceleration. A positive slope indicates an increase in velocity over time, while a negative slope indicates a decrease in velocity (deceleration). The steeper the slope, the greater the acceleration or deceleration experienced by the object.
How is deceleration represented on a velocity or time graph?

How do you calculate velocity from an x-t graph?
If an x-t graph is a position-time graph, velocity is the slope of the line on the graph.
What is the velocity time graph for a car first accelerating and then decelerating uniformly?
The velocity-time graph for a car first accelerating and then decelerating uniformly would have a positive slope during acceleration, representing an increase in velocity, and then a negative slope during deceleration, showing a decrease in velocity. The graph would form a "V" shape with two straight lines meeting at a point where the acceleration changes to deceleration.
How do you calculate deseleleration?
Deceleration (not deseleration) is the negative rate of change of velocity over time. Acceleration is [Final velocity - Initial Velocity]/Time. If the final velocity is less than the initial velocity, then the above quantity is negative and is termed deceleration. The instantaneous deceleration is dV/dt, the derivative of the velocity with respect to time. Sometime acceleration and deceleration are defined in terms of speed rather than velocity. This is not correct since it is inconsistent with the laws of motion.
What does it mean if the slopes of a velocity vs time graph slope goes up or down?
In a velocity vs. time graph, an upward slope indicates that an object's velocity is increasing, meaning it is accelerating. Conversely, a downward slope signifies that the object's velocity is decreasing, indicating deceleration. The steepness of the slope reflects the rate of acceleration or deceleration; a steeper slope corresponds to a greater change in velocity over time.
What does a curved line on a distance versus time graph tell you?
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
What is the meaning and formula for deceleration?
Deceleration is the rate of decrease of velocity with respect to time. It is the negative of acceleration. The formula for deceleration is the same as that of acceleration, only that the acceleration is represented as negative. The formula is: - (deceleration) = (final velocity) - (initial velocity) time Therefore, (deceleration) = (initial velocity) - (final velocity) time
