Deceleration on a velocity-time graph is calculated by finding the slope of the line segment representing the decrease in velocity. The formula for deceleration is given by the change in velocity divided by the time taken for the velocity to change. It indicates how quickly the object is slowing down.

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.

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.
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 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
On a speed time graph what measures acceleration?
Acceleration on a speed-time graph is represented by the slope of the line. A steeper slope indicates a greater acceleration. If the slope is positive, it indicates acceleration; if it is negative, it indicates deceleration.
How do you find the minimum deceleration?
To find the minimum deceleration, you would need to calculate the change in velocity and time over which the deceleration occurs. Then, you can use the formula a = Δv / t, where a is the acceleration, Δv is the change in velocity, and t is the time. The minimum deceleration would be the smallest value calculated using this formula.
