a negative slope this is for my e2020 home boyz
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.
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.
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.
It is radial the velocity in a direction towards or away from a fixed point of reference (the origin) at a given time. The velocity time graph takes no account of motion in a direction across the radial direction.
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
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.
deceleration can be measured from a velocity time graph by calculating the gradient of the velocity time graph if the V-t graph was linear. If the v-t graph was a curve then the differentiatial of the equation of the curve will give the deceleration variation with time.
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.
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.
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
True. Velocity is the rate of change of displacement with respect to time, which is represented by the slope of the displacement versus time graph.
Acceleration and deceleration are related by their their sign. Acceleration is positive ( increase in velocity with time) and deceleration is negative (decrease in velocity with time).
