Instantaneous acceleration describes how fast a is changing at a specific instant?
Instantaneous acceleration is the rate at which an object's velocity is changing at a particular instant in time. It can be positive (speeding up), negative (slowing down), or zero (constant velocity). It is calculated as the derivative of velocity with respect to time.
What is positive and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
How is a negative acceleration different from a positive acceleration?
A negative acceleration refers to a decrease in velocity, while a positive acceleration refers to an increase in velocity. Negative acceleration occurs when the speed of an object is decreasing, such as when it is slowing down. Positive acceleration occurs when the speed of an object is increasing, such as when it is speeding up.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
What does the slope of the instantaneous speed-vs-time graph represented?
The slope of the instantaneous speed-vs-time graph represents the acceleration of the object. A positive slope indicates the object is accelerating in the positive direction, while a negative slope indicates acceleration in the negative direction. The steeper the slope, the greater the magnitude of the acceleration.
Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.

What is positive acceleration negative acceleration?
Positive is speeding up and negative is slowing down
What is negative and acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Difference between negative and positive acceration?
Positive acceleration ==> speeding up Negative acceleration ==> slowing down

The slope of a speed vs time graph is equal to what?
Acceleration.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
How do you show acceleration on a graph?
To show acceleration on a graph, you typically use a velocity-time graph where acceleration is represented by the slope of the line. A positive slope indicates positive acceleration, while a negative slope indicates deceleration. If the graph is a curve, the acceleration can vary, and the steepness of the curve at any point indicates the instantaneous acceleration. Alternatively, in a position-time graph, acceleration can be inferred from the curvature of the graph; a curved line suggests changing velocity, indicating acceleration.
