Acceleration occurs when velocity changes over time. The formula for it is as follows:
a = (Vf - Vi) / t
a: acceleration (meters/seconds2)
Vf: Final velocity (meters/seconds)
Vi: Initial Velocity (meters/seconds)
t: Time (seconds)

∙ 6y agoIf the x-axis is time and the y-axis is location, the graph will be concave upwards because with positive acceleration, the second derivative of the graph is positive.
Another way to put it is that for x-axis as time and the y-axis as location, as you move in the positive x direction, the rate at which y goes up will increase - with the slope becoming more and more vertical.

What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
What is positive and negative acceleration?
Positive acceleration = speeding up. Negative acceleration = slowing down.
Is increasing acceleration the same as positive acceleration?
No. "Positive acceleration" means increasing speed. The acceleration is usually constantin typical Physics examples and applications.
Definition of acceleration?
increase rate in speed of acceleration
How is a negative acceleration different from a positive acceleration?
Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.
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.

Is increasing acceleration the same as positive acceleration?
No. "Positive acceleration" means increasing speed. The acceleration is usually constantin typical Physics examples and applications.
If the acceleration is increasing with time will the velocity graph be a straight line concave up or concave down?
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.
What is positive acceleration negative acceleration?
Positive is speeding up and negative is slowing down
Definition of acceleration?
increase rate in speed of acceleration
What can positive acceleration called?
Positive acceleration could be called "speeding up" if you felt like it.
How is a negative acceleration different from a positive acceleration?
Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.
Rate of change of velocity?
That's the definition of 'acceleration'.
Problems about positive acceleration?
Positive acceleration is an increase in velocity in the direction in which motion is being measured.
Another definition for acceleration?
Another definition for the word "acceleration" is "the rate of change of velocity per unit of time."
