Acceleration is nothing but rate of increase in velocity. If acceleration at the time is positive velocity will increase independent of acceleration in past.
Suppose you are moving at 5m/s at t=0. Acceleration is 5m/s2 initially. At t = 1 your velocity will be 10m/s. If acceleration became 3m/s2, then your velocity at t = 2 will be 13m/s. Thus your velocity still increased but comparatively lesser in amount. Now if acceleration became -8m/s2, velocity at t = 3 will be 5m/s, thus velocity decrease due to negative acceleration.
What else can I help you with?
If a ball rolls down a hill does its speed or acceleration increase?
The speed of the ball increases as it rolls down the hill due to the acceleration caused by gravity. The ball will accelerate at a constant rate as it moves downhill, increasing its speed until it reaches the bottom of the hill.
When velocity is zero and acceleration is less than zero does the speed increase?
if acceleration is <0 and velocity =0 then you got the handbrake on
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
How does a change in speed affect acceleration?
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
Is it possible for the speed to increase at the same time the velocity decreases?
Yes, it is possible for speed to increase while velocity decreases if the direction of velocity changes. For example, if an object is moving in a circle, its velocity (speed and direction) changes constantly while its speed can increase or decrease depending on the acceleration.

What happens to acceleration when speed decreases on a speed time graph?
Acceleration is negative.
An objects acceleration decreases as the objects mass?
force = mass * acceleration then mass and acceleration is inversly proportional. Actually mass is constant but when the speed increases the mass become less since acceleration and velocity is directly propotional thus acceleration increases too.....thx..with best regards..
When velocity is zero and acceleration is less than zero does the speed increase?
if acceleration is <0 and velocity =0 then you got the handbrake on

Why speed increases if its acceleration decreases?

An increase in speed is sometimes called?
acceleration
What causes falling objects to speed up as they fall?
Falling objects speed up due to the acceleration of gravity acting on them. As an object falls, the force of gravity pulls it downward, causing it to accelerate. This acceleration causes the object to increase in speed until it reaches terminal velocity or hits the ground.
What is the definition of deceleration acceleration?
Deceleration is the rate at which an object slows down or decreases its speed. Acceleration is the rate at which an object speeds up or increases its velocity. Both are measures of how quickly an object's motion changes.
What is negative accelertion?
Acceleration is any change in velocity. Negative acceleration is when the change is such that the speed decreases.
