Does acceleration refers to increasing speed decreasing speed or changing direction?

Acceleration refers to increasing or decreasing speed. When an object changes its speed, it is said to be accelerating, whether the speed is increasing or decreasing. Changing direction is related to a different aspect of motion called velocity.


Compare velocity from acceleration?

Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)


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 increasing acceleration the same as positive acceleration?

Yes, increasing acceleration means that the rate of change of velocity is increasing, which implies positive acceleration. Positive acceleration corresponds to speeding up, while negative acceleration (deceleration) corresponds to slowing down.


What three things can acceleration mean?

Increasing speed, decreasing speed, and change of direction


Can a body have decreasing acceleration but increasing speed?

Of course. The magnitude (size) of acceleration is the rate at which speed is changing. As long as the magnitude of acceleration is more than zero, speed is increasing. If the magnitude of acceleration is decreasing, then speed is growing more slowly, but it's still increasing. That's exactly what's happening to an object falling through air. As it falls faster and faster, the force of air resistance increases. The object's acceleration shrinks, and it's speed increases more slowly. When the force of air resistance is equal to the object's weight, the net force on it is zero, its acceleration is zero, and its speed stops increasing. It's then at 'terminal velocity'.


What is meant by positive acceleration and negative acceleration?

Positive acceleration = speeding up; speed increasing in the direction you're moving.Negative acceleration = slowing down; speed decreasing in the direction you're moving,or speed increasing in the opposite direction.


What is the verb for acceleration?

The verb for acceleration is "accelerate." It refers to the act of increasing the speed or rate of something.


What do you call the process of increasing speed?

The process of increasing speed is called acceleration. It measures how quickly the velocity of an object changes over time.


When is acceleration of an object positive?

Acceleration of an object is positive when its velocity is increasing over time. This means the object is speeding up in the direction of its motion.


If the speed of a car traveling south is increasing 5 ms it and its acceleration is?

If the speed of a car traveling south is increasing at 5 m/s, then its acceleration is 5 m/s². This acceleration indicates the rate at which the car's velocity is changing per unit time.


Why do engine looses acceleration after a certain speed?

Acceleration is the a change in speed or direction. Once a vehicle reaches a point where it is maintaining its speed but no longer increasing (or decreasing) the acceleration is zero. Even though you may be moving rapidly it is at a constant speed.
