Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
Does zero acceleration mean you are stopped?
Yes it does. Sources: 8 grade science textbook wikipedia
What happens to a falling object when the force of gravity equals to the force of air resistance?
the object will floatit shows increasing acceleration
What happens to acceleration when speed decreases on a speed time graph?
Acceleration is negative.
The slope of a speed vs time graph is equal to what?
Acceleration.
Does acceleration refers to increasing speed decreasing speed or changing direction?
Increasing speed
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.
Is increasing acceleration the same as positive acceleration?
No. "Positive acceleration" means increasing speed. The acceleration is usually constantin typical Physics examples and applications.
When is acceleration of an object positive?
When its speed is increasing
How is velocity of zero different from an acceleration of zero?
Velocity basically means how fast you are going. Acceleration means how much your speed is increasing. So if there is zero velocity that means the object is not moving. If there is zero acceleration, that means that the speed is not increasing but there is actual speed and the object is not increasing it's speed what ever that may be.
Compare velocity from acceleration?
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
In science acceleration refers to increasing speed decreasing speed or changing what?
Or Chaning Direction.
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'.
If a body dropped from rest has a constant acceleration in free fall is the distance traveled by the body the same for each time interval?
No. Acceleration is the rate at which the speed is INCREASING. Since the speed is increasing,the distance traveled by the body in each time interval is also increasing.
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.
A horizontal line on an acceleration graph would indicate?
-- constant acceleration -- speed increasing at a steady rate -- distance increasing as the square of the time since everything started
