What else can I help you with?
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.
Is your speed constant if you are traveling in a straight line with an acceleration of zero?
Yes as there is no acceleration then the speed which is already there would remain the same as no change in speed is brought out.
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.
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'.
Compare velocity from acceleration?
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
How is increasing speed acceleration?
By definition acceleration is the change in velocity (speed).
Does zero acceleration mean you are stopped?
Yes it does. Sources: 8 grade science textbook wikipedia
A car is traveling south at a speed of 68 miles per hour and then begins traveling at a speed of 69 miles per hour but continues traveling in the same direction What has changed?
Both the speed and velocity have increased as a result of acceleration.
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.
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Is your speed constant if you are traveling in a straight line with an acceleration of zero?
Yes as there is no acceleration then the speed which is already there would remain the same as no change in speed is brought out.
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.)
What is the acceleration of car that travels in a straight line at constant speed?
Straight line at a constant speed = no acceleration
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
