If two car are moving in the same direction and the velocity of car A exceeds the velocity of car B does it mean that car A's acceleration is greater than car B?
Not at all. In fact, if they're both moving at constant speed, then neither one has anyacceleration.
What you describe just means that the speed of one is greater than the speed of the other right now. If either one undergoes any acceleration, then either its speed or direction will change.
What else can I help you with?
Differentiate positive acceleration and negative acceleration?
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
What does the slope of a velocity vs time graph show you?
The rate of acceleration is a measure of the change of the velocity of an object with time. On a graph of velocity versus time, it is represented by the slope of the line so graphed. If velocity is changing in time, the object described is being accelerated. The greater the slope of the graph, the greater the change of velocity per unit of time and the greater the acceleration of that object. true
Can an object's acceleration be a negative number?
Yes, an object's acceleration can be a negative number if it is experiencing deceleration or moving in the opposite direction of its positive acceleration. Negative acceleration represents a decrease in velocity over time.
What does a positive slope on a velocity and time graph mean in terms of motion?
A positive slope on a velocity-time graph indicates that the object is moving in the positive direction (e.g., right or up) and experiencing a constant acceleration. The steeper the slope, the greater the acceleration of the object.
At what points does velocity change direction?
The velocity of an object can only change if it is accelerating and if this is constant and continuous. Velocity will also only change direction if acceleration is greater than zero and will not work if at zero.

Which is greater in positive acceleration initial or final velocity?
In positive acceleration, the final velocity is greater than the initial velocity. This is because acceleration is the rate of change of velocity, so as time progresses, the velocity increases due to the acceleration.
Can an object's acceleration be a negative number?
Yes, an object's acceleration can be a negative number if it is experiencing deceleration or moving in the opposite direction of its positive acceleration. Negative acceleration represents a decrease in velocity over time.

A positive slope on a velocity-time graph indicates that the object is moving in the positive direction (e.g., right or up) and experiencing a constant acceleration. The steeper the slope, the greater the acceleration of the object.

The velocity of an object can only change if it is accelerating and if this is constant and continuous. Velocity will also only change direction if acceleration is greater than zero and will not work if at zero.
What does acceleration depends on?
Acceleration is change in velocity. So it depends on both velocity and time.
When an object's initial velocity is less than its final velocity what does that indicate?
AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
What effects acceleration?
When an unbalanced force acts upon an object it will accelerate.
How is speed and acceleration related?
Speed is a scalar quantity that represents the rate at which an object is moving, while acceleration is a vector quantity that represents the rate of change of an object's velocity. Acceleration can affect the speed of an object by either increasing or decreasing it, depending on whether the acceleration is in the same direction as the object's motion or in the opposite direction. In general, the greater the acceleration, the faster an object's speed will change.
What force speed up moving object?
A force can speed up a moving object by accelerating it in the direction of the force. This acceleration increases the object's velocity, causing it to move faster. The greater the force applied, the greater the acceleration and resulting increase in speed.
What does the slope of a velocity time graph represent?
Slope just means "rate of change", so you can rephrase your question as "what do you call the rate of change in velocity over time?". When you look at it this way it's more apparent that the answer is acceleration. Hope this helps.
