Velocity is defined by physicists as both speed and direction, that is to say, if you are moving at 30 feet per second in a northerly direction, that is a velocity. Acceleration means a change in velocity. Physicists consider speeding up, slowing down, or changing direction all to be forms of acceleration; in more everyday usage, acceleration us used to mean speeding up and deceleration means slowing down. So, if your speed increases from 30 feet per second to 40 feet per second, that is acceleration.

No, a velocity graph shows changes in an object's velocity over time, while an acceleration graph shows changes in an object's acceleration over time. Velocity is the rate of change of position, while acceleration is the rate of change of velocity.

Velocity is displacement divided by time.
Acceleration is velocity divided by time.
However both graphs are related! If you graph the AREA under the slope of the acceleration graph vs. time, this will be a velocity graph. If you graph the SLOPE of the velocity graph vs. time, this will be an acceleration graph.
When you learn calculus (unless you already know it) you will learn how you can switch between the two.

What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
What is the acceleration?
Acceleration is the rate at which an object changes its velocity. It can be calculated by dividing the change in velocity by the time taken for that change to occur. Acceleration can be in the same direction as the velocity (speeding up) or in the opposite direction (slowing down).
What interpretation can you derive regarding the motion from the graph of instantaneous speed vs time graph?
The slope of the instantaneous speed vs. time graph gives the acceleration of the object. A horizontal line indicates constant speed, a positive slope indicates acceleration, and a negative slope indicates deceleration. Changes in the slope indicate changes in acceleration.
How can a position time graph show if an object has constant acceleration?
A position-time graph with a straight line indicates constant acceleration. The slope of the line represents the acceleration, which is constant if the slope remains the same throughout the graph. A steeper slope indicates a greater acceleration, while a shallower slope indicates a smaller acceleration.
Why is acceleration a factor in force and not velocity?
Acceleration is a factor in force because force is defined as the rate of change of momentum, which involves mass and acceleration. Velocity is the rate of change of position, and on its own does not impact force in the same way acceleration does. Acceleration directly affects the change in an object's velocity, which in turn influences the force required to produce that change.
What characterizes constant velocity motion on a velocity-time graph?
On a velocity-time graph, constant velocity motion is characterized by a horizontal line where the velocity remains the same over time. The slope of the line is zero, indicating that the acceleration is zero and the object is moving at a steady speed.
What does the slope of a line on a velocity vs time graph represent?
The slope of the line of a speed-versus-time graph will give you acceleration. Remember that acceleration may be positive or negative, and in some cases, acceleration may be positive when speed remains the same.1 If the speed-time curve is linear or piecewise linear2, acceleration is, as stated above, merely the slope of the line segment. If, however, the graph is a smooth curve, then changing acceleration is represented. In other words, the rate of change of velocity -- delta-V over delta-T -- is not a constant. In that case, the slope of the line segment tangent to the curve at any given point is the acceleration at that point. Note 1: There is a discussion comment on this point.Note 2: See the web link for an example of a graph that is piecewise linear.
Can the average speed ever equal the instantaneous speed?
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
Do acceleration and momentum mean the same thing?
No, acceleration and momentum are not the same. Acceleration refers to the rate of change of an object's velocity, while momentum is the product of an object's mass and velocity. Acceleration measures how quickly an object's velocity is changing, while momentum is a property that depends on both an object's mass and how fast it is moving.
What can be determined from a velocity time graph?
The simplest answer is the velocity of an object at a given time. It is also possible to determine the acceleration and displacement - but only in the same direction as the velocity. No information on motion in a transverse direction can be determined.
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position with respect to time, while acceleration is the rate of change of an object's velocity with respect to time. In other words, acceleration measures how quickly an object's velocity is changing.
Is it possible for a body to have the same acceleration and velocity?
The velocity and acceleration can have the same numeric value, but the units will be different. ----------------------------------------------------------------------------------------- No it is not possible. Because so long there is acceleration then the velocity has to change either in magnitude or in direction or in both. So it is not at all possible for acceleration and velocity to be the same simultaneously.
Are speed and acceleration the same?
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
When a cart is changing direction is it acceleration?
Yes, changing direction involves acceleration because acceleration is the rate of change of velocity. When an object changes direction, its velocity changes, which means it is experiencing acceleration.
What happens to the velocity if acceleration is zero?
The velocity stays the same, it is constant
What is the direction of instantaneous acceleration?
The direction of instantaneous acceleration is in the direction of the change in velocity at that moment. If the velocity is increasing, the acceleration is in the same direction as the velocity. If the velocity is decreasing, the acceleration is in the opposite direction of the velocity.
Are instantaneous velocity and acceleration the same?
no.
