What does a speed time graph show?
The acceleration of an object.
What does a horizontal line on a acceleration graph mean?
This means that it has a constant acceleration. It DOES NOT mean that the object is at rest.
What does the area under an acceleration time graph show?
The area under an acceleration-time graph is equal to the object's velocity (not change in velocity).
What kinematic concept distance velocity acceleration etc of the moving object does the slope of the graph represent?
acceleration
What does the slope of a speed vs time graph indicate about an object's motion?
The slope of the speed/time graph is the magnitude (size) of the object's acceleration.
How would you obtain the acceleration of an object from a velocity time graph?
The average acceleration can be obtained by finding the slope of the graph. The instantaneous acceleration is found by drawing a tangent to a particular point on the graph (instant) and finding the slope of than tangent.
What does the graph of force vs. acceleration imply?
The graph of force versus acceleration tells us that there is a direct relationship between the force applied to an object and the amount of acceleration that object experiences. More force applied, more acceleration, and much more force applied yields much more acceleration.
What does the slope of a distance uersus time graph show you about the motion of an object?
acceleration.
How can a position time graph show if an object has constant acceleration?
With a straight line.
What information can be learned from a position time graph and a speed time graph?
A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.
How is an object moving if a slanted straight line on a speed-versus-time graph represent its motion?
The slope (gradient) of a speed v time graph is acceleration. If the graph is a straight line, then the acceleration is constant. if the slope is 0 (ie the line is horizontal) then the acceleration is 0, and the object is moving with a constant speed (which can be 0, ie the object is stationary). If the graph is "slanted" then depending upon which way the line is "slanted" the object is accelerating or decelerating (the steepness of the slope gives the rate of this). So the object is moving with constant acceleration and either speeding up or slowing down - which, and by how much, depends upon the gradient of the graph.
Can acceleration ever be negative?
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
