What is the gradient of a VT graph?

What is the gradient of a VT graph?

If an object moves along a straight line, its motion can be represented by a velocity-time graph. The gradient of the line is equal to the acceleration of the object.

What can be calculated from the gradient of a velocity time graph?

A horizontal line on a velocity-time graph, shows that the object is at constant velocity, but a sloping line on a velocity-time graph, shows that the object is accelerating. The gradient of the line is equal to the acceleration of the object.

What is the value of the slope of the velocity time graph for any free falling object?

A motion such as the one above further illustrates the important principle: the slope of the line on a velocity-time graph is equal to the acceleration of the object.

What is the velocity time graph for free fall?

Representing Free Fall by Velocity-Time Graphs As learned earlier, a diagonal line on a velocity versus time graph signifies an accelerated motion. Since a free-falling object is undergoing an acceleration (g = 9,8 m/s/s, downward), it would be expected that its velocity-time graph would be diagonal.

Will the slope be equal to 1 if the acceleration is zero?

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

What is the gradient of acceleration time graph?

The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

Can a body have zero velocity and still acceleration give example?

Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up. At the peak point its velocity becomes 0 but still accelerates due to gravity.

What is the slope of free falling object?

The slope of a velocity – time graph for the free fall of a body under gravity, starting from rest is (Take g = 10 m s^-2 .)

What does the slope of a V-T graph mean?

The Meaning of Slope for a v-t Graph. If the acceleration is negative, then the velocity-time graph is a downward sloping line (i.e., the slope is negative). If the acceleration is great, then the line slopes up steeply (i.e., the slope is great). This principle can be extended to any motion conceivable.

What is the gradient of the acceleration time graph?

It was learned earlier in Lesson 4 that the slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.

How is the slope of a velocity graph related to acceleration?

Slope of v-t Graphs Area Under v-t Graphs It was learned earlier in Lesson 4 that the slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.

How are velocity and time graphs used to represent free fall?

Representing Free Fall by Velocity-Time Graphs. As learned earlier, a diagonal line on a velocity versus time graph signifies an accelerated motion. Since a free-falling object is undergoing an acceleration (g = 9,8 m/s/s, downward), it would be expected that its velocity-time graph would be diagonal.
