What is a St graph?
Speed-Time Graphs look much like Distance-Time graph. Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis A straight horizontal line on a speed-time graph means the speed is constant. This means the speed is not changing over time. The slope of the S-t graph is speed.
What does St area graph represent?
The area under distance time graph gives nothing. Therefore, the area under the curve of the velocity time graph gives distance covered by the body. Note: The gradient of the curve in the distance time graph defines the velocity of the body. The area under the curve can be calculated by integrating the curve.
What are the uses of St graph?
The various uses of a distance-time graph are as follows:
- It tells us about the position of the body at any instant of time.
- From the graph, we can see the distance covered by the body during a particular interval of time.
- It also gives us information about the velocity of the body at any instant of time.
What does the slope of St graph gives?
The slope of s-t graph gives velocity, INSTANTANEOUS VELOCITY.
What is accelerating uniformly?
Translation: If an object’s speed (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn’t have uniform acceleration. uniform acceleration.
What is significant about the area of an XT graph?
The area under a speed-time graph is the distance. An area beneath the x-axis has a negative value. An area above the x-axis has a positive value. Be careful when calculating the total displacement, when summing the displacements remember to include the + and − signs of the displacements.
What does area under XT graph gives?
Area under velocity-time graph gives the displacement of a moving object whereas slope of velocity-time graph gives the acceleration.
What are the uses of St graph and VT graph?
(i) To determine the speed of a body at any instant of time. (ii) To determine the acceleration of a body. (iii) To determine the total distance travelled by a body in a given time-interval.
What is difference between distance and displacement?
Distance is a scalar quantity that refers to “how much ground an object has covered” during its motion. Displacement is a vector quantity that refers to “how far out of place an object is”; it is the object’s overall change in position.
Can a body have zero velocity and non zero acceleration?
Answer: Yes, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction. While observing the object, you will find that the object will continue to move forward for some time and then stops instantly.
