The area under the velocity-time curve between times t1 and t2 is equa...
Explanation:
The area under the velocity-time curve represents the displacement of the object during that interval of time. This can be explained using the basic concept of calculus and the relationship between velocity and displacement.
Understanding the velocity-time curve:
The velocity-time curve represents how the velocity of an object changes over time. The velocity is plotted on the y-axis, and time is plotted on the x-axis. The shape of the curve depends on the motion of the object. For example, if the object is moving with constant velocity, the curve will be a straight line parallel to the x-axis. If the object is accelerating or decelerating, the curve will be curved.
Using calculus to find displacement:
To find the displacement of an object during a given interval of time, we can use calculus and integrate the velocity function with respect to time. Integration represents the area under the curve.
Explanation of the options:
a) Average velocity of the object during that interval of time: The average velocity is calculated by dividing the total displacement by the total time. It is not directly related to the area under the velocity-time curve.
b) Path length of the object during that interval of time: The path length is the total distance traveled by the object. It is not directly related to the area under the velocity-time curve.
c) Velocity of the object during that interval of time: The velocity of the object at a specific time can be determined from the velocity-time curve. However, the area under the curve does not represent the instantaneous velocity at any particular time.
d) Displacement of the object during that interval of time: The area under the velocity-time curve represents the change in displacement of the object during that interval of time. By integrating the velocity function, we can find the total area under the curve, which gives us the displacement.
Conclusion:
The area under the velocity-time curve between times t1 and t2 represents the displacement of the object during that interval of time. This is because integration of the velocity function gives us the total area under the curve, which represents the change in displacement.
