velocity time graph of a body is slown as?
Answers
Answer:
The slope of the curve in a velocity – time graph gives the acceleration.
Step1:Slope of velocity-time graph
Slope of velocity – time graph gives acceleration as shown below:
slope=
Δt
Δv
=a
Step2:Conclusion from graph
According to the graph of the question, the initial velocity of the body at time t=0 is OA. The slope of the graph is constant but negative.
Acceleration is a vector quantity having both magnitude and direction. Increase in velocity with respect to time is called acceleration whereas decrease in velocity with respect to time is called retardation. In this graph, the velocity is decreasing at a constant rate with respect to time. Hence, the body shows uniform retardation.
Answer:
A velocity-time graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object
