give the distance time graph of a moving body on which balanced force are applied??
Answers
Answer:
Distance-time graphs of motion
Distance-time graphs
Distance-time graphs show how the distance travelled by a moving object changes with time.
These graphs also show if the object is moving at a constant speed or accelerating, going back to the starting point, or stationary.
A distance-time graph showing how the distance travelled by a moving object changes with time. 3 coloured lines on the graph represent different speeds.
Constant speed is shown by a straight rising line. The gradient or the steepness of the graph can be used to work out the speed. A steep line means the vehicle is moving fast.
A line curving upwards means that the vehicle is accelerating. The vehicle is getting faster as the line is getting steeper.
A flat horizontal line means the vehicle is still, as the distance isn’t changing.
A distance-time graph with 2 coloured lines. 1 shows steady speed, the other shows steady speed, then stationary, then steady speed again.
The speed of the vehicle following the green line for the first 3 seconds is speed = distance ÷ time = gradient = 6 m ÷ 3 s = 2 m/s.
The total distance travelled by the vehicle on the green line is 7 m.
The mean speed of the vehicle on the green line is, average speed = total distance ÷ total time = 7 m ÷ 10 s = 0.7 m/s.
The speed of the vehicle following the purple line for the first 2 seconds is speed = distance ÷ time = gradient = 10 m ÷ 2 s = 5 m/s.
Look at this distance-time graph and answer the following questions.
A distance-time graph. The line starts at 0. and after 4 seconds reaches 30 meters. From 4 to 8 seconds the line remains at 30 meters. From 8 to 10 seconds the line rises from 30 meters to 40 meters.
when balance force acting on a body then external force on it is zero . Hence, the motion of the body is uniform and it covers equal distance in equal interval of time. distance time graph is a straight line in inclined to the time access.
