what type of d-t graph is this

changing

Choose YES or NO: Can the distance-time graph be used to represent the non-uniform motion of the body?

YES Explanation: The distance-time graph can indicate both the uniform and non-uniform motion of the body.

Which among the following graphs is not possible? a.Displacement time graph b.Time-time graph c.Distance time graph d.Velocity time graph

b) Time-time graph Explanation: We cannot plot the time-time graph since both parameters are the same.

In a distance-time graph, which variable is plotted on the Y-axis? a.Velocity b.Speed c.Time d.Distance

Distance Explanation: In a distance-time graph, distance is plotted on the y-axis and time on the x-axis.

The slope of a distance-time graph represents _____ a.Velocity b.Speed c.Acceleration d.Displacement

Speed Explanation: Speed is indicated by the distance-time graph.

Distance-time graph shows a curved line in which type of motion?

Distance-time graph shows a curved line in non-uniform motion.

State true or false: A straight line on the distance-time graph indicates that the object is moving at a constant speed. TRUE FALSE

TRUE

Carol is running at constant velocity. Below is the displacement-time graph for the first 10 s of her run. Displacement-time graph for the first 10 seconds of a jog. What is Carol’s displacement after 6 s?

Carol’s displacement is 24 m.

This is a speed-time graph for a car moving between two sets of traffic lights. What is the rate of change of speed of the car between 0 s and 10 s?

rate of change of speed = (16 m/s – 0 m/s) ÷ 10 s = 1.6 m/s2
