A light ping-pong ball and a heavy rubber ball of exactly the same size are each launched at the same angle and initial velocity, but the rubber ball goes much farther than the ping-pong ball. Draw a Free Body diagram for each object and use the concept of Drag Force and Terminal Velocity to prove that the problem statement is correct.

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
