Question 4
FA student drops a ball from a height of 1.2 m onto a hard floor. Figure shows two energy bar charts drawn on the same scale. Chart P shows the energy stores of the ball just after it is released. Chart Q shows the energy stores of the ball just before it hits the floor.
Figure: Energy bar charts for the ball just after release and just before it reaches the floor
a.[1]
Use Figure to give the energy in the gravitational potential energy store of the ball just after it is released.
b.[3]
Use Figure to describe how the energy in the system is redistributed as the ball falls.
c.[2]
The total height of the two bars in chart Q is the same as the height of the single bar in chart P. Explain what this shows about the energy in the system.
d.[1]
The student drops the same ball from a greater height. Give the effect of this on the height of the kinetic energy bar in chart Q.
