Assignment: Reflect on the Lab Active
Analyzing the Relationship between Mass and KE
Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a
100 kg ball traveling at 5 m/s.
A 1,000 kg ball traveling at 5 m/s would have
v kinetic energy
A 10 kg ball traveling at 5 m/s would have
✓ kinetic energy
A 100 kg person falling at 5 m/s would have
v kinetic energy

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
