Potential Difference and Current Calculations Worksheet with Answers London WC1R 4HQ. Questions for pupils to practice using and re-arranging the kinetic energy equation. registered in England (Company No 02017289) with its registered office at 26 Red Lion Explain your answer. E k = 1 2 mv2 =0.5 x (1.5x104) x (11580)2 =1.006 x 1012J so Kinetic Energy gained = final E k - initial E k = 1.006 x 1012J - 2.028 x 1011J = 8.032 x 1011J (c) If the rocket is in space and the engine is then switched off, what will happen to the rocket speed? Kinetic and Potential Energy Worksheet. This tells us 10 lo- kinetic energy of photoelectrons/ J 5x 101 frequency/Hz (i) Use the graph to find the threshold frequency for metal X. An object moving with a speed of 67 m/s and has a kinetic energy of 500 J, what is the mass of the object. The wind blowing through your hair __K___ 2. Classify the following as a type of potential energy or kinetic energy (use the letters K or P) 1.A bicyclist pedaling up a hill __K___ 6. AQA GCSE Physics & Combined Science Physics Required Practical Revision 9-1, Physics Paper 1 Revision AQA Trilogy Foundation, Team Quest Christmas 2020 - Team Building Quiz for KS3. KE = ½ mv2 2 KE = 500J m = ? Final Kinetic Energy: using ! The maximum kinetic energy of the photoelectrons emitted from metal X is measured for a number of different frequencies of the radiation. 6.
