Work and Kinetic Energy (Ch. 7)

Question 1

kinetic energy (K)

Answer 1

• The energy an object with mass, m, will possess when traveling with speed, v
• K = ¹/₂mv²
  
  • Unit: Joules
  • Scalar

Question 2

work-energy theorem

Answer 2

• The total work done on an object is equal to the change in its kinetic energy.
• W_total = ΔK = ¹/₂mv_f² - ¹/₂mv_i²
