Welcome to your Module 7.0: Kinetic Energy in Golf Grades 6-8 Teacher Email Is this your pre or post assessment? (Pre-Assessment = 1, Post-Assessment = 2) Student ID Grade 1. Which statement correctly explains how changing the mass will impact kinetic energy? a. If velocity is constant, increased mass will increase kinetic energy. b. If velocity is constant, increased mass will decrease kinetic energy. c. If velocity is constant, decreased mass will increase kinetic energy. d. Mass does not affect kinetic energy. 2. What is the equation for kinetic energy? a. K=2mv2 b. K=2vm2 c. K=1/2vm2 d. K=1/2mv2 3. Two players each hit a golf ball with a mass of .046 kg: Player One’s drive has a velocity of 80 m/s and Player Two’s drive has a velocity of 70 m/s. What is the difference in kinetic energy between the two drives? a. Player One’s drive has 0.23 more joules of kinetic energy. b. Player One’s drive has 34.5 more joules of kinetic energy. c. Player One’s drive has 138 more joules of kinetic energy. d. Player One’s drive has 486 more joules of kinetic energy. Time is Up! Are you ready to learn more about STEM Sports®? ORDER STEM KITS
