Tennis Module 6.0: Stroke of Energy: Grades 6-8 Welcome to your Tennis Module 6.0: Stroke of Energy: Grades 6-8 Teacher Email Student ID Is this your pre or post assessment? Pre-Assessment Post-Assessment Grade 3rd 4th 5th 6th 7th 8th 1. To use the formula KE=1/2mv², the following units must be used:Kinetic energy is measured in Mass is measured in Velocity is measured in Word Bank: grams, kilograms, meters, meters per second, meters per second2, Newtons2. A tennis ball is hit at a velocity of 30 m/s. What is the kinetic energy of that ball? (The mass of a tennis ball is 0.057 kg) a. 1.71 Newtons b. 0.10 Newtons c. 51.3 Newtons d. 512 Newtons None 3. The Kinetic Energy(KE) of a tennis ball can be found using the equation KE=1/2mv²; m is the mass of the ball, and v is the velocity. If the velocity of the ball is doubled, what happens to the kinetic energy? a. The kinetic energy is half of the original kinetic energy. b. The kinetic energy is the same as the original kinetic energy. c. The kinetic energy is double the amount of the original kinetic energy. d. The kinetic energy is quadruple the amount of the original kinetic energy. None Time's up
