  2. Objectives: (QCC 175, 180, 182) • 1. Identify the various types of energy sources. • 2. Compute the quantity of energy used in agriculture applications. • 3. Measure the energy produced from various sources

  3. Energy is the ability to do work. .Work can be defined as the transfer of energy as the result of motion and is measured in joules. Acceleration is the rate of change in velocity and is represented by M/S2 . A force is the push or pull one body exerts on another and is measured in newtons. • A. Note: One (1) Newton = 1 KG x 1 Meter/seconds2 or the force needed to move 1 KG x 1 Meter/seconds2. • B. Force (F) = Mass (M) x Acceleration (A)

  4. MATERIALS AND EQUIPMENT • Calculator, Yo-Yo, paddle ball, miniature tractor, battery charger, stop watch, and tape measure.

  5. DEMONSTRATION: WITH PADDLE BALL • Measure distance ball falls from paddle.-50.5 cm • Weigh the ball.-8.86 grams • Time the ball from paddle to end of cord.-.32 seconds • Calculate the amount of work in joules.

  6. W(work)=F(force) x D(distance traveled) • F=.009x.51/.322 • F=. 009x .51/.102 • F=. 009x 5 • F=.045 newtons

  7. ACTIVITY/EXPERIMENTS: WITH ENERGY, FORCE, AND WORK. WITH YO-YO • Measure string on Yo-Yo.-41 centimeters • Weigh the Yo-Yo.-48.5grams • Time fall of the Yo-Yo from hand to end of string.-.81 seconds • Calculate the force on the Yo-Yo.

  8. F(force)=M(mass)xA(acceleration • F=.049x.41/.812 • F=.049x.41/.66 • F=.049x.62 • F=.03 newtons

  9. Activity/Experiments: with energy force and work • Build Track. • Make model mini-tractor. • Connect battery charger to track. • Measure the distance the tractor moved.-1 meter • Weigh the tractor.-380.35 grams • Time movement of tractor.-1.25 seconds • Calculate force of the tractor.

  10. F=M x A • F=.38x1/1.252 • F=.38x1/1.56 • F=.38x.64 • F=.24 newtons
