P-3+Energy

​
 * ====Standard P-3:==== || ====The student will demonstrate an understanding of the conservation, transfer, and transformation of mechanical energy.==== ||
 * Indicators:**
 * || P-3.1 || [|Apply energy formulas to determine potential and kinetic energy and explain the transformation from one to the other.] ||
 * || P-3.1 || [|Apply energy formulas to determine potential and kinetic energy and explain the transformation from one to the other.] ||

When the rock hits the ground, there is no longer any kinetic energy. 7.Silvana Cruciata from Italy set a record in one-hour running by running 18.084km in 1.000h. If Cruciata's kinetic energy was 694 J, what was her mass?


 * || P-3.2 || [|Apply the law of conservation of energy to the transfer of mechanical energy through work.] ||

4. 5. 6. 7.


 * || P-3.3 || Explain, both conceptually and quantitatively, how energy can transfer from one system to another (including work, power, and efficiency). ||

In order to make the clock go at a proper rate, the pendulum must be lengthened in order to extend the time of the period. 7. 4. 5.

For example, a strong gust of wind may alter the momentum of the ball, or the ball may be hit by another player swinging a bat. 7. The world's most massive train ran in South Africa in 1989. Over 7 km long, the train traveled 861 km in 22.67 h. Imagine the the distance was traveled in a straight line north. If the train's average momentum was 7.32 X 10^8 kg*m/s to the north, what was its mass? 4. 5.Links 6. 7. ||
